Product details
Overview
VS-32CTQ030SHM3 from Vishay Semiconductors is a high-performance dual common-cathode Schottky rectifier optimized for low reverse leakage at 150 °C junction temperature, with 30 V reverse voltage rating, 30 A average forward current (2 × 15 A), and 0.40 V forward voltage drop at 15 A and 125 °C - used in automotive DC/DC converters and industrial freewheeling circuits.
For engineers reviewing the VS-32CTQ030SHM3 datasheet, VS-32CTQ030SHM3 pinout, VS-32CTQ030SHM3 application, or VS-32CTQ030SHM3 equivalent, key selection criteria include AEC-Q101 qualification, D2PAK (TO-263AB) thermal performance (RthJC = 3.25 °C/W per leg), and low dV/dt sensitivity (10 kV/μs) in high-frequency switching topologies.
Technical Context
This device integrates two independent Schottky die in a single D2PAK package with shared cathode terminal, enabling compact dual-diode configurations for synchronous rectification and bidirectional clamping. Its proprietary barrier technology ensures stable operation up to 150 °C TJ while maintaining <97 mA typical reverse leakage at 125 °C and rated VR.
The low 9.09 mΩ forward slope resistance and 1300 pF junction capacitance per leg support high-efficiency, high-frequency (>100 kHz) power conversion. It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 1A whisker testing, confirming suitability for automotive under-hood environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3030CGY | 30 V, 30 A, TO-247AC package; higher RthJC (4.0 °C/W); no AEC-Q101 qualification. | Preferred for industrial mains-powered PSUs where automotive qualification is unnecessary. | Select when higher surge margin (IFSM = 1000 A) is prioritized over thermal performance and automotive compliance. |
| ON Semi NRVB3030CTT4G | 30 V, 30 A, D2PAK; 0.45 V VF @ 15 A/125 °C; AEC-Q101 qualified but MSL Level 2a (floor life = 1 year). | Suitable for cost-sensitive automotive body electronics where extended floor life is not required. | Choose when procurement logistics favor ON Semi's distribution network and MSL Level 1 is not mandatory. |
Compared with STPS3030CGY and NRVB3030CTT4G, the VS-32CTQ030SHM3 delivers superior thermal management (3.25 °C/W), guaranteed MSL Level 1 handling, and lower forward voltage - making it optimal for space-constrained, thermally aggressive automotive power modules.

FAQ
What is the maximum junction temperature rating for the VS-32CTQ030SHM3?
The VS-32CTQ030SHM3 has a maximum junction temperature (TJ(max)) of +150 °C, validated through AEC-Q101 stress testing and supported by its proprietary barrier technology. This rating allows uninterrupted operation in under-hood automotive environments and high-ambient industrial enclosures without thermal derating below full current capacity.
Is the VS-32CTQ030SHM3 pin-compatible with other Vishay D2PAK Schottky rectifiers like the VS-32CTQ025SHM3?
Yes, the VS-32CTQ030SHM3 shares identical D2PAK (TO-263AB) mechanical footprint, pinout (anode-anode-cathode), and thermal pad layout with the VS-32CTQ025SHM3 and all VS-32CTQ...SHM3 series devices. Only the reverse voltage rating differs (30 V vs. 25 V), allowing direct PCB-level substitution where voltage margin permits.
Does the VS-32CTQ030SHM3 support high-frequency switching above 500 kHz?
Yes, the VS-32CTQ030SHM3 supports high-frequency operation due to its low junction capacitance (1300 pF per leg at 5 V) and fast recovery characteristics. Its 10,000 V/μs dV/dt rating and absence of minority-carrier storage enable clean commutation in GaN-based 650 kHz DC/DC converters without oscillation or shoot-through risk.
What is the avalanche energy rating (EAS) of the VS-32CTQ030SHM3 and how is it tested?
The VS-32CTQ030SHM3 has a non-repetitive avalanche energy rating (EAS) of 13 mJ, measured per JEDEC standard at TJ = 25 °C with IAS = 1.20 A and L = 11.10 mH. This value reflects its ability to absorb inductive energy during unclamped switching events - critical for motor drive freewheeling and synchronous rectifier fault conditions.
How does the VS-32CTQ030SHM3 achieve low reverse leakage at elevated temperatures?
The VS-32CTQ030SHM3 achieves <97 mA typical reverse leakage (IRM) at 125 °C through Vishay's proprietary Schottky barrier optimization, which minimizes thermionic emission and tunneling currents. This is confirmed in the datasheet's Fig. 2 and enables reliable operation in automotive engine bay applications where ambient temperatures exceed 105 °C.
