Zener Diode (15V) 1.3 W 5pcs

The Zener Diode (15V) 1.3 W is a zener diode that holds a steady 15 V across it when connected in reverse with a series resistor, sold in a pack of 5. Its 1.3 W power rating lets it handle more current than small 0.5 W zeners, so it works well as a simple voltage regulator, a reference voltage or a clamp that protects inputs from voltage spikes.

Zener Diode (15V) 1.3 W Specifications

• Zener voltage: 15 V
• Power rating: 1.3 W
• Maximum zener current: about 86 mA in theory (1.3 W ÷ 15 V); stay well below it
• Type: zener diode, two leads, cathode marked with a band
• Pack size: 5 pieces

Zener Diode (15V) 1.3 W Applications

• Simple shunt voltage regulators around 15 V
• Gate-source clamps that keep MOSFET gates below 15 V
• Overvoltage clamping on inputs
• Reference voltages for comparators and monitors
• Repair of power supplies and chargers

What's in the Box

• 5 × 15 V 1.3 W zener diodes

Tip: Connect the band (cathode) to the positive side and always use a series resistor: R = (Vin − 15 V) ÷ I. For example, from 24 V at 20 mA use about 450 Ω (470 Ω standard), and check that resistor's power rating too.
