Product details

Overview

SRS1630 from Taiwan Semiconductor is a 16A, 30V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, featuring dual-die configuration, 150A surge capability, 0.55V forward voltage at 8A/25°C, and junction temperature rating up to +150°C. It serves as a high-efficiency output rectifier in compact DC-DC converters.

For engineers reviewing the SRS1630 datasheet, SRS1630 pinout, SRS1630 application, or SRS1630 equivalent, key selection criteria include its 30V V_RRM, low VF performance at elevated temperature, moisture sensitivity level 1 compliance, RoHS/halogen-free status, and thermal resistance of 2°C/W junction-to-case.

Technical Context

This Schottky rectifier uses dual-die parallel configuration in a single TO-263AB package to achieve 16A average forward current with enhanced thermal dissipation. Its guard ring structure provides overvoltage protection, and matte tin-plated terminals ensure reliable solderability per J-STD-002.

The device operates across -55°C to +150°C junction temperature range, exhibits 500µA max reverse leakage at 25°C and rated VR, and maintains stable forward conduction with pulse-tested VF characterization under 0.3ms conditions.

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 30V V_RRM, 16A I_F, TO-263AB; VF = 0.57V @ 8A - 3.6% higher conduction loss	Higher IR (1mA @ 25°C) - less suitable for high-temp standby modes	Preferred where Vishay qualification or long-term supply continuity is mandated
ON Semiconductor SB1630	30V V_RRM, 16A I_F, TO-220AC package; no dual-die configuration; R_θJC = 3.5°C/W	Requires larger PCB area and external heatsink for equivalent thermal performance	Selected when legacy TO-220 layout reuse is prioritized over space savings

Compared with VS-16CTH03-M3 and SB1630, the SRS1630 delivers lower forward voltage, dual-die redundancy, and superior thermal resistance in the same D2PAK footprint - making it optimal for space-constrained, high-efficiency, and thermally demanding applications.

FAQ

What is the maximum junction temperature rating for the SRS1630?

The SRS1630 has a maximum junction temperature rating of +150°C, allowing continuous operation in high-ambient industrial or enclosed power supply environments without thermal derating below full 16A current. This rating is confirmed in the Absolute Maximum Ratings table and supported by its 2°C/W junction-to-case thermal resistance.

Does the SRS1630 have a dual-die configuration, and how does it affect circuit design?

Yes, the SRS1630 integrates two independent Schottky dies in a single TO-263AB package with a shared cathode terminal. This enables either parallel current sharing for enhanced reliability or separate anode routing for center-tapped transformer configurations - reducing component count versus discrete dual-diode solutions.

What is the forward voltage specification of the SRS1630 under typical operating conditions?

The SRS1630 specifies a typical forward voltage of 0.55V at 8A and 25°C, measured with 0.3ms pulse width. At 16A and 100°C junction temperature, VF remains ≤0.72V - critical for maintaining high efficiency in thermally stressed DC-DC converter outputs.

Is the SRS1630 compliant with RoHS and halogen-free standards?

Yes, the SRS1630 is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These certifications are explicitly stated in the Features section and verified through material declarations provided by Taiwan Semiconductor.

What is the moisture sensitivity level (MSL) of the SRS1630, and what does it mean for assembly?

The SRS1630 has Moisture Sensitivity Level 1 per J-STD-020, meaning it has unlimited floor life and requires no dry-packing or baking prior to reflow soldering. This simplifies SMT line logistics and eliminates moisture-related popcorning risks during standard lead-free reflow profiles.
