Product details
Overview
VS-32CTQ030-1HM3 from Vishay Semiconductors is a high-performance dual common-cathode Schottky rectifier rated for 30 V reverse voltage and 2 × 15 A average forward current per leg, with 0.40 V forward voltage at 15 A and 125 °C junction temperature. It operates reliably up to 150 °C TJ, features 13 mJ non-repetitive avalanche energy, and is AEC-Q101 qualified for automotive-grade power conversion.
For engineers reviewing the VS-32CTQ030-1HM3 datasheet, VS-32CTQ030-1HM3 pinout, VS-32CTQ030-1HM3 application, or VS-32CTQ030-1HM3 equivalent, key selection criteria include its TO-262AA package thermal resistance (3.25 °C/W per leg), low 9.09 mΩ forward slope resistance, and suitability for high-frequency freewheeling and reverse battery protection in harsh-environment DC/DC converters.
Technical Context
This dual-diode Schottky rectifier uses proprietary barrier technology to minimize reverse leakage at elevated temperatures-97 mA typical IRM at 125 °C and rated VR-enabling stable operation in automotive under-hood power supplies. Its common-cathode configuration supports synchronous rectification topologies where shared cathode routing simplifies PCB layout and reduces parasitic inductance.
The device delivers high surge robustness (900 A IFSM, 5 μs sine) and fast switching performance (10,000 V/μs dV/dt), supported by low 8.0 nH typical series inductance per leg and 1300 pF junction capacitance at 5 V. Thermal design is facilitated by a low RthJC of 3.25 °C/W per leg and compatibility with standard heatsink mounting (0.50 °C/W RthCS).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 30 V maximum DC reverse voltage - defines safe blocking capability in 24 V automotive systems with transient margin. |
| IF(AV) | 2 × 15 A average forward current - supports dual-leg 30 A total conduction in continuous-duty power stages. |
| VFM | 0.40 V at 15 A, 125 °C - enables <1.2 W conduction loss per leg at high ambient, critical for thermally constrained designs. |
| TJ max | 150 °C - allows operation in under-hood environments without derating below full current rating. |
| EAS | 13 mJ non-repetitive avalanche energy - provides robustness against inductive turn-off transients in motor drive or converter freewheeling. |
| RthJC | 3.25 °C/W per leg - enables efficient heat transfer to heatsink, supporting >20 W dissipation per die with ≤65 °C case rise. |
| IRM typ. | 97 mA at 125 °C, rated VR - ensures minimal leakage-induced power loss and thermal runaway risk in high-temp battery protection circuits. |
Pinout & Package
VS-32CTQ030-1HM3 is housed in the TO-262AA (also known as modified TO-262) surface-mount package with three terminals: two anodes and one common cathode. The package features a thermally enhanced leadframe, halogen-free RoHS-compliant termination (M3 suffix), and AEC-Q101 qualification for automotive reliability.
| Pin/Terminal | Circuit Role | Design Meaning |

Use Scenario: 12 V–48 V bidirectional DC/DC converter in 48 V mild hybrid vehicles, operating continuously at 85 °C ambient. IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacing MOSFETs in secondary side, leveraging low VF and zero recovery time. Use Value: 0.40 V VFM at 125 °C reduces conduction loss by ~35% vs. comparable Si diodes, lowering thermal load on heatsink and enabling smaller enclosure. |
Use Scenario: IGBT-based 3-phase inverter driving HVAC compressors in factory automation equipment. IC Role / Device Role / Timing Role: Freewheeling path across each phase leg during PWM dead-time, clamping inductive kickback. Use Value: 13 mJ EAS withstands repetitive inductive spikes without degradation; 10,000 V/μs dV/dt prevents false triggering during fast voltage transitions. |
| Reverse Battery Protection | High-Frequency SMPS Secondary Rectification |
|
Use Scenario: Input protection circuit in automotive infotainment head unit powered from vehicle battery with polarity reversal risk. IC Role / Device Role / Timing Role: Common-cathode configured as OR-ing diode, blocking reverse current while passing forward current with minimal drop. Use Value: 0.40 V forward drop at 15 A limits power dissipation to <6 W, avoiding thermal shutdown during sustained 20 A load conditions. |
Use Scenario: Output rectification in 300 kHz LLC resonant converter for server power supply with tight efficiency targets. IC Role / Device Role / Timing Role: High-frequency rectifier in synchronous topology, minimizing switching losses and EMI generation. Use Value: 1300 pF CT and 8.0 nH LS per leg reduce ringing and improve EMI compliance; low IRM prevents leakage-induced standby power waste. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3030CGY | Same 30 V VR, 30 A IF(AV), but D2PAK (TO-263AB) package; RthJC = 2.5 °C/W, higher VF (0.52 V @ 15 A, 125 °C). | Preferred where board space permits larger footprint and lower thermal resistance is prioritized over mounting height. | Select STPS3030CGY only if heatsinking is optimized for D2PAK and layout accommodates wider pad spacing. |
| ON Semi MBR3030CT | 30 V VR, 30 A IF(AV), TO-220AC package; VF = 0.55 V @ 15 A, 125 °C; no AEC-Q101 qualification; RthJC = 2.0 °C/W. | Suitable for industrial non-automotive use; lacks automotive reliability validation and has higher conduction loss. | Choose MBR3030CT for cost-sensitive industrial SMPS where AEC-Q101 is not required and TO-220 mounting is acceptable. |
Compared with STPS3030CGY and MBR3030CT, the VS-32CTQ030-1HM3 offers superior high-temperature leakage control (97 mA IRM vs. >200 mA), AEC-Q101 qualification, and TO-262AA's lower profile-making it optimal for automotive modules with strict height constraints and thermal cycling requirements.

FAQ
What is the maximum junction temperature rating for VS-32CTQ030-1HM3?
The VS-32CTQ030-1HM3 is rated for a maximum junction temperature (TJ max) of +150 °C. This specification is validated per Vishay's characterization and enables full 2 × 15 A current delivery without derating in high-ambient environments such as automotive under-hood applications. The device maintains stable forward voltage and low leakage up to this limit, as confirmed in the 95774 datasheet Figure 2 and Absolute Maximum Ratings table.
Is VS-32CTQ030-1HM3 pin-compatible with VS-32CTQ030SHM3?
No, VS-32CTQ030-1HM3 is not pin-compatible with VS-32CTQ030SHM3. The former uses the TO-262AA package with a 3-pin straight-lead configuration, while the latter uses the D2PAK (TO-263AB) package with gull-wing leads. Pin assignments differ: TO-262AA pins are Anode 1–Cathode–Anode 2 in-line; D2PAK places Cathode on the center tab and Anodes on outer leads. Layout redesign is required for substitution.
Does VS-32CTQ030-1HM3 meet automotive qualification standards?
Yes, VS-32CTQ030-1HM3 is AEC-Q101 qualified and meets JESD201 Class 1A whisker test requirements. It also complies with MSL Level 1 per J-STD-020 (peak reflow temperature 260 °C) and is halogen-free/RoHS-compliant (M3 suffix). These qualifications are explicitly stated in the "FEATURES" section of document 95774 and verified in Vishay's material categorization documentation.
What is the typical reverse leakage current of VS-32CTQ030-1HM3 at 125 °C?
The typical reverse leakage current (IRM) of VS-32CTQ030-1HM3 at 125 °C and rated VR is 97 mA, as specified in the Electrical Specifications table of document 95774. This value reflects the device's optimized barrier technology for high-temperature stability and is significantly lower than generic Schottky diodes, which often exceed 200 mA under identical conditions.
What thermal resistance does VS-32CTQ030-1HM3 exhibit from junction to case?
VS-32CTQ030-1HM3 has a maximum thermal resistance of 3.25 °C/W per leg from junction to case (RthJC), measured under DC operation per Figure 4 in document 95774. This value applies to each of the two integrated Schottky dies independently and assumes proper mounting to a heatsink with thermal grease (RthCS = 0.50 °C/W typical).
