Collector-Emitter Saturation Voltage vs Collector Current. 2N3904 -> MMBT3904 MPSA42 -> MMBTA42 2N7000 -> 2N7002 (odd one out?) I don't know of any SMT equivalent of the BC108 or 2SC1815. UNISONIC TECHNOLOGIES CO. All Stats Differences Only. I have 5 pieces of 2N4401 genuine product from Fairchild (USA). When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads.

ELE 343 Electronics II. It is designed for low current and power, medium voltage, and can operate at moderately high speeds. BC548 transistor can be used in many general purpose applications; you can use it in the replacement of other general purpose transistor 2N3904, BC547 etc. Here other small NPN transistor can be used, including 2N4401, 2N2222 or PN2222. One with a similar threshold to the BSS138, (logic-level). The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. Use a transistor curve tracer to measure the small-signal current gain, β, of the 2N4401 and 2N3904 NPN BJTs for collector current used above. 数量 (IRG4PC30KD) 价格 (元/IRG4PC30KD) 1. Can't give any real details other than these. 2N2222A, 2N3904, 2N4401. Transistor technology just keeps improving. little more capacitance from the collector (connected to the case) to. Although the IC1 4069 contains protection circuitry against damage from ESD , use common sense when handling this device. Sometimes you might need to rely on one of these differences. Although I initially tried both 2N3904 and 2N2222 transistors in this circuit, I found that 2N4401’s work best, probably because their gain is a weaker function of collector current than the. ในการค้นหาขอบเขต / ลอจิกตัววิเคราะห์พีซีที่ไม่แพงมากฉันได้พบอุปกรณ์เล็ก ๆ ที่ดูดีมากและฉันรู้ว่ามันจะทำงานได้ดี อย่างไรก็ตามเมื่อดูจาก.

It is used for audio amplification and high frequency oscillator (OSC). OldSteve June 23, 2016, 10:52am #3. 東芝トランジスタ2SC1815の代品 東芝トランジスタ2SC1815が廃止になるそうです。いままで汎用npnトランジスタといえば自動的に、暗黙的に、オウム返し的に2SC1815が出てきたのですが、これからはそうもいかないわけで、バベルの塔崩壊以来の言語の乱立に似た大混乱が起こりかねません. 40 V NPN General Purpose Bipolar Junction Transistor, 2000-REEL.
