Product details
Overview
STPS30M100DJF-TR from STMicroelectronics is a 100 V, 30 A average forward current power Schottky rectifier in PowerFLAT™ 5x6 package, featuring 0.66 V typical forward voltage at 30 A and 125 °C, 2.5 °C/W junction-to-case thermal resistance, and 200 A non-repetitive surge capability-optimized for high-efficiency SMPS and DC/DC converters in space-constrained desktop power supplies and LED lighting.
For engineers reviewing the STPS30M100DJF-TR datasheet, STPS30M100DJF-TR pinout, STPS30M100DJF-TR application, or STPS30M100DJF-TR equivalent, key selection criteria include low conduction loss (P ≈ 0.65×IF(AV) + 0.00267×IF²(RMS)), high avalanche energy rating (1080 W at 10 µs), and thermal performance under forced-air or PCB-copper heatsinking per AN5046.
Technical Context
This Schottky rectifier uses a planar metal-silicon junction optimized for high-frequency switching, with minimal reverse recovery charge (Qrr ≈ 0 nC) and low junction capacitance (≈1000 pF at 30 V). Its 150 °C maximum junction temperature and 100 µA reverse leakage at 25 °C support stable operation across industrial ambient ranges.
The PowerFLAT™ 5x6 package enables direct thermal coupling to PCB copper planes, achieving Rth(j-a) as low as 4.5 °C/W with 10 cm² copper area (FR4, 35 µm), while maintaining ultra-low profile (1.0 mm max height) for slim adapter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 30 A - supports continuous output current in 100–200 W DC/DC stages without active cooling |
| VRRM | 100 V - rated for primary-side synchronous rectification in 48 V input systems or secondary-side use up to 85 V DC bus |
| VF (typ.) | 0.66 V @ 30 A, 125 °C - reduces conduction loss to ~20 W at full load, enabling >94% efficiency in 12 V/25 A outputs |
| Rth(j-c) | 2.5 °C/W - allows direct mounting to copper pour for thermal management without external heatsink |
| IFSM | 200 A @ 10 ms - withstands inrush and transient overloads in AC-DC front-end and hot-swap circuits |
| PARM | 1080 W @ 10 µs, Tj = 125 °C - provides robust single-pulse avalanche energy handling during voltage spikes |
Pinout & Package
Package: PowerFLAT™ 5x6 (STMicroelectronics trademark), surface-mount, thermally enhanced epoxy package with exposed cathode pad (bottom side), UL 94 V0 compliant, 0.8–1.0 mm height, 5.9 × 6.35 mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (2 pins, top-side) | Current entry point | Parallel anode terminals reduce bond wire inductance and resistive drop; designed for low-inductance PCB routing |
| Cathode (exposed pad, bottom) | Current exit / thermal path | Large copper-exposed pad serves dual role: low-resistance current return and primary thermal conduction path to PCB |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high Tj | 0.66 V typ. @ 30 A, 125 °C - maintains efficiency under thermal stress in enclosed adapters |
| High avalanche rating | 1080 W peak avalanche power - eliminates need for external clamping in flyback snubberless designs |
| Thermal resistance | Rth(j-c) = 2.5 °C/W - enables >30 W dissipation with <75 °C temperature rise above case |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant materials - meets EU environmental directives without performance trade-off |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH01-M3/45 | Same 100 V/30 A rating but TO-220AC package; VF = 0.72 V @ 30 A, 125 °C; Rth(j-c) = 3.0 °C/W | Requires heatsink and vertical mounting; unsuitable for ultra-low-profile designs | Prefer when legacy through-hole assembly or higher surge margin (250 A IFSM) is prioritized over board space |
| ON Semiconductor MBR30100CT | TO-220AB dual common-cathode; VF = 0.85 V @ 30 A, 25 °C; no specified avalanche rating | Lacks avalanche capability and high-Tj VF data; higher conduction loss at elevated temperature | Select only for cost-sensitive, non-avalanche-critical 25 °C ambient applications with ample heatsinking |
Compared with VS-30CPH01-M3/45 and MBR30100CT, STPS30M100DJF-TR delivers superior thermal performance in surface-mount layouts, lower conduction loss at operating temperature, and verified avalanche ruggedness-making it optimal for modern compact, high-efficiency SMPS where board area and thermal headroom are constrained.

FAQ
What is the recommended PCB layout for optimal thermal performance?
Per AN5046, use ≥10 cm² of 35 µm copper on the bottom layer connected directly to the exposed cathode pad via ≥4 thermal vias (0.3 mm diameter, 0.8 mm pitch). Avoid solder mask over the pad and ensure minimum 0.5 mm clearance to adjacent traces to prevent solder wicking.
Does STPS30M100DJF-TR support synchronous rectification control?
No-it is a passive Schottky rectifier, not a controlled MOSFET-based synchronous rectifier. It operates unidirectionally with zero gate drive requirement, making it compatible with all flyback, forward, and LLC topologies without timing or control circuitry.
How is avalanche capability validated for this part?
Avalanche energy is characterized per JEDEC JESD24-11, with PARM = 1080 W measured at tp = 10 µs, Tj = 125 °C, using repetitive unclamped inductive switching (UIS) tests. The rating is guaranteed across the full operating temperature range and does not require derating below 125 °C.
Can STPS30M100DJF-TR replace a standard silicon diode in an existing design?
Yes-if the original diode is rated ≤100 V and ≤30 A average current. Due to its lower VF and zero Qrr, it reduces conduction and switching losses, but requires verifying PCB thermal relief, solder paste volume (PowerFLAT™ needs precise stencil aperture), and absence of voltage overshoot exceeding 100 V during turn-off.
