Product details

Overview

STPS10H100CG from STMicroelectronics is a dual high-voltage Schottky barrier rectifier in D2PAK package, rated for 100 V repetitive peak reverse voltage, 5 A average forward current per diode (10 A total), and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.61 V max at 125 °C, 5 A), low leakage (<4.5 mA at 125 °C, 100 V), and avalanche-rated power (7200 W peak) - optimized for compact, high-efficiency DC/DC converters in confined thermal environments.

For engineers reviewing the STPS10H100CG datasheet, STPS10H100CG pinout, STPS10H100CG application, or STPS10H100CG equivalent, key selection criteria include thermal resistance (2.2 °C/W junction-to-case per diode), dV/dt rating (10,000 V/µs), surge capability (180 A non-repetitive), and dual-diode configuration enabling synchronous or interleaved converter topologies with shared heatsink mounting.

Technical Context

This dual Schottky rectifier integrates two independent 100 V, 5 A diodes in a single D2PAK thermally enhanced package. Its low VF and negligible reverse recovery enable operation at high switching frequencies (>100 kHz) without snubbers, reducing conduction and switching losses in isolated flyback and forward converters.

The device features specified avalanche energy handling (7200 W peak, 1 µs pulse), validated junction-to-case thermal resistance (2.2 °C/W per diode), and stable leakage performance up to 125 °C - critical for unventilated AC-DC adapters and on-board point-of-load supplies where thermal derating margins are tight.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	100 V - supports input rectification in 48 V–96 V industrial DC bus systems and universal-input offline SMPS with margin against line transients.
IF(AV) per diode	5 A - enables 10 A total continuous output current in dual-phase or parallel configurations with proper thermal management.
VF (max)	0.61 V at Tj = 125 °C, IF = 5 A - reduces conduction loss to ~3.05 W per diode at full load, minimizing heatsink requirements.
Rth(j-c) per diode	2.2 °C/W - allows direct mounting to PCB copper pour or small heatsink; 11 °C rise at 5 A dissipation.
IRRM	1 A at VR = 100 V, tp = 2 µs - ensures stable blocking under fast transient conditions without false triggering of protection circuits.
dV/dt	10,000 V/µs - prevents spurious turn-on during high-slew-rate switching node transitions in hard-switched topologies.
Tj(max)	175 °C - permits operation in sealed enclosures or high-ambient environments (e.g., automotive under-hood auxiliary supplies).

Pinout & Package

D2PAK (TO-263) package: thermally optimized surface-mount outline with exposed metal tab (pin K) for low-thermal-resistance heatsinking. Three terminals: A1 and A2 (anodes), K (common cathode). Mounting requires soldering the tab to ≥10 cm² of 35 µm copper on FR4 for Rth(j-a) ≈ 15 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; connects to primary-side switch node in synchronous rectification or secondary winding in center-tapped topology.
A2	Anode 2	Input terminal for second independent Schottky diode; enables dual-output or interleaved secondary rectification without cross-conduction risk.
K	Common Cathode	Shared output node; must be routed with low-inductance, high-current trace to minimize voltage overshoot during diode commutation.

Key Features

Feature	Design Value
High junction temperature capability	Rated for continuous operation at 175 °C junction - eliminates need for oversized heatsinks in space-constrained 5–20 W adapters.
Low leakage at elevated temperature	≤4.5 mA at 125 °C and 100 V reverse bias - maintains efficiency and stability in high-ambient industrial control modules.
Avalanche energy rating	7200 W peak (1 µs pulse) - withstands inductive kickback in poorly damped transformer designs without degradation.
Low static and dynamic losses	VF ≤ 0.61 V + negligible Qrr - eliminates reverse recovery loss, enabling >92% efficiency in 500 kHz DC/DC converters.
Dual-diode integration	Two electrically isolated 5 A diodes in one D2PAK - reduces board area by 40% vs. discrete TO-220 solutions and improves thermal coupling uniformity.

Applications

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
Vishay VS-10ETH02-M3	100 V, 10 A total, VF = 0.65 V max @ 125 °C; Rth(j-c) = 2.5 °C/W; TO-263AB package.	Higher VF increases conduction loss by ~0.25 W per diode at 5 A; slightly lower thermal performance limits power density.	Select when legacy layout uses identical footprint but requires tighter IR tolerance (IRRM = 0.5 A max).
ON Semiconductor MBR10100CT	100 V, 10 A total, VF = 0.75 V max @ 125 °C; Rth(j-c) = 3.0 °C/W; TO-220 package.	Higher VF and thermal resistance raise junction temperature by ~18 °C at same load; through-hole mounting increases assembly cost.	Choose only for through-hole prototyping or where D2PAK reflow compatibility is unavailable.

Compared with VS-10ETH02-M3 and MBR10100CT, STPS10H100CG offers the lowest VF and best thermal resistance among 100 V dual Schottky rectifiers in surface-mount packages, directly enabling higher power density and smaller heatsinks in thermally constrained designs.

FAQ

What is the maximum continuous forward current per diode for STPS10H100CG at 165 °C case temperature?

The STPS10H100CG is rated for 5 A average forward current per diode at Tc = 165 °C in D2PAK package, as confirmed in the Absolute Ratings table. This value assumes δ = 0.5 duty cycle and proper PCB copper area (≥10 cm²) for thermal conduction. Exceeding this current without additional heatsinking risks junction temperature exceeding 175 °C.

Does STPS10H100CG support avalanche energy handling, and how is it specified?

Yes - STPS10H100CG has a specified repetitive peak avalanche power of 7200 W at Tj = 25 °C with 1 µs pulse duration. This is validated per ST's internal qualification and documented in the Absolute Ratings section. The device is not intended for sustained avalanche operation but can safely absorb short-duration inductive energy spikes common in flyback transformer reset.

Can STPS10H100CG be used in parallel with another unit for higher current capacity?

No - STPS10H100CG contains two diodes in one package with shared thermal path and common cathode; paralleling multiple STPS10H100CG units is not recommended due to mismatched VF drift with temperature and uneven current sharing. For >10 A, use a single higher-rated part like STPS20H100CG or implement external current-balancing resistors with derated total current.

What is the recommended minimum copper area for the D2PAK tab on FR4 PCB?

STMicroelectronics recommends ≥10 cm² of 35 µm copper on the component side beneath the D2PAK tab to achieve Rth(j-a) ≈ 15 °C/W, as shown in Figure 10 of the datasheet. Using less than 5 cm² raises thermal resistance above 25 °C/W, risking junction temperature exceedance at full load without forced air cooling.
