Diodes Incorporated APD160VD-G1

Overview

APD160VD-G1 from Diodes Incorporated is a dual anode, common cathode Schottky barrier rectifier in DO-41 package, rated for 60 V repetitive peak reverse voltage, 1 A average forward current, and 0.68 V maximum forward voltage at 1 A and +25°C. It delivers low conduction loss and high surge capability (35 A peak) for DC-DC converters and polarity protection circuits operating up to +125°C junction temperature.

For engineers reviewing the APD160VD-G1 datasheet, APD160VD-G1 pinout, APD160VD-G1 application, or APD160VD-G1 equivalent, key selection criteria include forward voltage drop at 1 A, reverse leakage at +100°C, thermal resistance (80°C/W), surge rating, and RoHS-compliant "Green" packaging with matte tin annealed leads.

Technical Context

This dual Schottky rectifier integrates two anode terminals sharing one cathode, enabling synchronous rectification or dual-path low-loss DC output. Its guard-ring structure enhances ruggedness against transient stress, while the low-junction-capacitance design (91 pF at 4 V) supports high-frequency switching up to several hundred kHz.

The device operates across –65°C to +125°C junction range and exhibits 0.5 mA max reverse leakage at rated 60 V and +25°C - rising to 10 mA at +100°C - requiring careful thermal management in high-ambient environments where θ_JA = 80°C/W applies under standard DO-41 mounting conditions.

Key Specifications

Pinout & Package

APD160VD-G1 uses the DO-41 axial-leaded plastic package with cathode identified by a band marking. The device has three external terminals: Anode 1, Anode 2, and Common Cathode - configured as a dual-anode, single-cathode Schottky pair.

FAQ

What is the cathode marking convention for APD160VD-G1?

The cathode is marked by a distinct band on the DO-41 body, located adjacent to the cathode lead. Both anodes extend from the opposite end, unmarked. This matches standard industry polarity identification for axial diodes and ensures correct orientation during manual or automated placement.

Can APD160VD-G1 replace a single-anode Schottky diode in a freewheeling application?

Yes - when used with one anode tied to the switch node and the other anode left unconnected or grounded, the APD160VD-G1 functions as a single 1 A Schottky rectifier. Its dual-anode structure allows flexible routing but does not require both anodes to be active simultaneously.

Is APD160VD-G1 suitable for automotive under-hood applications?

No - although its junction temperature rating reaches +125°C, APD160VD-G1 is not AEC-Q200 qualified and lacks automotive-specific qualification testing (e.g., vibration, extended temperature cycling). It is intended for industrial and commercial power systems only.

How does the 80°C/W thermal resistance impact PCB layout?

At 1 A continuous current, the junction-to-ambient rise is ~55°C above ambient - requiring ≥25 mm² of 1 oz. copper connected to both leads. Without adequate copper area, the device exceeds +125°C junction limit even at room temperature, risking premature failure.
