Product details
Overview
STPS30SM100SG-TR from STMicroelectronics is a 100 V, 30 A average forward current Schottky rectifier in D²PAK (TO-263) package, optimized for high-frequency switch-mode power supplies. It delivers low forward voltage drop (0.63 V typ. at 25 °C, 30 A), avalanche-rated ruggedness (1545 W peak), and 150 °C max junction temperature-enabling high-efficiency operation in notebook adapters and DC/DC converters.
For engineers reviewing the STPS30SM100SG-TR datasheet, STPS30SM100SG-TR pinout, STPS30SM100SG-TR application, or STPS30SM100SG-TR equivalent, key selection criteria include forward voltage vs. load, thermal resistance (Rth(j-c) = 1 °C/W), avalanche capability, TO-263 footprint compatibility, and ECOPACK®2 compliance for industrial-grade power conversion designs.
Technical Context
This single-diode Schottky rectifier operates without minority-carrier storage, enabling zero reverse recovery time and minimal switching losses in high-frequency SMPS topologies. Its low VF and high IF(AV) support continuous conduction mode (CCM) operation up to 30 A with case temperature limited to 125 °C.
The device is rated for repetitive peak reverse voltage (VRRM) of 100 V and surge non-repetitive forward current (IFSM) of 400 A (10 ms sine), with thermal resistance from junction-to-case fixed at 1 °C/W-requiring direct heatsink mounting for sustained 30 A loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input stages up to 100 V DC or rectified AC rails without breakdown |
| IF(AV) | 30 A - continuous forward current rating at Tc = 125 °C, defining maximum steady-state output capability |
| VF (typ.) | 0.63 V @ 30 A, 25 °C - enables <19 W conduction loss (P ≈ 0.58×IF(AV) + 0.0033×IF(RMS)²) |
| Rth(j-c) | 1 °C/W - mandates direct metal heatsink contact for thermal management under full load |
| Tj(max) | 150 °C - allows operation in thermally constrained environments like enclosed adapters |
| IFSM | 400 A @ 10 ms - withstands inrush and transient overloads common in AC-DC front ends |
| ECOPACK®2 | Compliant - meets RoHS and halogen-free requirements for industrial and consumer power supplies |
Pinout & Package
Package: D²PAK (TO-263), surface-mount, 3-terminal outline with exposed drain pad (pin 2) for thermal and electrical connection. Dimensions per DS6167 Rev 7: 9.35 mm × 10.55 mm × 15.85 mm (L × W × H), 1.48 g weight, tape-and-reel packaging (1000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Input-side terminal; connects to high-side switching node or transformer secondary |
| 2 (Cathode / Tab) | Cathode and thermal pad | Output-side return path and primary thermal interface-must be soldered to large copper pour or heatsink |
| 3 (Anode) | Second anode (internally tied to Pin 1) | Redundant anode terminal for enhanced current sharing and mechanical stability in high-current layouts |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated operation | 1545 W peak avalanche power (10 µs pulse, Tj = 125 °C) enables robustness against inductive switching transients |
| Low forward voltage | 0.63 V typ. @ 30 A, 25 °C reduces conduction loss by ~25% vs. comparable 100 V Si diodes |
| High-frequency suitability | Zero reverse recovery charge (Qrr = 0) eliminates switching loss and EMI from recovery spikes |
| D²PAK thermal performance | 1 °C/W junction-to-case resistance supports >25 W dissipation with standard PCB copper area |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy meets global environmental regulations for end-product certification |
Applications
| Desktop Power Supply | LED Lighting Driver |
|---|---|
Use Scenario: Secondary-side rectification in 300–500 W ATX PSUs operating at 100–500 kHz switching frequency. IC Role / Device Role / Timing Role: Output rectifier replacing fast recovery diodes to reduce heat and improve efficiency at light-to-full load. Use Value: 0.63 V VF cuts conduction loss by ~3.5 W vs. Si FRD at 30 A, lowering heatsink size and audible noise. | Use Scenario: Constant-current output rectification in isolated flyback LED drivers for commercial lighting (20–100 W). IC Role / Device Role / Timing Role: High-efficiency synchronous rectification alternative where gate drive complexity is avoided. Use Value: Zero Qrr prevents voltage overshoot on MOSFET switches, improving reliability in compact, unventilated fixtures. |

Use Scenario: 65–90 W AC-DC adapter output stage with tight thermal envelope and 12 V/5 V dual-rail outputs. IC Role / Device Role / Timing Role: Primary output rectifier in LLC or QR flyback topology, directly mounted to aluminum housing. Use Value: Rth(j-c) = 1 °C/W enables 30 A operation with ≤35 °C rise above heatsink-critical for fanless designs. | Use Scenario: High-current 12 V rail rectification in game console internal power modules handling burst loads up to 40 A. IC Role / Device Role / Timing Role: Avalanche-tolerant rectifier absorbing energy from inductive load dumps during rapid power cycling. Use Value: 400 A IFSM and 1545 W PARM prevent failure during GPU power state transitions and system wake events. |
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 VRRM (100 V), lower IF(AV) (25 A), higher VF (0.72 V typ.), TO-220AC package | Requires larger heatsink at 30 A; not surface-mount compatible | Select when through-hole assembly or legacy TO-220 footprint is mandatory |
| ON Semiconductor MBR30100CTG | 100 V dual common-cathode die, 30 A per diode, TO-220AB, VF = 0.75 V typ. | Higher conduction loss; dual configuration adds layout flexibility but no avalanche rating | Choose for cost-sensitive dual-output designs where avalanche immunity is not required |
Compared with VS-30CPH01-M3/45 and MBR30100CTG, STPS30SM100SG-TR uniquely combines D²PAK SMT compatibility, 30 A rating, 0.63 V VF, and certified avalanche ruggedness-making it optimal for space-constrained, high-reliability 100 V SMPS outputs.

FAQ
What is the maximum allowable case temperature for continuous 30 A operation?
The datasheet specifies IF(AV) = 30 A at Tc = 125 °C. Operation at this current requires maintaining case temperature ≤125 °C via adequate PCB copper area or external heatsink. Exceeding this temperature derates average current per Figure 2 in DS6167.
Is STPS30SM100SG-TR pin-compatible with other D²PAK Schottky rectifiers?
Yes-it follows standard 3-pin D²PAK (TO-263) mechanical dimensions and terminal assignment (Anode–Cathode–Anode). However, electrical parameters (VF, IFSM, avalanche rating) differ across manufacturers; verify thermal and surge margins before substitution.
Does this part require a gate driver or control signal?
No. STPS30SM100SG-TR is a passive two-terminal Schottky diode. It conducts when anode voltage exceeds cathode voltage by >0.4 V and blocks reverse voltage up to 100 V-no external bias, timing, or logic control is needed.
How does its avalanche rating compare to standard Schottky diodes?
Unlike most Schottky diodes, STPS30SM100SG-TR is fully specified for repetitive avalanche operation (1545 W, 10 µs pulses). This allows safe clamping of inductive switching transients without degradation-where standard Schottkys would fail catastrophically under similar stress.
