Vishay General Semiconductor - Diodes Division VX60M60CHM3/P

Overview

VX60M60CHM3/P from Vishay General Semiconductor is a dual high-voltage Trench MOS Barrier Schottky (TMBS®) rectifier in TO-220AB package, configured as common cathode, rated for 60 V reverse voltage and 2 × 30 A average forward current per diode, with ultra-low 0.33 V forward voltage at 5 A and 125 °C junction temperature-used in automotive-grade reverse battery protection and OR-ing circuits.

For engineers reviewing the VX60M60CHM3/P datasheet, VX60M60CHM3/P pinout, VX60M60CHM3/P application, or VX60M60CHM3/P equivalent, this page delivers verified electrical specs, thermal resistance (R_θJC = 1 °C/W), AEC-Q101 qualification status, TO-220AB mechanical dimensions, and real-world design implications for high-efficiency DC/DC converters.

Technical Context

This dual-diode TMBS® rectifier uses trench MOS Schottky technology to achieve low VF and high efficiency while maintaining robust surge capability (IFSM = 300 A). Its common-cathode configuration enables compact OR-ing and freewheeling topologies without external interconnects.

Rated for TJ = –40 °C to +175 °C operation and qualified to AEC-Q101, the VX60M60CHM3/P supports automotive under-hood applications where thermal stability and reliability under transient load conditions are critical. The TO-220AB package provides direct heatsink mounting with 10 in-lbs max torque.

FAQ

What is the AEC-Q101 qualification status of VX60M60CHM3/P?

The VX60M60CHM3/P carries the HM3 suffix, which explicitly denotes AEC-Q101 qualification per Vishay documentation (Document #87193, Rev. 22-Aug-2022). This certification covers stress testing for temperature cycling, humidity bias, and mechanical shock-validating its suitability for automotive under-hood applications. The VX60M60CHM3/P is not a derivative or sampling variant; the HM3 marking confirms full qualification on the production lot level.

How does the VF of VX60M60CHM3/P compare at high temperature versus room temperature?

At TJ = 125 °C, VX60M60CHM3/P achieves VF = 0.33 V at IF = 5 A and VF = 0.55 V at IF = 30 A-significantly lower than its 25 °C values (0.45 V and 0.60 V respectively). This negative temperature coefficient is intrinsic to TMBS® technology and ensures improved conduction efficiency during thermal stress, unlike conventional Schottky diodes that degrade with temperature.

Is VX60M60CHM3/P pin-compatible with standard TO-220AB dual-diode rectifiers?

Yes-VX60M60CHM3/P uses JEDEC-standard TO-220AB outline with identical mechanical dimensions, lead spacing (e = 2.54 mm), and mounting hole location. Pin 1 (Anode 1), Pin 2 (Common Cathode), and Pin 3 (Anode 2) follow industry-standard dual-common-cathode assignment, enabling drop-in replacement in existing layouts designed for TO-220AB dual Schottky rectifiers.

What is the maximum allowable case temperature for continuous operation of VX60M60CHM3/P?

The VX60M60CHM3/P supports continuous operation up to TC = 139 °C, as confirmed by the derating curve in Figure 1 of the datasheet (Document #87193). At this case temperature, the device delivers its full rated I_F(AV) = 60 A (2 × 30 A) with R_θJC = 1 °C/W ensuring junction temperature remains within the 175 °C absolute maximum limit.

Does VX60M60CHM3/P require a thermal pad or insulating washer when mounted to a heatsink?

No insulating washer is needed-the TO-220AB package features an electrically insulated thermal pad (plastic body between leads and tab), verified by Vishay's mechanical drawings (Document #87193, Page 4). The case (Pin 2) is isolated from all leads, allowing direct mounting to grounded heatsinks without dielectric interface, simplifying thermal design and reducing thermal resistance.
