Product details

Overview

STPS15H100CBY-TR from STMicroelectronics is an AEC-Q101 qualified dual-center-tab Schottky rectifier in DPAK package, rated for 100 V repetitive reverse voltage and 2 × 7.5 A average forward current per diode, with max forward voltage drop of 0.67 V at 125 °C and 7.5 A - optimized for high-frequency LED headlamp circuits in automotive power supplies.

For engineers reviewing the STPS15H100CBY-TR datasheet, STPS15H100CBY-TR pinout, STPS15H100CBY-TR application, or STPS15H100CBY-TR equivalent, key selection criteria include avalanche capability (475 W, 10 µs), low thermal resistance (R_th(j-c) = 2.4 °C/W total), negligible switching losses, and automotive-grade reliability under T_j up to 175 °C.

Technical Context

This dual-diode Schottky rectifier integrates two independent anode-cathode junctions sharing a common center tab (K) for thermal and mechanical stability. Its low V_F–I_F trade-off minimizes conduction loss while maintaining sub-4 mA reverse leakage at 125 °C and 100 V.

The device features specified avalanche capability (P_ARM = 475 W at t_p = 10 µs, T_j = 125 °C) and thermal coupling between diodes quantified by R_th(c) = 0.7 °C/W, enabling accurate junction temperature prediction in dual-channel operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - supports input stages in 48 V and 60 V automotive systems with margin against transients.
I_F(AV)	2 × 7.5 A - enables dual-channel 15 A total DC output with shared heatsink via center tab.
V_F(max)	0.67 V @ 7.5 A, 125 °C - reduces conduction loss to ~5.0 W per diode at rated current.
R_th(j-c)	2.4 °C/W total - allows ≤42 W power dissipation before reaching 175 °C junction limit at 25 °C case.
I_R(max)	4 mA @ 125 °C, V_RRM - ensures minimal standby power loss in always-on automotive lighting modules.
P_ARM	475 W @ 10 µs - withstands load-dump and ISO 7637-2 pulse 5a without failure.
T_j(max)	175 °C - meets under-hood thermal requirements for front-end lighting control units.

Pinout & Package

Package: DPAK (TO-252), surface-mount, single-center-tab configuration with three terminals: two anodes (A1, A2) and one shared cathode (K). The center tab (K) serves as both electrical cathode connection and primary thermal path to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first Schottky diode; connects to high-side switch node in synchronous buck or flyback secondary.
A2	Anode 2	Input terminal for second independent Schottky diode; enables dual-output or phase-interleaved DC/DC designs.
K	Common Cathode / Thermal Tab	Output node for both diodes; soldered directly to large copper pour for <2.4 °C/W thermal resistance to PCB.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive use including temperature cycling, humidity, and mechanical shock per JESD47.
Negligible switching losses	No minority-carrier storage delay - enables >1 MHz operation without reverse recovery loss penalty.
Low thermal resistance	R_th(j-c) = 2.4 °C/W total - permits 42 W combined dissipation with ≤150 °C ΔT from case to junction.
Specified avalanche capability	475 W peak power for 10 µs pulses - protects against inductive kickback in LED driver inductor circuits.
Good V_F/I_R trade-off	0.67 V @ 7.5 A / 4 mA @ 125 °C - balances efficiency and leakage in thermally constrained headlamp modules.

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 NTS2501MH	Single-diode DPAK, 100 V/15 A, R_th(j-c) = 3.0 °C/W, no avalanche rating.	Lacks dual-anode structure and avalanche specification - unsuitable for fault-tolerant automotive lighting.	Select only for cost-sensitive non-automotive DC/DC where dual-channel isolation is unnecessary.
Vishay VS-15CTH10-M3	Dual-diode TO-220AC, 100 V/15 A, R_th(j-c) = 2.0 °C/W, but through-hole, no AEC-Q101.	Requires mounting hardware and larger PCB area; not qualified for automotive vibration or thermal cycling.	Prefer for industrial bench power supplies where surface-mount constraints and automotive compliance are not required.

Compared with NTS2501MH and VS-15CTH10-M3, STPS15H100CBY-TR uniquely combines AEC-Q101 qualification, dual-anode DPAK packaging, 475 W avalanche rating, and 2.4 °C/W thermal resistance - making it the only option qualified for under-hood LED headlamp rectification in production vehicles.

FAQ

What is the maximum continuous junction temperature for STPS15H100CBY-TR?

The absolute maximum operating junction temperature is 175 °C, validated per AEC-Q101 stress testing. Derating begins at T_c = 145 °C for full 15 A device current, and thermal design must ensure R_th(j-a) remains below 70 °C/W on 40 cm² copper to maintain safe operation at 85 °C ambient.

Does STPS15H100CBY-TR support PPAP documentation for automotive programs?

Yes - STPS15H100CBY-TR is PPAP-capable per AIAG standards. ST provides full Level 3 PPAP packages including dimensional reports, material certifications, process flow diagrams, control plans, and initial process capability studies (C_pk ≥ 1.33) upon request for qualified automotive customers.

How is thermal coupling managed between the two diodes in this dual package?

Thermal coupling is quantified by R_th(c) = 0.7 °C/W: when both diodes conduct simultaneously, junction temperature rise of Diode 1 equals P₁ × 4 °C/W + P₂ × 0.7 °C/W. This measured coupling enables accurate multi-diode thermal modeling without assuming fully independent dies.

Can STPS15H100CBY-TR replace standard silicon diodes in existing 100 V designs?

Yes - its 100 V V_RRM, DPAK footprint, and pin-compatible layout allow direct substitution for legacy 100 V silicon rectifiers. However, forward voltage drops below 0.7 V reduce conduction loss by ~30%, requiring verification of reduced thermal stress on adjacent components and PCB copper.
