Diodes Incorporated RS2D-13-F

Overview

RS2D-13-F from Diodes Incorporated is a 1.5A surface-mount fast recovery rectifier diode with 200V peak repetitive reverse voltage (VRRM), 1.3V forward voltage at 1.5A, and 500ns reverse recovery time (trr), designed for high-efficiency AC/DC conversion in compact power supplies and LED drivers.

For engineers reviewing the RS2D-13-F datasheet, RS2D-13-F pinout, RS2D-13-F application, or RS2D-13-F equivalent, key selection criteria include its SMA package thermal resistance (20°C/W), 50A non-repetitive surge rating, RoHS-compliant matte tin plating, and suitability for automated SMT assembly in industrial and consumer power stages.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for fast switching in offline SMPS, flyback converters, and input bridge legs. Its glass-passivated die construction ensures stable reverse leakage (<5µA at 25°C) and robustness against moisture and mechanical stress.

The 500ns reverse recovery time enables efficient operation at switching frequencies up to ~100kHz without excessive switching loss, while its 20°C/W junction-to-terminal thermal resistance supports reliable 1.5A continuous conduction when mounted on standard 5mm² copper pads.

Key Specifications

Pinout & Package

RS2D-13-F is housed in the SMA (DO-214AC) surface-mount plastic package, featuring a cathode band marking on the body and two terminals: anode and cathode. The package complies with UL 94V-0 flammability rating and J-STD-020 moisture sensitivity level 1.

Equivalent & Alternatives

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

Compared with STTH1L06F and MUR120, RS2D-13-F delivers balanced trade-offs: faster than STTH1L06F for mid-frequency SMPS yet more manufacturable than MUR120, making it optimal for cost-sensitive, high-volume SMT power supplies requiring 200V blocking and 1.5A average current.

FAQ

What is the maximum operating temperature for RS2D-13-F?

The RS2D-13-F has an operating junction temperature range of –65°C to +150°C and a storage temperature range matching that. Its 1.5A average current rating is specified at 120°C terminal temperature, and derating begins above that point per Figure 1 in DS15004 Rev. 12–2.

Is RS2D-13-F qualified for automotive applications?

RS2D-13-F itself is not AEC-Q101 qualified; however, Diodes offers automotive-grade variants (e.g., RS2DQ-13-F) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. Standard RS2D-13-F is intended for industrial and commercial use.

How does the SMA package affect thermal performance?

The SMA package provides a junction-to-terminal thermal resistance of 20°C/W when mounted on 5.0 mm² copper pads. This allows effective passive cooling without heatsinks in most 1.5A applications, though board layout-especially copper area and via count-directly impacts actual operating temperature.

Can RS2D-13-F replace RS2B-13-F in an existing design?

Yes, RS2D-13-F (200V VRRM) can directly replace RS2B-13-F (100V VRRM) if the circuit's peak reverse voltage remains ≤200V. No layout or bias changes are needed-the SMA footprint, pinout, and thermal behavior are identical; only the blocking voltage rating increases.
