Diodes Incorporated RS2M-13-F

Overview

RS2M-13-F from Diodes Incorporated is a 1.5A surface-mount fast recovery rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.3V forward voltage at 1.5A (VFM), and 150ns reverse recovery time (trr), designed for high-efficiency AC/DC front-end rectification in offline power supplies and industrial SMPS.

For engineers reviewing the RS2M-13-F datasheet, RS2M-13-F pinout, RS2M-13-F application, or RS2M-13-F equivalent, key selection criteria include its 1000V blocking capability, 50A non-repetitive surge rating, RoHS-compliant lead-free matte tin plating, and SMA package thermal resistance of 20°C/W under standard PCB mounting conditions.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for fast switching in line-frequency and quasi-resonant converters. Its glass-passivated die construction ensures stable performance under thermal cycling and humidity stress, while the cathode band polarity marking enables reliable automated optical inspection during SMT placement.

The 150ns reverse recovery time (trr) is measured under standardized conditions (IF = 0.5A, IR = 1.0A, Irr = 0.25A), enabling reduced switching losses compared to general-purpose rectifiers. Its 30pF typical junction capacitance at 4V reverse bias supports predictable EMI behavior in high-frequency filter stages.

Key Specifications

Pinout & Package

RS2M-13-F is housed in the SMA (DO-214AC) surface-mount package: molded plastic body with UL 94V-0 flammability rating, moisture sensitivity level 1 per J-STD-020, and matte tin-plated terminals solderable per MIL-STD-202, Method 208. Polarity is indicated by a cathode band on the body end.

FAQ

What is the maximum allowable junction temperature for RS2M-13-F?

The absolute maximum junction temperature is +150°C, as specified in the Thermal Characteristics table. Operation above this limit risks permanent degradation of the PN junction. Derating curves in Figure 1 show that average rectified current must be reduced to 1.0A at 120°C terminal temperature, assuming standard PCB copper pad heatsinking.

Is RS2M-13-F qualified for automotive applications?

RS2M-13-F is not AEC-Q101 qualified out-of-the-box. The datasheet notes that automotive-grade versions require specific change control, PPAP capability, and manufacturing in IATF 16949-certified facilities-available upon request via Diodes' automotive sales team, but not applicable to the standard RS2M-13-F orderable part.

Can RS2M-13-F replace a 1N4007 in a 120VAC circuit?

Yes-RS2M-13-F exceeds 1N4007 specifications in every key parameter: 1000V vs. 1000V VRRM (equal), 1.5A vs. 1.0A IO (higher), 150ns vs. ~2μs trr (much faster), and 50A vs. 30A IFSM (higher). Its faster recovery also reduces EMI in switched-mode circuits where 1N4007 is marginal.

What is the recommended PCB pad layout for RS2M-13-F?

The datasheet specifies an SMA footprint with C = 4.00 mm, G = 1.50 mm, X = 2.50 mm, X1 = 6.50 mm, and Y = 1.70 mm (all dimensions in mm). Use 5.0 mm² copper pads per terminal to achieve the stated 20°C/W RθJT; avoid thermal relief spokes on high-current traces to maintain thermal performance.
