Diodes Incorporated RS1D-13-F

Overview

RS1D-13-F from Diodes Incorporated is a 1.0A surface-mount fast recovery rectifier in SMA package, rated for 200V peak repetitive reverse voltage (V_RRM), with 1.3V max forward voltage at 1.0A and 150ns reverse recovery time (t_RR). It delivers high-efficiency AC/DC conversion in compact power supplies for consumer adapters and industrial SMPS.

For engineers reviewing the RS1D-13-F datasheet, RS1D-13-F pinout, RS1D-13-F application, or RS1D-13-F equivalent, key selection criteria include its 200V blocking capability, 30A surge rating, RoHS-compliant lead-free finish, and thermal resistance of 20°C/W - critical for thermally constrained board layouts.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for fast switching in single-phase, half-wave configurations with resistive or inductive loads. Its glass-passivated die construction ensures stable reverse leakage (<5.0µA at 25°C) and robust surge tolerance up to 30A (8.3ms half-sine).

The SMA package enables automated assembly and supports terminal temperature operation up to +120°C, with derating required above that point per the forward current curve. Reverse recovery is characterized under standardized conditions (I_F = 0.5A, I_R = 1.0A, I_RR = 0.25A), confirming suitability for 50–100kHz switching topologies.

FAQ

What is the maximum junction temperature for RS1D-13-F?

The RS1D-13-F has an operating junction temperature range of –65°C to +150°C. Its average rectified current rating of 1.0A is specified at terminal temperature (T_T) = +120°C, and derating is required above that point per Figure 1 in the datasheet. Thermal design must ensure R_θJT = 20°C/W is respected to avoid exceeding T_J(max).

Is RS1D-13-F suitable for capacitive-load applications?

No - the datasheet explicitly states that for capacitive loads, the average rectified output current must be derated by 20%. This is due to increased peak currents and stress during capacitor charging. Use only with resistive or inductive loads unless additional current derating and thermal validation are performed.

Does RS1D-13-F have a defined reverse recovery charge (Q_rr) value?

The datasheet does not specify Q_rr directly, but t_RR = 150ns is provided under defined test conditions (I_F = 0.5A, I_R = 1.0A, I_RR = 0.25A). Q_rr can be estimated from t_RR and di/dt in circuit simulation, but no guaranteed min/max Q_rr is published by Diodes Incorporated for this part.

Can RS1D-13-F replace RS1D-E3/54 in existing designs?

Yes - RS1D-13-F and RS1D-E3/54 share identical electrical specifications (200V V_RRM, 1.0A I_O, 150ns t_RR, 1.3V V_FM) and SMA package dimensions. The "-13-F" suffix denotes tape-and-reel packaging (5000 pcs) and RoHS-3 compliance; "E3/54" indicates different packaging and older RoHS-2 compliance. No layout or performance change is needed.
