1N4148.1N4448 Vishay Semiconductors Rev. 1.4, 06-Jul-17 3 Document Number: 81857 For technical questions within your region: DiodesAmericas@vishay.com, DiodesAsia@vishay.com, DiodesEurope@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. 2 of 3 . You should probably understand that the 1N4148 (or 914 for that matter) get selected for circuits more *because* they are readily available and not due to any specific traits. NTE Semiconductors NTE Part Number: NTE519 Description: SI-DIODE, FAST SWITCHING, 4 TO 8 ns + QTY Per Package: 1 QTY In Stock: 390 There is a 1-2 week lead-time for out of stock items. ��� Silicon epitaxial planar diode ��� Electrically equivalent diodes: 1N4148 ��� 1N914. That is the current should always flow from the Anode to cathode. Reverse Current vs. This diode has wide operating parameters, which makes it suitable for a range of uses involving power and small signal applications. Can a 1N4148 be substituted for a 1N4001? 0 #3 5 years ago AJO. If you are rectifying small low current signals then you can used a 1N4148. It is a high-speed switching junction diode, which consists of a slab of p-type and an n-type semiconductor material in close contact with each other. Package includes: 10 x 1N4148 Diodes. Hello everyone! It is like subbing a mustang for a camaro. beaver: 11/5/09 3:59 AM: It depends on your application. Looking at the Fairchild datasheet , the guaranteed max capacitance is less for the 916A/B and 4448 than the 914A/B/4184 (2pF vs. 4pF), and the forward voltage min/max ratings differ, but there's nothing I see that prevents them all from being made with a single die . The 4148 is a fast recovery diode. I got as far as the MMSD4148, but I suspect there are other "common" old-school diodes that have been converted to SMT.. Diode polarity Current can flow from the anode to the cathode only and never from the cathode to the anode ... Dimensions 1N4448 diode. The other is a general purpose diode. Dear all, Given the success in the last thread on transistors, I thought I would ask about SMT variants of the venerable 1N4148 diode.. Add to cart. The 1N4148 is a standard silicon switching diode. The term switching and rectifier refer to how the didoe is normally used in a cicuit. handbook, halfpage MAM246 k a Only difference is that 1n4148 has low leakage current than 1n914, but even for some manufacturers the leakage current is same for both the diodes. Useful for logic speed signals. What's the difference? 1N4148: High Conductance Fast Diode. 1N4148 Description. The 1N4148 is a general-purpose silicon junction diode encapsulated in a glass SOD27 (DO-35) package. Highland, IN 7y 85,800 3,770 4 8 How about that for timing.

GENERAL RULE: The Reverse Current of a diode will approximately double for every ten (10) Degree C increase in Temperature Figure 2. 1N4148 Diode (10 Pcs) quantity. ��� Electrically equivalent diodes: 1N4148 - 1N914 ... 1N4148 1N4148-TAP or 1N4148TR V4148 Single diode Tape and reel/ammopack ABSOLUTE MAXIMUM RATINGS (Tamb = 25 °C, unless otherwise specified) PARAMETER TEST CONDITION SYMBOL VALUE UNIT Repetitive peak reverse voltage VRRM 100 V Reverse voltage VR 75 V MARKING TYPE NUMBER MARKING CODE 1N4148 1N4148PH or 4148PH 1N4448 1N4448 Fig.1 Simplified outline (SOD27; DO-35) and symbol. Pinside member . Click here for the datasheet for NTE519. Instead it * improves modeling in the reverse * mode of operation. Here I am doing the same thing and wondering the same question. Compare. Since leakage is almost never a desirable property, manufacturers today produce the 1N4148 and sell it as either part number. But I think radioshack does sell the 1N32 or something similar, any germanium diode will be very similar. You didn't mentioned, in which circuit you are using it, if the use is not critical then you can even use many other equivalent diodes like 1N914, 1N914A, 1N914B, 1N916, 1N916A, 1N916B, 1N4148, 1N4448. 1N4148 ON Semiconductor / Fairchild Diodes - General Purpose, Power, Switching 100V Io/200mA BULK datasheet, inventory, & pricing.
