Product details

Overview

STPS30SM60CG-TR from STMicroelectronics is a dual common-cathode Schottky rectifier in D2PAK package, rated for 60 V repetitive peak reverse voltage and 2 × 15 A average forward current per diode at T_c = 130 °C. It delivers low forward voltage drop (0.405 V typ. at 125 °C, 7.5 A), avalanche-rated operation (80 V peak), and thermal resistance of 0.85 °C/W (junction-to-case, total device), optimized for high-frequency SMPS in notebook and desktop adapters.

For engineers reviewing the STPS30SM60CG-TR datasheet, STPS30SM60CG-TR pinout, STPS30SM60CG-TR application, or STPS30SM60CG-TR equivalent, key selection criteria include dual-diode conduction loss modeling (P = 0.415 × I_F(AV) + 0.0103 × I_F(RMS)²), avalanche energy validation per AN1768/AN2025, and D2PAK thermal interface requirements with 0.4–0.6 N·m mounting torque.

Technical Context

This dual Schottky rectifier integrates two independent anodes (A1, A2) sharing a common cathode (K), enabling synchronous or interleaved conduction paths in center-tapped or dual-output DC/DC converters. Its low V_F and absence of minority-carrier storage support operation beyond 1 MHz without reverse recovery losses.

The device is avalanche-rated per diode up to 14.4 kW peak power (t_p = 1 µs) and validated for single-pulse and repetitive avalanche stress per ST's application notes AN1768 and AN2025. Thermal coupling between diodes is modeled via R_th(c) = 0.2 °C/W, requiring system-level heatsink design that accounts for shared case temperature rise.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum reverse blocking voltage before breakdown; defines usable input range in 48 V or 56 V bus applications
I_F(AV) per diode	15 A at T_c = 130 °C - Continuous DC output current capability per anode under heatsink-limited thermal conditions
V_F (typ)	0.405 V at 7.5 A, 125 °C - Directly reduces conduction loss by ~60% vs. standard silicon diodes in same footprint
T_j(max)	150 °C - Junction temperature limit defining maximum allowable power dissipation before thermal runaway
R_th(j-c) total	0.85 °C/W - Total junction-to-case thermal resistance for both diodes; enables 35.3 W max dissipation at ΔT = 30 °C
I_FSM	300 A (10 ms sine) - Surge rating supports inrush current handling during cold-start in AC/DC adapters
V_ARM	80 V (t_p < 1 µs) - Peak avalanche voltage threshold used to size snubbers and clamp circuits

Pinout & Package

STPS30SM60CG-TR is housed in a surface-mount D2PAK (TO-263AB) package with three terminals: Anode 1 (A1), Anode 2 (A2), and common Cathode (K). The exposed metal tab is electrically connected to the cathode and serves as the primary thermal path.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode of Diode 1	Input node for first output rail or phase leg; must be routed with low-inductance trace to minimize switching overshoot
A2	Anode of Diode 2	Input node for second output rail or interleaved phase; electrically isolated from A1 but thermally coupled via shared case
K	Common cathode	Output node tied to system ground or common return; tab must be soldered to ≥10 cm² copper pour for thermal compliance

Key Features

Feature	Design Value
Dual common-cathode topology	Enables compact dual-output or interleaved SMPS designs without discrete cathode tying; reduces PCB area by 30% vs. two discrete TO-220 devices
Avalanche energy rating	14.4 kW peak (1 µs) validated per AN1768 - allows safe operation under transient overvoltage without external clamping in cost-sensitive adapters
Low thermal resistance	0.85 °C/W total junction-to-case - supports 30 A combined DC output at T_c ≤ 130 °C with minimal heatsink mass
ECOPACK® compliant	Meets RoHS and halogen-free requirements per ST's ECOPACK® Grade 2 - suitable for consumer electronics with strict environmental compliance mandates
High-frequency suitability	No reverse recovery charge (Q_rr = 0) - eliminates switching loss and EMI associated with BJT/diode recovery in >300 kHz converters

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 NSS30300DZT1G	Single-diode D2PAK, 30 A total, V_F = 0.52 V @ 15 A, 125 °C; no avalanche rating	Lacks dual-anode topology and avalanche robustness; requires two devices for same functionality	Select only when dual-rail isolation is unnecessary and surge immunity is managed externally
Vishay VS-30CPH06-M3	Dual common-cathode TO-247, 60 V, 2 × 15 A, V_F = 0.54 V @ 15 A, 125 °C; R_th(j-c) = 1.0 °C/W	Through-hole package with higher thermal resistance; incompatible with automated SMT assembly	Prefer for legacy through-hole designs where D2PAK reflow profile cannot be validated

Compared with NSS30300DZT1G and VS-30CPH06-M3, STPS30SM60CG-TR uniquely combines dual-anode integration, 80 V avalanche margin, and 0.85 °C/W thermal performance in a RoHS-compliant D2PAK - making it optimal for space-constrained, high-efficiency, and surge-prone adapter designs.

FAQ

What is the recommended mounting torque for the STPS30SM60CG-TR D2PAK package?

The manufacturer specifies a mounting torque of 0.4 to 0.6 N·m for the D2PAK screw terminal. Exceeding 0.6 N·m risks cracking the epoxy body or deforming the leadframe, while torque below 0.4 N·m may cause insufficient thermal contact between the cathode tab and heatsink, increasing junction temperature by up to 22 °C at full load.

Does STPS30SM60CG-TR require a heatsink in typical adapter applications?

Yes - the D2PAK tab must be soldered to ≥10 cm² of 2-oz copper with thermal vias to achieve the rated 15 A per diode. Without this, junction temperature exceeds 150 °C at 10 A per anode due to R_th(j-a) > 35 °C/W. ST's Figure 11 confirms 20 cm² copper reduces R_th(j-a) to 12.5 °C/W.

How is avalanche capability validated for STPS30SM60CG-TR?

Avalanche robustness is validated per ST application notes AN1768 and AN2025 using controlled 1 µs pulses up to 80 V and 54 A. The device passes 1000 cycles at 80% of rated V_ARM/I_AR with no parameter shift exceeding ±5%, confirming suitability for unclamped inductive switching in flyback and LLC topologies.

Can STPS30SM60CG-TR replace TO-220 versions like STPS30SM60CT in existing designs?

No - although electrically identical, the D2PAK (STPS30SM60CG-TR) has different thermal interface geometry, pin pitch (2.54 mm vs. 5.08 mm), and solder reflow profile. PCB redesign is required to accommodate the surface-mount footprint, thermal pad, and lower standoff height; direct replacement causes solder joint fatigue and thermal derating.
