Product details
Overview
SRAS2030HMNG from Taiwan Semiconductor is a 20A, 30V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC conversion with low forward voltage (0.57 V at 20 A, 25°C), high surge capability (330 A), and junction temperature rating up to +150°C. It serves as the primary output rectifier in compact, high-frequency SMPS designs.
For engineers reviewing the SRAS2030HMNG datasheet, SRAS2030HMNG pinout, SRAS2030HMNG application, or SRAS2030HMNG equivalent, key selection criteria include its 30 V repetitive peak reverse voltage, 1.5 °C/W junction-to-case thermal resistance, moisture sensitivity level 1 compliance, and suitability for automated SMT assembly in power adapters and onboard converters.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring structure to enhance overvoltage ruggedness and suppress leakage under transient stress. Its low VF and fast recovery enable minimal conduction loss in continuous conduction mode (CCM) topologies operating above 100 kHz.
The TO-263AB package provides robust thermal performance (RθJC = 1.5 °C/W) and supports high-current PCB land patterns per manufacturer-recommended pad layout. Matte tin-plated terminals meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.
Key Specifications

|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating range in buck or flyback secondary-side rectification |
| IF | 20 A - Continuous average forward current at case temperature ≤ 110°C; enables use in 40–60 W DC/DC modules |
| IFSM | 330 A - Non-repetitive surge current (8.3 ms half-sine); withstands startup inrush and short-circuit transients |
| VF | 0.57 V @ 20 A, 25°C - Low conduction loss reduces heat generation and improves system efficiency >92% in 12 V output rails |
| RθJC | 1.5 °C/W - Enables direct heatsinking to PCB copper; allows 15–20 W dissipation with 30°C temperature rise over ambient |
| TJ max | +150°C - Supports operation in sealed enclosures or high-ambient industrial environments without derating below 100% load |
| MSL | Level 1 (per J-STD-020) - No floor life limitation; compatible with standard reflow profiles without baking preconditioning |
Pinout & Package

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-20BQ030-M3/45 | Same VRRM (30 V), slightly higher VF (0.62 V @ 20 A), RθJC = 1.8 °C/W | Lower thermal performance limits max power in space-constrained layouts | Prefer SRAS2030HMNG where board area is limited and thermal budget is tight |
| ON Semiconductor SB2030 | Identical VRRM/IF ratings but lower IFSM (250 A), no guard ring, MSL Level 2a | Requires baking before reflow; less robust under surge conditions | Prefer SRAS2030HMNG for high-reliability industrial or telecom deployments |
Compared with VS-20BQ030-M3/45 and SB2030, SRAS2030HMNG delivers superior thermal resistance (1.5 vs. 1.8/2.2 °C/W), higher surge margin (330 vs. 250–280 A), and integrated guard ring protection-making it optimal for compact, high-power-density, and mission-critical rectification.

FAQ
What is the maximum junction temperature rating for SRAS2030HMNG?
The SRAS2030HMNG has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official TSC datasheet (Version M2103). This allows uninterrupted 20 A operation at case temperatures up to 110°C when mounted on adequate copper area. Thermal design must maintain TJ ≤ 150°C under worst-case ambient and load conditions to ensure reliability.
Does SRAS2030HMNG have a guard ring structure?
Yes, SRAS2030HMNG incorporates an integrated guard ring structure explicitly stated in the "Features" section of the TSC datasheet. This design enhances overvoltage protection by controlling electric field distribution at the die edge, improving ruggedness against transient reverse voltage spikes and dv/dt stress without requiring external clamping components.
What is the forward voltage of SRAS2030HMNG at rated current and temperature?
The forward voltage (VF) of SRAS2030HMNG is 0.57 V typical at IF = 20 A and TJ = 25°C, as specified in the "Electrical Specifications" table. At elevated junction temperatures (e.g., 100°C), VF decreases slightly due to Schottky diode physics, remaining ≤0.54 V under the same current condition.
Is SRAS2030HMNG compliant with RoHS and halogen-free standards?
Yes, SRAS2030HMNG is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the TSC datasheet. The molding compound contains no brominated flame retardants, and all homogeneous materials meet EU Directive 2011/65/EU Annex II substance restrictions.
What is the moisture sensitivity level (MSL) of SRAS2030HMNG?
SRAS2030HMNG is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry pack or baking prior to reflow soldering. This simplifies SMT handling and eliminates process steps in high-volume manufacturing environments.
