Product details

Active production — a straightforward BOM line

The 1N6315 is an active-production zener diode from Microchip Technology, rated at 4.3 V nominal with a ±5% tolerance and 500 mW power dissipation. Its 20 Ohm maximum impedance (Zzt) and 2 µA reverse leakage at 1 V are typical for a 4.3 V zener in this power class — the low leakage matters for voltage-reference circuits where the diode sits across a high-impedance node.
