Product details
Overview
SBRT30A100CTFP from Diodes Incorporated is a 30A dual common-cathode Trench Super Barrier Rectifier (SBR) in ITO-220AB package, rated for 100V peak repetitive reverse voltage, 15A average current per leg, 0.8V max forward voltage at 15A/25°C, and 0.15mA max reverse leakage at 100V/25°C - designed for high-efficiency, high-temperature DC/DC output rectification in industrial power supplies.
For engineers reviewing the SBRT30A100CTFP datasheet, SBRT30A100CTFP pinout, SBRT30A100CTFP application, or SBRT30A100CTFP equivalent, key selection criteria include thermal resistance (3.3°C/W junction-to-case), AEC-Q101 qualification, low VF stability up to 125°C, and ITO-220AB's insulated mounting capability for high-voltage isolation.
Technical Context
This dual-diode rectifier integrates two independent SBR dies in a single insulated TO-style package, enabling synchronous or interleaved output stage designs without external isolation. Its trench-based super barrier architecture delivers lower forward voltage than standard Schottky diodes while maintaining superior high-temperature leakage performance compared to conventional fast recovery rectifiers.
The device operates across –55°C to +150°C junction temperature range, with thermal derating defined down to zero current at 150°C case temperature. Reverse recovery is inherently soft and unmeasured - characteristic of majority-carrier SBR devices - eliminating switching ringing and EMI concerns typical of PN-junction fast recovery diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse voltage each anode can withstand without breakdown; defines safe operating margin in 48V–72V bus applications. |
| IO (per leg) | 15 A - Continuous average forward current per diode leg at TC = 100°C with heatsink; supports 30A total dual-leg output in compact PSU designs. |
| VF max | 0.80 V @ 15A, 25°C - Low conduction loss enables >95% efficiency in 12V-output converters; drops to 0.67V at 125°C for stable thermal behavior. |
| IR max | 0.15 mA @ 100V, 25°C - Ultra-low leakage ensures minimal standby power loss and prevents thermal runaway in sealed enclosures above 85°C. |
| RθJC | 3.3 °C/W - Junction-to-case thermal resistance with ITO-220AB package; enables direct heatsink mounting without insulating washer when isolation not required. |
| IFSM | 200 A @ 8.3ms - Non-repetitive surge rating allows robust handling of inrush and transient overloads in motor drive or battery-charger front ends. |
Pinout & Package
SBRT30A100CTFP uses the insulated TO-220 variant (ITO-220AB), featuring electrically isolated metal tab for direct heatsink mounting without thermal pad or insulator - critical for high-voltage secondary-side rectification where creepage/clearance must be maintained. Pin configuration is dual-anode, common-cathode: pins 1 and 2 are anodes (A1, A2), pin 3 is cathode (K).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first diode leg | Connects to transformer secondary winding or phase node; carries full 15A leg current during conduction. |
| Pin 2 (Anode 2) | Anode of second diode leg | Enables dual-phase or parallel rectification; electrically isolated from Pin 1 but shares cathode return path. |
| Pin 3 (Cathode) | Common cathode terminal | Single low-inductance output node for both legs; connects directly to output capacitor bank and load return. |
| Metal Tab | Electrically isolated case | Provides mechanical mounting and thermal path; rated for ≥2500 VAC isolation from internal die - verified per ITO-220AB spec. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at high temperature | 0.67 V @ 15A, 125°C - maintains efficiency and reduces thermal stress in enclosed, fanless power supplies. |
| AEC-Q101 qualified | Qualified for automotive-grade reliability - including temperature cycling, HTRB, and UHAST - enabling use in under-hood DC/DC converters. |
| Insulated ITO-220AB package | 2500 VAC isolation between tab and die - eliminates need for mica washers or silicone pads in high-voltage secondary-side layouts. |
| Halogen- and antimony-free "Green" construction | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - meets strict environmental compliance for EU, China RoHS, and automotive ELV directives. |
Applications
| Server VRM Output Rectification | Industrial 48V DC/DC Converter |
|---|---|
Use Scenario: High-current, low-voltage output stage of 48V-to-12V/5V server VRMs with tight thermal constraints.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-temperature rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H100CG | 100V, 30A dual common-cathode Schottky; VF = 0.82V @ 15A/25°C; IR = 1.5mA @ 100V/25°C; TO-220AC package (non-insulated tab). | Lacks AEC-Q101 qualification and exhibits 10× higher leakage at 125°C - unsuitable for sealed automotive or industrial enclosures. | Select only if isolation is unnecessary and thermal design accommodates higher leakage-induced self-heating. |
| VB30100C-E3/4W | 100V, 30A dual common-cathode SBR; VF = 0.75V @ 15A/25°C; IR = 0.2mA @ 100V/25°C; TO-220AB (non-insulated tab); no AEC-Q101 data published. | Non-insulated tab requires thermal pad and electrical isolation hardware; lacks automotive qualification documentation. | Preferable for cost-sensitive industrial supplies where heatsink isolation is managed externally and AEC-Q101 is not mandated. |
Compared with STPS30H100CG and VB30100C-E3/4W, SBRT30A100CTFP uniquely combines ITO-220AB insulation, AEC-Q101 qualification, and sub-0.2mA leakage at 125°C - making it the only option for space-constrained, high-reliability, high-temperature rectification where electrical isolation and automotive compliance are mandatory.

FAQ
What is the maximum allowable case temperature for continuous operation?
The SBRT30A100CTFP supports continuous operation up to 150°C case temperature, with DC forward current linearly derated from 15A at 100°C to 0A at 150°C per Figure 4 in DS37998. Operation beyond this requires transient-only duty cycle validation.
Can the metal tab be used as a functional electrical node?
No - the ITO-220AB metal tab is electrically isolated from all internal die terminals (pins 1–3) and rated for ≥2500 VAC isolation. It serves solely as a thermal interface and mechanical mount; connecting it to any circuit node violates isolation integrity and voids safety certification.
Is SBRT30A100CTFP suitable for synchronous rectification topologies?
No - this is a passive rectifier with fixed conduction timing governed by forward bias. It cannot replace actively controlled MOSFETs in synchronous rectification; however, it serves as a robust, low-loss alternative in simpler diode-rectified or quasi-resonant topologies where control complexity must be minimized.
How does its reverse recovery behavior compare to fast recovery diodes?
As a majority-carrier Trench SBR, SBRT30A100CTFP has no minority-carrier storage delay and exhibits soft, near-zero reverse recovery charge (Qrr). Unlike fast recovery diodes, it generates negligible switching noise or voltage overshoot - confirmed by absence of Qrr specification and soft reverse IV curves in Figures 1–2 of DS37998.
