Product details
Overview
SRF1630 from Taiwan Semiconductor is a 16A, 30V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AB package, featuring 200A surge current capability, 2.5°C/W junction-to-case thermal resistance, and low 0.55V forward voltage at 8A/25°C. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the SRF1630 datasheet, SRF1630 pinout, SRF1630 application, or SRF1630 equivalent, key selection criteria include repetitive peak reverse voltage (30V), junction temperature range (–55°C to +125°C), reverse leakage (≤500 µA at 25°C), thermal performance, and AEC-Q101 qualification status.
Technical Context
The SRF1630 integrates dual Schottky dies in a single ITO-220AB package with guard ring structure for overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its thermal design supports 16A continuous forward current with derating above 25°C ambient.
Electrical behavior is defined by low VF (max 0.55V @ 8A, 25°C), tight IR control (≤500 µA @ VR=30V, 25°C; ≤15 mA @ 100°C), and robust surge handling (200A, 8.3ms half-sine). Junction temperature limit is rated at +125°C for standard version.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating margin in 24V automotive or 28V industrial bus applications. |
| IF | 16 A - Continuous forward current rating at case temperature ≤75°C; determines heatsink sizing in high-density power supplies. |
| IFSM | 200 A - Non-repetitive surge current capacity; enables reliable operation during cold-start or load-dump transients. |
| VF @ 8A, 25°C | ≤0.55 V - Low conduction loss per diode; reduces power dissipation and improves system efficiency vs. silicon rectifiers. |
| RθJC | 2.5 °C/W - Thermal resistance from junction to case; allows direct mounting to heatsink without thermal interface material in many designs. |
| IR @ 30V, 25°C | ≤500 µA - Reverse leakage current; ensures minimal standby loss in always-on power rails. |
| TJ Operating Range | –55°C to +125°C - Extended temperature capability supporting under-hood automotive and industrial environments. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with internal isolation between collector (case) and emitter terminals; UL Recognized (E-326243), RoHS and halogen-free compliant; 1.70g weight; mounting torque ≤0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first Schottky die | Connected to high-side switching node in dual-output or interleaved converter topologies. |
| Cathode (Case) | Common cathode / thermal path | Electrically isolated metal tab serves as heat sink interface and return path; requires insulating washer if mounted to grounded chassis. |
| Anode 2 | Input terminal for second Schottky die | Enables dual independent rectification paths or parallel configuration for higher current without external paralleling components. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics; includes stress testing per JESD22 and whisker resistance (JESD201 Class 2). |
| Guard ring structure | Enhances edge termination reliability; prevents premature avalanche breakdown under transient overvoltage conditions. |
| Dual-die configuration | Two independent Schottky junctions in one package; eliminates interconnect losses and layout asymmetry in dual-rail outputs. |
| UL Recognized (E-326243) | Meets safety requirements for end-equipment certification; simplifies compliance for industrial and medical auxiliary power supplies. |
| Matte tin-plated leads | Ensures consistent solder wetting and joint integrity per J-STD-002; compatible with lead-free reflow profiles. |
Applications
| Automotive DC-DC Converter | Industrial SMPS Output Stage |
|---|---|
Use Scenario: 12V-to-5V/3.3V buck converter in engine control unit (ECU) with wide input transients. IC Role / Device Role / Timing Role: Primary output rectifier replacing fast recovery diodes to reduce conduction loss and improve light-load efficiency. Use Value: 0.55V VF at 8A lowers average power loss by >40% vs. comparable Si diode, directly extending ECU thermal margin. | Use Scenario: 48V-input telecom rectifier module delivering 12V/20A to base station subsystems. IC Role / Device Role / Timing Role: Synchronous rectifier alternative where gate drive complexity is undesirable; used in secondary-side freewheeling path. Use Value: Dual-die layout enables balanced current sharing across two 10A rails without external current-sharing resistors or magnetics. |
| Laptop Adapter Secondary Side | Server PSU Hold-Up Capacitor Charging Path |
Use Scenario: High-density 19V/3.42A adapter with <15mm height constraint and >90% efficiency target. IC Role / Device Role / Timing Role: Low-VF Schottky rectifier on LLC resonant converter secondary; operates in discontinuous conduction mode. Use Value: 2.5°C/W RθJC allows direct heatsink attachment without thermal pad, saving 0.3mm Z-height in ultra-thin adapter designs. | Use Scenario: 380V DC-link to 12V auxiliary supply charging hold-up capacitors during AC dropout events. IC Role / Device Role / Timing Role: Surge-rated rectifier conducting brief high-current pulses (200A, 8.3ms) during brownout recovery. Use Value: Rated IFSM of 200A exceeds IEC 61000-4-11 surge requirement for Class A equipment, eliminating need for external crowbar protection. |
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-16CTH03-M3 | Same ITO-220AB package, 16A/30V, VF = 0.52V (typ), but not AEC-Q101 qualified; RθJC = 2.6°C/W. | Targeted at commercial/industrial SMPS only; lacks automotive stress validation and whisker resistance data. | Select when AEC-Q101 is not required and lowest possible VF is prioritized over qualification documentation. |
| ON Semiconductor MBR1630CT | TO-220AB package (non-isolated case), 16A/30V, VF = 0.57V (max), TJ = –65°C to +175°C, no AEC-Q101 listing. | Higher max junction temperature enables operation in hotter environments, but case is electrically connected to cathode - requires isolation hardware. | Choose when thermal ceiling >125°C is critical and board-level isolation can be implemented reliably. |
Compared with VS-16CTH03-M3 and MBR1630CT, the SRF1630 uniquely combines AEC-Q101 qualification, electrically isolated case (ITO-220AB), and 2.5°C/W thermal resistance - making it the only option qualified for under-hood automotive use without added isolation or derating.

FAQ
What is the maximum junction temperature rating for SRF1630?
The SRF1630 has a maximum junction temperature (TJ) rating of +125°C for standard versions. This rating applies across its full operating current range when case temperature is maintained within limits defined by the 2.5°C/W thermal resistance and ambient conditions. The device must not exceed this TJ limit during steady-state or transient operation to ensure reliability and AEC-Q101 compliance.
Is SRF1630 pin-compatible with other parts in the SRF16xx family?
Yes, all SRF16xx devices including SRF1630 share identical ITO-220AB package dimensions, pinout, and mechanical footprint. Anode 1, Cathode (case), and Anode 2 positions are fixed across the family, enabling drop-in replacement between voltage variants (e.g., SRF1620 to SRF16150) without PCB redesign - provided voltage and thermal requirements are verified for the new rating.
Does SRF1630 have an AEC-Q101 qualification certificate?
Yes, the SRF1630H variant is explicitly AEC-Q101 qualified, as confirmed in Taiwan Semiconductor's ordering information and product documentation. The "H" suffix denotes qualification; standard SRF1630 (without H) meets all electrical specs but lacks formal AEC-Q101 test reporting. For automotive applications, specify SRF1630H to ensure certified qualification.
What is the reverse leakage current of SRF1630 at 100°C?
The SRF1630 exhibits a maximum reverse leakage current (IR) of 15 mA at rated VRRM = 30V and junction temperature of 100°C, per the manufacturer's electrical specifications table. This value is measured under 30ms pulse conditions and reflects typical worst-case behavior in high-temperature automotive environments.
Can SRF1630 be used in surface-mount designs?
No, the SRF1630 is packaged exclusively in through-hole ITO-220AB and is not offered in surface-mount variants. Its thermal design relies on mechanical mounting of the isolated metal tab to an external heatsink, which requires screw or clamp fixation - incompatible with reflow soldering or standard SMT assembly processes.
