Product details

Overview

RS1DB-13-F from Diodes Incorporated is a 1.0A surface-mount fast recovery rectifier in SMB package, rated for 200V peak repetitive reverse voltage (V_RRM), 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 RS1DB-13-F datasheet, RS1DB-13-F pinout, RS1DB-13-F application, or RS1DB-13-F equivalent, key selection criteria include its 200V blocking capability, 30A non-repetitive surge rating, RoHS-compliant matte tin finish, and SMB 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 bridge or output stage configurations. Its glass-passivated die construction ensures stable leakage performance across -65°C to +150°C operating range, while the 150ns t_RR enables efficient operation up to ~100kHz switching frequencies.

The SMB package provides 0.093g mass and UL 94V-0 flammability rating, with cathode band polarity marking and solderable matte tin terminals per MIL-STD-202. Thermal resistance (R_θJT = 20°C/W) supports 1.0A average current at T_T = +120°C per derating curve.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Sustains 200V reverse bias without breakdown; suitable for 170VAC input-derived rails.
I_O	1.0 A - Continuous average forward current at T_T = +120°C; requires heatsinking above ambient.
V_FM	1.3 V @ 1.0A - Low conduction loss improves efficiency in low-voltage secondary-side rectification.
t_RR	150 ns - Fast recovery minimizes switching losses and EMI in high-frequency SMPS designs.
I_FSM	30 A - Withstands 8.3ms half-sine surge; protects against line transients and inrush currents.
R_θJT	20 °C/W - Junction-to-terminal thermal resistance enables direct PCB copper pour cooling without clip.
I_RM	5.0 µA @ 25°C - Low leakage preserves standby power in energy-efficient adapters.

Pinout & Package

SMB (DO-214AA) surface-mount package: molded plastic case, UL 94V-0 rated, cathode band marked on top surface, matte tin-plated copper alloy leadframe.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to transformer secondary or switch node; must handle 1.0A DC and 30A surge peaks.
Cathode	Forward current exit / reverse blocking terminal	Marked with band; ties to output capacitor positive; reverse voltage applied here during off-state.

Key Features

Feature	Design Value
Glass passivated die	Eliminates moisture-induced leakage drift and enhances long-term reliability in humid environments.
Fast 150ns recovery	Reduces reverse recovery charge (Q_rr) to <15nC, lowering switching loss vs. standard rectifiers.
30A surge rating	Enables use without external fusing in applications subject to cold-start or lightning-induced surges.
RoHS & Halogen-free	Meets EU RoHS 3 (2015/863/EU) and "Green" requirements (<900ppm Br/Cl, <1000ppm Sb).

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR120EB	Same SMB package, 200V V_RRM, but 25ns t_RR and 1.1V V_FM; higher cost.	Better suited for >500kHz resonant converters where ultra-fast recovery is mandatory.	Select when t_RR < 50ns required; avoid if cost-sensitive or thermal margin is tight (R_θJT = 25°C/W).
Vishay VS-1EWH02-M3/5AT	SMB package, 200V V_RRM, 1.15V V_FM, 120ns t_RR; AEC-Q101 qualified.	Approved for automotive infotainment power rails requiring qualification evidence.	Choose for automotive-grade designs; not recommended for cost-driven consumer adapters.

Compared with MUR120EB and VS-1EWH02-M3/5AT, RS1DB-13-F offers optimal balance of speed (150ns), conduction loss (1.3V), and cost for industrial and consumer SMPS - without over-specifying for non-automotive use cases.

FAQ

What is the maximum junction temperature for RS1DB-13-F?

The absolute maximum junction temperature is +150°C, with continuous operation supported up to +120°C terminal temperature per the derating curve. At T_T = +120°C, it delivers full 1.0A average current; above that, current must be linearly reduced to maintain safe thermal limits.

Is RS1DB-13-F compatible with lead-free reflow soldering profiles?

Yes - RS1DB-13-F uses matte tin annealed over copper alloy leadframe and is qualified for standard IPC/JEDEC J-STD-020 Level 1 moisture sensitivity. It withstands peak reflow temperatures up to 260°C for 30 seconds without degradation.

Does RS1DB-13-F have a specified reverse recovery charge (Q_rr)?

While Q_rr is not explicitly listed in the datasheet, it can be estimated from t_RR = 150ns, I_R = 1.0A, and I_RR = 0.25A test conditions. Typical Q_rr is approximately 12–14nC, supporting efficient operation in 100–200kHz switching converters.

Can RS1DB-13-F replace RS1D-13-F in an existing SMA-based design?

No - RS1DB-13-F uses the larger SMB (DO-214AA) package versus RS1D-13-F's SMA (DO-214AC). Pad layout, thermal mass, and mounting height differ significantly; direct substitution requires PCB redesign and requalification of thermal performance.
