The 1SMB5933BT3 is a 22V Zener diode from ON Semiconductor, part of the 1SMB59xxBT3 series of 3W plastic surface mount voltage regulators. It offers a nominal zener voltage of 22V with ±5% tolerance and a maximum power dissipation of 3W at a lead temperature of 75°C (zero lead length). The diode features a low zener impedance of 17.5Ω (test condition not specified) and a reverse leakage current of 1µA at 16.7V. Forward voltage is 1.5V maximum at 200mA.
The device is housed in a DO-214AA (SMB) surface mount package with modified L-bend leads for improved solder joint reliability. It operates over a junction temperature range of -65°C to 150°C and has a thermal resistance of 25°C/W junction-to-lead and 226°C/W junction-to-ambient on standard FR-4 board. The diode is rated for ESD Class 3 (>16 kV) per the Human Body Model and has a flammability rating of UL 94 V-0.
Typical applications include voltage regulation, overvoltage protection, and reference circuits in consumer, industrial, and automotive systems. The part is supplied in tape and reel packaging with 2500 units per reel. Compliance with RoHS, REACH, and MSL Level 1 is indicated but unverified.
