Diodes Incorporated RS1KB-13-F

Overview

RS1KB-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode rated for 800 V peak repetitive reverse voltage, 1.0 A average forward current, and 30 A non-repetitive surge current, with 150 ns reverse recovery time and 1.3 V forward voltage drop at 1.0 A - used in AC/DC front-end rectification and flyback snubber circuits.

For engineers reviewing the RS1KB-13-F datasheet, RS1KB-13-F pinout, RS1KB-13-F application, or RS1KB-13-F equivalent, key selection criteria include reverse voltage margin, thermal resistance (20 °C/W), RoHS-compliant lead-free finish, SMB package footprint compatibility, and fast recovery performance in high-frequency switching supplies.

Technical Context

This device operates as a unidirectional silicon junction rectifier optimized for high-efficiency switching power conversion. Its glass-passivated die construction ensures stable reverse leakage (<200 µA at +125°C) and robust surge tolerance (30 A, 8.3 ms half-sine).

The SMB package enables automated assembly with UL 94V-0 flammability rating and moisture sensitivity level 1. Polarity is indicated by a cathode band; terminals use matte tin annealed over copper alloy for MIL-STD-202-compliant solderability.

FAQ

What is the maximum junction temperature for RS1KB-13-F?

The RS1KB-13-F has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (R_θJT = 20 °C/W) allows safe operation at 1.0 A average current when terminal temperature is maintained ≤ +120°C, per the derating curve in DS15002 Rev. 15–2.

Is RS1KB-13-F pin-compatible with other SMB-packaged rectifiers?

Yes - RS1KB-13-F uses the standard SMB (DO-214AA) outline with anode/cathode terminals in fixed positions per JEDEC MS-012. It shares identical mechanical dimensions and solder pad layout with industry-standard SMB rectifiers like MURS880 or ES1J, enabling direct PCB footprint reuse.

How does RS1KB-13-F differ from RS1KB-13?

The "-F" suffix denotes Diodes Incorporated's lead-free, halogen-free "Green" construction per RoHS 3 and JEDEC J-STD-609A Class 1. RS1KB-13 (without -F) uses legacy tin-lead plating; RS1KB-13-F substitutes matte tin annealed over copper alloy, fully compliant with modern environmental regulations.

Can RS1KB-13-F be used in place of a Schottky diode?

No - RS1KB-13-F is a PN-junction fast recovery rectifier (V_F = 1.3 V, t_RR = 150 ns), not a Schottky. It lacks the low forward voltage (<0.5 V) of Schottkys but offers higher V_RRM (800 V) and better high-temperature stability. Use only where its recovery speed and blocking voltage meet design requirements.
