This data sheet provides detailed information on the CMZ5921B-CMZ5956B series of products, including the product model, rated voltage, maximum current, and operating temperature.
Central Semiconductor’s 1.5 W surface‑mount silicon Zener diodes are designed for commercial, industrial, entertainment, computer and automotive applications where a small footprint is required. The SMA case occupies about 30 % less board space than the larger SMB case.
Key specifications include a maximum power dissipation of 1.5 W, peak forward surge current of 20 A, thermal resistance QJA of 139 °C/W, and a forward voltage of 1.5 V at 200 mA. The product family covers Zener voltages from 6.8 V up to 200 V with a tight ±5 % tolerance.
| Power Dissipation (PD) | 1.5 W |
|---|---|
| Peak Forward Surge Current (IFSM) | 20 A |
| Thermal Resistance QJA | 139 °C/W |
| Minimum Zener Voltage | 6.8 V |
| Maximum Zener Voltage | 200 V |
| Forward Voltage (VF) at 200 mA | 1.5 V |
| Zener Voltage Tolerance | ±5 % |
The diodes can dissipate up to 1.5 W of power.
All Zener voltages are specified with a ±5 % tolerance.
The peak forward surge current is rated at 20 A for an 8.3 ms pulse.
The forward voltage is 1.5 V when the diode conducts 200 mA.
