Product details
Overview
STPS40150CGY-TR from STMicroelectronics is a dual-center-tab D²PAK-packaged Schottky rectifier with 150 V reverse voltage rating, 2 × 20 A average forward current per diode, and 0.69 V typical forward voltage at 125 °C - engineered for automotive DC/DC converters and high-frequency SMPS where low conduction loss and thermal robustness are critical.
For engineers reviewing the STPS40150CGY-TR datasheet, STPS40150CGY-TR pinout, STPS40150CGY-TR application, or STPS40150CGY-TR equivalent, key selection factors include junction-to-case thermal resistance (1.2 °C/W per diode), AEC-Q101 qualification, 175 °C max operating temperature, and dual-diode configuration enabling interleaved or phase-split rectification in compact power stages.
Technical Context
This dual Schottky rectifier integrates two independent 150 V / 20 A diodes in a single D²PAK package with shared center tab for thermal coupling and mechanical stability. Its low VF (0.69 V typ. @ 20 A, 125 °C) and low Rth(j-c) (1.2 °C/W per diode) enable high-efficiency operation in automotive-grade 12 V–48 V DC/DC topologies.
The device supports high-frequency switching up to several hundred kHz due to low junction capacitance (~500 pF @ 30 V) and negligible reverse recovery charge. It is rated for surge current up to 250 A (10 ms sine half-cycle) and avalanche energy handling (1080 W peak, 10 µs pulse), making it suitable for transient-heavy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Withstands repetitive reverse voltage up to 150 V without breakdown; enables use in 48 V automotive bus-derived converters. |
| IF(AV) per diode | 20 A - Sustains continuous forward current of 20 A per diode at TC = 150 °C; supports 40 A total device output with proper heatsinking. |
| VF(typ.) | 0.69 V @ 20 A, 125 °C - Low conduction loss reduces power dissipation and improves efficiency in high-current, thermally constrained layouts. |
| Rth(j-c) per diode | 1.2 °C/W - Enables direct thermal path from junction to case; allows precise thermal design when mounted on copper heatsink or PCB pad. |
| Tj(max) | 175 °C - Rated for extended operation in under-hood automotive environments; exceeds standard industrial temperature limits. |
| IR(max) | 17 mA @ 125 °C, VR = VRRM - Low leakage preserves efficiency at elevated temperatures and minimizes standby losses. |
| IFSM | 250 A @ 10 ms sine - Handles short-duration load dumps and inrush events common in vehicle electrical systems. |
Pinout & Package
D²PAK (TO-263AB) package with exposed center tab for thermal and mechanical anchoring; 3-pin configuration: Pin 1 (Anode 1), Pin 2 (Cathode common), Pin 3 (Anode 2). The center tab is electrically connected to cathode and serves as primary thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (A1) | Anode of Diode 1 | Input terminal for first rectifying path; routed separately to avoid cross-conduction in dual-phase designs. |
| Pin 2 (K) | Common Cathode | Shared output node for both diodes; electrically tied to center tab for low-inductance, low-resistance return path. |
| Pin 3 (A2) | Anode of Diode 2 | Input terminal for second rectifying path; enables symmetrical layout in interleaved or dual-output topologies. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NTS4101PT1G | Single-diode 150 V / 20 A D²PAK; no dual configuration; Rth(j-c) = 1.5 °C/W. | Requires two devices for dual-path operation; higher thermal resistance increases board area and heatsink cost. | Choose only if discrete layout flexibility outweighs integration benefit and thermal penalty. |
| Vishay VS-40CPH015 | 150 V / 40 A single-diode TO-247; VF = 0.82 V @ 20 A, 125 °C; Rth(j-c) = 0.9 °C/W. | Larger footprint and higher VF increase conduction loss; not AEC-Q101 qualified. | Select only for non-automotive industrial use where space is less constrained and qualification is not required. |
Compared with NTS4101PT1G and VS-40CPH015, STPS40150CGY-TR uniquely delivers dual-diode integration, AEC-Q101 compliance, and lowest VF in its class - making it optimal for space- and thermal-constrained automotive DC/DC where reliability and efficiency are co-prioritized.

FAQ
Is STPS40150CGY-TR pin-compatible with STPS40150C-Y?
Yes - STPS40150CGY-TR and STPS40150C-Y share identical D²PAK package dimensions, pinout (A1–K–A2), and thermal pad configuration. The "-TR" suffix denotes tape-and-reel packaging (1000 pcs), while "-Y" indicates tube packaging; electrical and thermal performance are fully identical.
What is the recommended minimum copper area for the center tab on FR4 PCB?
Per DS12474 Figure 7, a minimum 25 cm² of 35 µm-thick copper on the component side is recommended to achieve Rth(j-a) ≤ 25 °C/W. For automotive applications, ST recommends ≥35 cm² with internal plane coupling to maintain Tj ≤ 150 °C at full 40 A load.
Does STPS40150CGY-TR support synchronous rectification control?
No - this is a passive Schottky rectifier with fixed anode-cathode polarity. It does not integrate gate drive or control logic. For synchronous rectification, external MOSFETs and dedicated controllers (e.g., STSR3) must be used in conjunction with this device as a reference or backup path.
How does the dual-diode configuration affect thermal coupling between channels?
Thermal coupling occurs via the shared center tab and internal die substrate. Table 2 specifies Rth(c) = 0.5 °C/W coupling resistance. When both diodes conduct simultaneously, junction temperature rise of Diode 1 includes self-heating plus 50% of Diode 2's power - requiring derating to 17 A per diode at full load for safe 175 °C operation.
