Product details
Overview
VS-30CTQ040STRLHM3 from Vishay Semiconductors is a high-performance dual-anode Schottky rectifier in D2PAK (TO-263AB) package, rated for 40 V reverse voltage and 30 A average forward current (2 × 15 A per leg), with 0.56 V forward voltage at 15 A and 125 °C junction temperature. It serves as a low-loss freewheeling or output rectifier in automotive-grade DC/DC converters and industrial switching power supplies.
For engineers reviewing the VS-30CTQ040STRLHM3 datasheet, VS-30CTQ040STRLHM3 pinout, VS-30CTQ040STRLHM3 application, or VS-30CTQ040STRLHM3 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C maximum junction temperature, center-tap common-cathode configuration, and tape-and-reel packaging for automated SMT assembly.
Technical Context
This device integrates two independent Schottky die in a single D2PAK package with shared cathode terminal, enabling synchronous rectification or dual-output configurations without external parallel diodes. Its proprietary barrier technology ensures stable operation up to 175 °C while maintaining low VF and moderate IRM.
The VS-30CTQ040STRLHM3 supports high-frequency switching (dV/dt = 10,000 V/μs) and delivers 20 mJ non-repetitive avalanche energy per leg - critical for inductive load handling in motor drives and automotive power modules. Thermal resistance is specified at 3.25 °C/W (junction-to-case per leg) under DC conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3045CGY-TR | 45 V VR, same 30 A IF(AV), but TO-220AC package (through-hole), no AEC-Q101 qualification | Preferred for legacy through-hole industrial PSUs; lacks automotive qualification and SMT thermal performance | Select when board-level rework tolerance is required or AEC-Q101 is not mandated |
| SS3040H | 40 V VR, 30 A IF(AV), DO-201AD package, VF = 0.70 V @ 15 A/125 °C, no avalanche rating | Suitable for cost-sensitive consumer adapters; limited thermal dissipation and no automotive validation | Choose only for non-automotive, low-power-density applications where footprint and qualification are secondary |
Compared with STPS3045CGY-TR and SS3040H, the VS-30CTQ040STRLHM3 uniquely combines AEC-Q101 qualification, D2PAK thermal performance (3.25 °C/W), and 0.56 V VF at 125 °C - making it the only option qualified for under-hood automotive use with high-efficiency SMT implementation.

FAQ
What is the maximum junction temperature rating for the VS-30CTQ040STRLHM3?
The VS-30CTQ040STRLHM3 has a maximum junction temperature (TJ max.) of +175 °C, verified per AEC-Q101 stress testing and supported by its high-purity epoxy encapsulation and guard ring structure. This rating allows uninterrupted operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105 °C. The VS-30CTQ040STRLHM3 maintains stable forward voltage and leakage characteristics across this full range.
Is the VS-30CTQ040STRLHM3 qualified for automotive applications?
Yes, the VS-30CTQ040STRLHM3 is AEC-Q101 qualified and meets JESD-201 Class 1A whisker test requirements. It also complies with MSL Level 1 per J-STD-020 and features halogen-free, RoHS-compliant, Pb-free terminations (M3 suffix). These qualifications confirm its suitability for automotive powertrain, body electronics, and ADAS systems - unlike generic industrial Schottky rectifiers that lack formal automotive validation.
What does the "STRLHM3" suffix indicate in VS-30CTQ040STRLHM3?
The "STRLHM3" suffix identifies the VS-30CTQ040STRLHM3 as a tape-and-reel packaged part (STRL) in left-oriented reel configuration for D2PAK devices, with AEC-Q101 qualification (H) and halogen-free/RoHS/Pb-free compliance (M3). This distinguishes it from tube-packaged variants (e.g., VS-30CTQ040SHM3) and confirms compatibility with automated SMT assembly lines requiring standardized reel orientation and automotive-grade material compliance.
How does the center-tap configuration of the VS-30CTQ040STRLHM3 benefit power supply design?
The VS-30CTQ040STRLHM3 uses a center-tap common-cathode configuration with two independent anodes (Pins 1 and 3) and one shared cathode (Pin 2). This enables dual-output buck converters, interleaved topologies, or redundant freewheeling paths - all within a single D2PAK footprint. Unlike discrete diodes, the matched die characteristics ensure symmetrical VF, thermal coupling, and current sharing, reducing layout complexity and improving system-level reliability.
What is the avalanche energy rating of the VS-30CTQ040STRLHM3, and why does it matter?
The VS-30CTQ040STRLHM3 delivers 20 mJ non-repetitive avalanche energy (EAS) per leg at TJ = 25 °C, measured with IAS = 3.0 A and L = 4.40 mH. This rating directly supports robustness in motor drive and solenoid control applications where inductive turn-off transients exceed normal blocking voltage. Without this specification, unprotected diodes risk cumulative degradation or catastrophic failure during repeated switching events - a key differentiator for industrial and automotive motion control.
