Product details
Overview
STPS30H100DJF-TR from STMicroelectronics is a 100 V, 30 A average forward current Schottky rectifier in PowerFLAT 5x6 package, featuring 0.56 V typical forward voltage at 125 °C and 30 A, 2 °C/W junction-to-case thermal resistance, and avalanche rating for robustness in DC/DC converters and telecom power supplies.
For engineers reviewing the STPS30H100DJF-TR datasheet, STPS30H100DJF-TR pinout, STPS30H100DJF-TR application, or STPS30H100DJF-TR equivalent, key selection criteria include low conduction loss (0.63 V max VF at 125 °C/30 A), thin 1 mm profile for space-constrained PCBs, and ECOPACK2 compliance for environmental requirements.
Technical Context
This Schottky rectifier uses a planar silicon structure optimized for high-frequency switching with negligible reverse recovery charge and extremely fast turn-off. Its low Rth(j-c) of 2 °C/W enables direct mounting to copper pads without external heatsinks in moderate-power SMPS designs.
The device operates up to 150 °C junction temperature and sustains 250 A non-repetitive surge current (10 ms sine), making it suitable for free-wheeling paths in synchronous buck converters where low forward drop minimizes conduction loss and improves efficiency at 12–48 V output rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; supports 48 V bus systems with 2× safety margin |
| IF(AV) | 30 A - Continuous DC forward current at Tc = 100 °C; defines steady-state power handling capability |
| VF (typ.) | 0.56 V @ 125 °C / 30 A - Low conduction loss directly reduces I²R heating in high-current paths |
| Rth(j-c) | 2 °C/W - Enables efficient heat transfer to PCB copper; allows >20 W dissipation with minimal ΔT |
| Tj(max) | 150 °C - High junction temperature rating permits operation in thermally dense telecom modules |
| IFSM | 250 A @ 10 ms - Withstands inrush and fault currents in DC/DC input stages without failure |
| Package | PowerFLAT 5x6 - 5 mm × 6 mm footprint with 1 mm height; compatible with automated SMT assembly |
Pinout & Package
PowerFLAT 5x6 is a surface-mount, dual-terminal package with exposed cathode pad on bottom for thermal conduction. The device has two terminals: anode (A) and cathode (K), with cathode connected to the large thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Input current entry point | Connected to source side (e.g., switch node or input rail); must be routed with low-inductance trace |
| Cathode (K) | Output current exit point + thermal path | Large exposed pad serves as both electrical terminal and primary heat sink to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.56 V typ. @ 125 °C/30 A - Reduces conduction loss by ~30% vs. comparable 100 V Si diodes |
| Extremely fast switching | No reverse recovery charge (Qrr ≈ 0) - Eliminates switching loss and EMI in >100 kHz DC/DC topologies |
| Avalanche rated | 265 W peak avalanche power @ 10 µs - Withstands inductive energy spikes during MOSFET turn-off |
| Thin 1 mm profile | Max height 1.00 mm - Enables use in ultra-low-profile telecom bricks and PoE-powered equipment |
| ECOPACK2 compliant | Lead-free, halogen-free, RoHS-compliant materials - Meets EU Directive 2011/65/EU and JEDEC J-STD-020 |
Applications
| Telecom AC-DC Front-End | Isolated DC/DC Converter Secondary |

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 | 100 V, 30 A, TO-220AC package; higher Rth(j-c) = 3.5 °C/W; VF = 0.72 V @ 125 °C/30 A | Requires heatsink for >15 A continuous; unsuitable for ultra-thin modules | Select when legacy through-hole assembly or higher surge tolerance (IFSM = 350 A) is prioritized over profile and thermal performance |
| ON Semiconductor MBR30H100CT | 100 V, 30 A, TO-220AB dual-diode; VF = 0.75 V @ 125 °C/30 A; no avalanche rating | Higher conduction loss and no avalanche capability limit use in unclamped inductive loads | Select only for cost-sensitive, non-avalanche-critical 50/60 Hz rectification where thermal budget allows larger footprint |
Compared with VS-30CPH01-M3 and MBR30H100CT, STPS30H100DJF-TR delivers superior thermal performance (2 °C/W vs. ≥3.5), lower conduction loss (0.56 V vs. ≥0.72 V), and guaranteed avalanche ruggedness-critical for high-frequency, space-constrained telecom and automotive power stages.
FAQ
What is the maximum allowable PCB copper area for optimal thermal performance?
The datasheet specifies Rth(j-a) derating versus copper surface area: with 8 cm² of 70 µm thick FR4 copper under the tab, Rth(j-a) drops to ~35 °C/W. For continuous 30 A operation, ≥12 cm² of 2-oz copper is recommended to maintain Tj < 135 °C at 60 °C ambient.
Does STPS30H100DJF-TR require a gate driver or control signal?
No. This is a passive Schottky rectifier with no control terminals. It conducts when anode voltage exceeds cathode voltage by >0.5 V and blocks when reverse biased. It operates autonomously without drivers, timing signals, or external bias.
Can STPS30H100DJF-TR replace a standard PN junction diode in an existing design?
Yes-if the original diode's VRRM ≥ 100 V and IF(AV) ≤ 30 A. However, verify layout: the PowerFLAT 5x6 footprint differs from TO-220 or D²PAK, and its low inductance benefits require short, wide traces to fully realize fast-switching advantages.
Is the cathode pad electrically isolated from the PCB ground plane?
No. The exposed cathode pad is the device's K terminal and must be connected to the circuit's cathode net-typically the output rail or ground return. It is not insulated; thermal interface material must be electrically conductive or the PCB copper must be part of the intended current path.
