Product details
Overview
VS-32CTQ025-1HM3 from Vishay Semiconductors is a high-performance dual common-cathode Schottky rectifier rated for 25 V reverse voltage and 30 A total average forward current (2 × 15 A per leg), with 0.40 V forward voltage at 15 A and 125 °C junction temperature. It features AEC-Q101 qualification, 150 °C maximum junction temperature, and TO-262AA package - optimized for reverse battery protection and high-frequency DC/DC converters in automotive and industrial power systems.
For engineers reviewing the VS-32CTQ025-1HM3 datasheet, VS-32CTQ025-1HM3 pinout, VS-32CTQ025-1HM3 application, or VS-32CTQ025-1HM3 equivalent, key selection criteria include its low VF at high TJ, 97 mA typical reverse leakage at 125 °C, 13 mJ non-repetitive avalanche energy rating, and MSL Level 1 moisture sensitivity - critical for under-hood automotive designs requiring long-term reliability under thermal stress.
Technical Context
This dual-die Schottky rectifier uses proprietary barrier technology to achieve stable low-VF operation up to 150 °C TJ while minimizing reverse leakage at elevated temperatures. Its common-cathode configuration enables compact two-switch topologies in synchronous rectification and freewheeling paths.
The device supports high dV/dt capability (10,000 V/μs) and exhibits low series inductance (8.0 nH per leg), making it suitable for fast-switching applications such as 100–500 kHz DC/DC converters. Thermal resistance is specified at 3.25 °C/W (junction-to-case per leg), enabling efficient heatsinking in constrained layouts.
Key Specifications

IC Role / Device Role / Timing Role: Common-cathode dual diode provides low-loss freewheeling path synchronized with high-side MOSFET switching at 300 kHz. Use Value: 13 mJ EAS rating absorbs energy from parasitic inductance during MOSFET turn-off; 8.0 nH LS reduces ringing and EMI. |
| Telecom Power Supply Freewheeling | Motor Drive Clamping Diode |
|

IC Role / Device Role / Timing Role: Fast-recovery Schottky diode conducting during off-time of primary-side switches, handling repetitive 15 A peak currents. Use Value: 10,000 V/μs dV/dt rating prevents false triggering during rapid voltage transitions; 97 mA IRM at 125 °C ensures stability in sealed enclosures. |
Use Scenario: Mounted across H-bridge motor winding terminals in BLDC driver boards to suppress inductive kickback during PWM commutation. IC Role / Device Role / Timing Role: Bidirectional clamping device absorbing stored inductive energy when MOSFETs switch off abruptly. Use Value: 900 A IFSM surge rating handles worst-case short-circuit transients; TO-262AA package enables direct heatsink mounting for thermal management. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30L25CGY | Same 25 V / 30 A rating, but D2PAK (TO-263AB) package; RthJC = 2.5 °C/W (lower), VF = 0.42 V @ 15 A / 125 °C | Requires PCB layout change due to surface-mount footprint; better thermal performance but no through-hole option | Select when board space permits SMT assembly and lower thermal resistance is prioritized over mechanical robustness |
| ON Semi NTS4101PT1G | Single-die 25 V / 15 A Schottky in SOD-123FL; not dual-anode, no common cathode configuration | Cannot replace VS-32CTQ025-1HM3 in dual-path topologies; limited to single-output or discrete channel use | Only suitable for cost-sensitive, low-current applications where dual-leg functionality is unnecessary |
Compared with STPS30L25CGY and NTS4101PT1G, the VS-32CTQ025-1HM3 uniquely combines AEC-Q101 qualification, TO-262AA through-hole mechanical stability, and true dual-anode common-cathode architecture - making it the only drop-in solution for automotive-grade, high-current, dual-rail power conversion where layout reuse and thermal reliability are mandatory.

FAQ
What is the maximum junction temperature rating for VS-32CTQ025-1HM3?
The VS-32CTQ025-1HM3 has a maximum junction temperature (TJ max.) of +150 °C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive environments where ambient temperatures exceed 105 °C, provided thermal design maintains junction temperature within this limit using the specified RthJC of 3.25 °C/W per leg.
Is VS-32CTQ025-1HM3 pin-compatible with other TO-262 Schottky rectifiers?
VS-32CTQ025-1HM3 follows standard TO-262AA mechanical dimensions and pinout (Anode–Cathode–Anode), matching industry-standard footprints for 3-lead through-hole Schottky rectifiers. However, electrical compatibility requires verification of VR, IF(AV), VF, and thermal specs - e.g., STTH30L06CW uses same package but is a 600 V ultrafast diode, not a Schottky replacement.
Does VS-32CTQ025-1HM3 support lead-free reflow soldering?
Yes, VS-32CTQ025-1HM3 is RoHS-compliant and halogen-free (M3 suffix), qualified for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020 MSL Level 1. Its high-temperature epoxy encapsulation ensures integrity during standard Pb-free reflow profiles without delamination or cracking.
What is the typical reverse leakage current of VS-32CTQ025-1HM3 at 125 °C?
The typical reverse leakage current (IRM) of VS-32CTQ025-1HM3 at 125 °C and rated VR = 25 V is 97 mA, as confirmed in the Electrical Specifications table. This value is significantly lower than generic Schottky diodes at the same temperature, reflecting Vishay's proprietary barrier optimization for high-temperature stability.
How does the common-cathode configuration of VS-32CTQ025-1HM3 benefit power converter design?
The common-cathode configuration of VS-32CTQ025-1HM3 allows both anodes to be independently switched while sharing a single low-inductance cathode return path - simplifying PCB layout in dual-output buck converters and reducing ground loop area. This architecture cuts component count versus two discrete diodes and improves thermal coupling between dies for balanced current sharing.
