BZG03C91-M3-18 Description

Short technical summary and product information.

The BZG03C91-M3-18 is a 91V uni-directional Zener diode from Vishay Dale's BZG03C-M series. It is designed for voltage stabilization and protection applications in a compact surface mount package.

Key electrical specifications include a nominal Zener voltage of 91V with a tolerance of ±6.04%, maximum power dissipation of 1.25W when thermal resistance from junction to ambient is less than 100 K/W, and up to 3W when RthJA is below 25 K/W. The dynamic impedance is 200Ω at 2mA test current. Reverse leakage current is 1µA maximum at 68V reverse voltage. Forward voltage is 1.2V maximum at 500mA. The diode operates over a junction temperature range of -65 to +150°C.

The device is housed in a DO-214AC (SMA) surface mount package, weighing 64 mg. It is supplied in tape and reel packaging with 7500 units per 13" reel (minimum order quantity 7500). The package is rated MSL level 1 per J-STD-020 and has a flammability rating of UL 94 V-0. Soldering conditions allow a peak temperature of 260°C.

This Zener diode is RoHS-compliant and halogen-free. AEC-Q101 qualified versions are available for automotive applications. The BZG03C91-M3-18 is suitable for voltage regulation, overvoltage clamping, and as a reference element in various electronic circuits.
