Diodes Incorporated RS2DA-13-F

Overview

RS2DA-13-F from Diodes Incorporated is a 200 V, 1.5 A surface-mount fast recovery rectifier in SMA package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 1.5 A, and 50 A non-repetitive surge rating-designed for high-efficiency AC/DC front-end rectification in compact power supplies.

For engineers reviewing the RS2DA-13-F datasheet, RS2DA-13-F pinout, RS2DA-13-F application, or RS2DA-13-F equivalent, key selection criteria include peak repetitive reverse voltage (200 V), thermal resistance (20 °C/W), RoHS-compliant lead-free plating, and suitability for automated SMT assembly with J-STD-020 Level 1 moisture sensitivity.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for fast switching in line-frequency and moderate-frequency SMPS applications. Its glass-passivated die construction ensures stable reverse leakage (<5 µA at 25°C) and robust surge tolerance up to 50 A (8.3 ms half-sine).

The 150 ns reverse recovery time (measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A) enables reduced switching losses compared to standard recovery diodes, while its 20 °C/W junction-to-terminal thermal resistance supports reliable operation at 120°C terminal temperature under full 1.5 A DC load.

Key Specifications

Pinout & Package

RS2DA-13-F uses the SMA (DO-214AC) surface-mount package: molded plastic body (UL 94V-0), cathode band polarity marking, matte tin-plated terminals solderable per MIL-STD-202 Method 208, and 0.065 g mass.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Compared with STTH1L06S and MUR120, RS2DA-13-F offers the best balance of low VFM (1.3 V), industry-standard SMA footprint, and 50 A surge capability-making it optimal for cost-sensitive, thermally managed 50–100 kHz AC/DC converters.

FAQ

What is the maximum allowable junction temperature for RS2DA-13-F?

The absolute maximum junction temperature is +150°C, but continuous operation is rated for terminal temperature up to +120°C at full 1.5 A DC load. Derating begins above that point per Figure 1 in DS15004, with thermal resistance of 20 °C/W enabling direct PCB copper pad cooling without additional heatsinking.

Is RS2DA-13-F suitable for automotive applications?

RS2DA-13-F is not AEC-Q200 qualified out-of-the-box. While it operates from -65°C to +150°C and meets RoHS/Green requirements, Diodes specifies that automotive-grade variants require explicit AEC-Q200 qualification, PPAP capability, and IATF 16949 manufacturing-contact Diodes directly for such versions.

How does the SMA package compare to SMB for RS2DA-13-F?

RS2DA-13-F is exclusively offered in SMA (DO-214AC) package; RS2D-13-F is the SMB (DO-214AA) variant. SMA has smaller footprint (2.29 × 4.00 mm vs. 2.00 × 3.30 mm body), higher thermal resistance (20 vs. ~15 °C/W), and lower surge rating (50 A vs. 30 A for SMB), making SMA preferable where board space allows and surge robustness is prioritized.

What is the reverse leakage current at elevated temperature?

At 125°C and rated 200 V DC blocking voltage, reverse leakage current (IRM) is specified at ≤200 µA. This value reflects worst-case thermal drift and remains well below typical failure thresholds for bulk capacitance filtering in offline power supplies.
