Diodes Incorporated RS3BB-13-F

Overview

RS3BB-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode in SMB (DO-214AA) package, rated for 100 V peak repetitive reverse voltage (V_RRM), 3.0 A average forward current (I_O), and 150 ns maximum reverse recovery time (t_rr), used in AC/DC input stage rectification and DC-DC flyback snubber circuits.

For engineers reviewing the RS3BB-13-F datasheet, RS3BB-13-F pinout, RS3BB-13-F application, or RS3BB-13-F equivalent, key selection criteria include verified fast recovery performance (150 ns), low forward voltage drop (1.3 V @ 3.0 A), thermal resistance (25 K/W), SMB package compatibility with automated assembly, and UL 94V-0 flammability rating.

Technical Context

This device employs glass-passivated silicon die construction to ensure stable junction behavior under thermal cycling and high dv/dt conditions. Its fast recovery characteristic (t_rr = 150 ns) results from optimized carrier lifetime control, enabling reduced switching losses in high-frequency rectification up to 100 kHz.

The SMB package provides defined thermal path to PCB copper (R_JT = 25 K/W on 5.0 mm² pad), and the cathode band marking enables unambiguous polarity identification during placement. Rated surge current (I_FSM = 100 A, 8.3 ms half-sine) supports line transient immunity in offline power supplies.

FAQ

What is the maximum junction temperature for RS3BB-13-F?

The absolute maximum junction temperature is +150 °C, and the storage temperature range is −65 to +150 °C. Operation at T_j > 125 °C increases IR leakage exponentially; thermal design must maintain T_j ≤ 125 °C under worst-case load and ambient conditions using the specified R_JT and PCB copper area.

Does RS3BB-13-F have a cathode band or notch marking?

Yes - RS3BB-13-F uses a visible cathode band on the body of the SMB package to indicate the cathode terminal. This marking is standardized per DO-214AA and is used for automated optical inspection (AOI) and manual polarity verification during board assembly and rework.

Can RS3BB-13-F replace RS3AB-13-F in existing designs?

No - RS3AB-13-F has V_RRM = 50 V and t_rr = 150 ns, while RS3BB-13-F is rated for 100 V V_RRM. Substitution requires verifying that reverse voltage stress never exceeds 50 V in the original circuit; otherwise, overvoltage risk exists during transients or no-load conditions.

Is RS3BB-13-F lead-free and RoHS compliant?

Yes - RS3BB-13-F is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and China RoHS II. The "-13-F" suffix explicitly denotes lead-free, halogen-free, and RoHS-compliant construction per Diodes Incorporated's product coding system.
