Product details

Overview

STPS20L60CGY-TR from STMicroelectronics is an automotive-grade dual center-tap Schottky rectifier in D2PAK package, rated for 2 × 10 A average forward current per diode, 60 V repetitive peak reverse voltage, and 150 °C maximum junction temperature. It delivers low forward voltage drop (0.56 V max at 10 A, 125 °C), negligible switching losses, and specified avalanche capability-designed for high-frequency DC–DC converters and inverters in engine control units and ADAS power stages.

For engineers reviewing the STPS20L60CGY-TR datasheet, STPS20L60CGY-TR pinout, STPS20L60CGY-TR application, or STPS20L60CGY-TR equivalent, key selection criteria include thermal resistance (R_th(j-c) = 1.6 °C/W per diode), surge current rating (220 A, 10 ms), AEC-Q101 qualification, and dual-diode center-tap configuration for synchronous rectification topologies.

Technical Context

This device integrates two independent Schottky diodes sharing a common cathode terminal (center-tap configuration), enabling half-bridge or dual-phase synchronous rectification. Its low VF and absence of minority-carrier storage eliminate reverse recovery charge, making it suitable for >100 kHz switching frequencies in automotive DC–DC modules.

Thermal design relies on conduction cooling via the D2PAK case; junction-to-case resistance is 1.6 °C/W per diode, with coupling resistance of 0.1 °C/W between diodes. Avalanche energy handling (5800 W, 1 µs pulse) supports transient overvoltage robustness in load-dump scenarios per ISO 7637-2.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum reverse blocking voltage per diode; ensures safe operation under automotive load-dump transients up to 60 V.
I_F(AV)	2 × 10 A - Average forward current rating per diode at T_C = 140 °C; supports 20 A total output in dual-phase designs.
V_F (max)	0.56 V @ 10 A, 125 °C - Low conduction loss enables >95% efficiency in 12 V → 5 V/3.3 V buck converters.
R_th(j-c)	1.6 °C/W per diode - Enables direct heatsink mounting; 10 A operation yields ≤16 °C junction-to-case rise above heatsink.
I_FSM	220 A @ 10 ms - Withstands short-circuit events in motor drive gate drivers or battery protection circuits.
AEC-Q101	Qualified - Validated for automotive underhood applications including temperature cycling, HTRB, and ESD testing per stress test plan.

Pinout & Package

Package: D2PAK (TO-263-3), surface-mount, single-row, 3-terminal outline with exposed thermal pad. Dimensions per ST Doc ID 022399 Rev 1: L = 15.0–15.85 mm, W = 10.0–10.4 mm, H = 4.4–4.6 mm; UL94 V0 epoxy; recommended cooling by conduction (method C).

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; connects to high-side switch node in half-bridge topology.
A2	Anode 2	Input terminal for second Schottky diode; used for complementary phase or parallel current sharing.
K	Common Cathode	Shared output node; ties both diodes' cathodes together-enables center-tap output configuration for dual-phase rectification.

Key Features

Feature	Design Value
Low forward voltage drop	V_F ≤ 0.56 V @ 10 A, 125 °C reduces conduction loss by ~30% vs. standard silicon rectifiers in 12 V systems.
Negligible switching losses	No reverse recovery charge (Q_rr = 0) eliminates turn-off loss and EMI in >200 kHz DC–DC stages.
Avalanche capability	5800 W peak avalanche power (1 µs) provides robustness against inductive kickback in solenoid or relay driver circuits.
Thermal resistance	R_th(j-c) = 1.6 °C/W per diode allows direct PCB copper pour heatsinking without external heatsinks in <15 W dissipation designs.

Applications

Engine Control Unit (ECU) Power Supply

ADAS Camera Module DC–DC Converter

Use Scenario: Regulating 12 V battery input to 5 V/3.3 V for microcontroller and sensor rails under wide ambient (-40 to +125 °C).

IC Role / Device Role / Timing Role: Dual Schottky rectifier in synchronous buck converter secondary side; center-tap configuration enables interleaved current sharing.

Use Value: 0.56 V V_F minimizes dropout and thermal rise at 8 A load, supporting AEC-Q100 Grade 2 compliance.

Use Scenario: High-efficiency 12 V → 5 V conversion for CMOS image sensor and ISP in rear-view camera systems.

IC Role / Device Role / Timing Role: Output rectifier in 300 kHz fixed-frequency buck regulator; leverages zero Q_rr to suppress switching noise near analog video signal paths.

Use Value: R_th(j-c) = 1.6 °C/W enables full-load operation without forced air, meeting compact enclosure size constraints.

Electric Power Steering (EPS) Gate Driver Supply

On-Board Charger (OBC) Auxiliary Power

Use Scenario: Isolated auxiliary supply powering MOSFET gate drivers in 3-phase EPS inverter modules.

IC Role / Device Role / Timing Role: Center-tapped rectifier feeding dual 15 V rails for high-side and low-side driver ICs; handles burst-mode load transients.

Use Value: 220 A I_FSM withstands gate charge surges during fault conditions without latch-up or degradation.

Use Scenario: 400 V → 12 V auxiliary supply powering MCU, CAN transceiver, and contactor control in EV on-board chargers.

IC Role / Device Role / Timing Role: Secondary-side rectifier in flyback converter operating at 100–200 kHz; dual-diode layout simplifies transformer center-tap winding.

Use Value: AEC-Q101 qualification ensures reliability across 15-year vehicle lifetime despite repeated thermal cycling in under-hood environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NTS20100CT	V_F = 0.58 V (max @ 10 A, 125 °C); R_th(j-c) = 1.8 °C/W; same D2PAK package.	Lower surge rating (180 A vs. 220 A); not AEC-Q101 qualified-requires additional qualification for automotive use.	Select when cost sensitivity outweighs AEC-Q101 requirement and thermal margin permits higher R_th.
Vishay VS-20CPH06-M3	V_F = 0.62 V (max @ 10 A, 125 °C); R_th(j-c) = 2.0 °C/W; TO-220AC package (through-hole).	Higher V_F increases conduction loss; through-hole mounting limits board density and automated assembly compatibility.	Choose only for legacy through-hole designs where D2PAK rework is prohibited and 0.06 V V_F penalty is acceptable.

Compared with NTS20100CT and VS-20CPH06-M3, STPS20L60CGY-TR offers superior thermal performance (1.6 °C/W), lower forward drop, and built-in AEC-Q101 validation-making it the preferred choice for new automotive power designs requiring production-ready qualification and high-density SMT assembly.

FAQ

What is the thermal derating behavior above 140 °C case temperature?

Per Table 2, I_F(AV) is specified at T_C = 140 °C with duty cycle δ = 0.5. Above this, average current must be linearly derated using R_th(j-c) = 1.6 °C/W and T_j(max) = 150 °C. For example, at T_C = 145 °C, max I_F(AV) drops to ~8.1 A per diode to maintain T_j ≤ 150 °C.

Can STPS20L60CGY-TR be used in non-automotive industrial applications?

Yes-its 150 °C T_j(max), 60 V V_RRM, and robust avalanche rating make it suitable for industrial SMPS, solar microinverters, and telecom power supplies. However, AEC-Q101 qualification does not imply automotive suitability unless system-level requirements (e.g., ISO 16750) are also met.

Is the center-tap configuration internally bonded or externally accessible?

The center tap is the common cathode (K) terminal, physically bonded and externally accessible as a single pin. Anodes A1 and A2 are isolated; no internal connection exists between them-enabling true dual-diode operation in interleaved or phase-split topologies.

How does its surge current rating compare to single-diode equivalents?

At 220 A (10 ms, sinusoidal), STPS20L60CGY-TR matches the surge rating of single-diode 20 A Schottkys (e.g., STPS20L60D). Because each diode shares thermal mass in one package, the dual device maintains identical I_FSM per diode-not doubled-ensuring consistent fault-withstand capability in both configurations.
