<p>The 1SMB5914BT3G is a 3.6V Zener diode from On Semiconductor, part of the 1SMB59xxBT3G series of 3W plastic surface mount Zener voltage regulators. It offers a nominal Zener voltage of 3.6V with a tolerance of ±5%, and a maximum power dissipation of 3W at a lead temperature of 75°C. The device is designed for voltage regulation and overvoltage protection in a wide range of electronic circuits.</p><p>&nbsp;</p><p>With a Zener impedance of 9Ω and a reverse leakage current of 75µA at 1V, this diode provides stable and efficient voltage clamping. It also features a forward voltage of 1.5V at 200mA. The device is rated for ESD protection up to Class 3 (&gt;16 kV) per Human Body Model, making it robust for handling during assembly.</p><p>&nbsp;</p><p>Packaged in a DO-214AA (SMB) surface mount package, the diode has a modified L-bend lead style and is supplied in tape and reel packaging (2500 units per reel). The operating temperature range spans -65°C to 150°C, suitable for harsh environments. The thermal resistance from junction to lead is 25°C/W and from junction to ambient is 226°C/W on a standard FR-4 board.</p><p>&nbsp;</p><p>The 1SMB5914BT3G is Pb-free and RoHS compliant, with a flammability rating of UL 94 V-0. It is a reliable choice for voltage regulation in consumer, industrial, and automotive applications (automotive qualified versions are available with SZ prefix).</p>

<p>The BAS70-04LT1G is a Schottky barrier diode array designed for high-speed switching, circuit protection, and voltage clamping. It features extremely fast switching speed and low forward voltage, reducing conduction loss in portable and handheld applications.</p><p>&nbsp;</p><p>Key specifications include a maximum reverse voltage of 70 V, a forward current rating of 70 mA, and a non-repetitive peak forward surge current of 100 mA. The device offers low forward voltage options: 410 mV at 1 mA, 750 mV at 10 mA, and 1 V at 15 mA. Maximum reverse leakage is 0.1 µA at 50 V and 10 µA at 70 V. Total capacitance is 2.0 pF (max) at 0 V, 1 MHz.</p><p>&nbsp;</p><p>The diode is configured as 1 pair series connection and is housed in a surface-mount SOT-23-3 (TO-236, SC-59) package. It operates over a junction temperature range of -55°C to +150°C and has a maximum power dissipation of 225 mW at 25°C ambient. The device is RoHS compliant, Pb-Free, and Halogen Free/BFR Free.</p>
