Product details

Overview

RS2K-13-F from Diodes Incorporated is a 1.5A surface-mount fast recovery rectifier with 800V peak repetitive reverse voltage (V_RRM), 1.3V forward voltage (V_FM) at 1.5A, and 150ns reverse recovery time (t_rr), designed for high-efficiency AC/DC input stage rectification in offline power supplies and industrial SMPS.

For engineers reviewing the RS2K-13-F datasheet, RS2K-13-F pinout, RS2K-13-F application, or RS2K-13-F equivalent, key selection criteria include its 800V blocking rating, fast 150ns recovery for reduced switching loss, 50A surge capability, SMA package thermal resistance of 20°C/W, and RoHS-compliant lead-free matte tin plating.

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 exposure, while the cathode-band polarity marking enables reliable automated placement.

The 150ns reverse recovery time (measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A) supports operation in 50–100kHz flyback and forward topologies without excessive diode turn-off loss or EMI generation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Sustains full mains-derived DC bus voltages up to 560V RMS (e.g., 400VAC industrial input) with margin
I_O	1.5 A - Continuous average output current at T_T = 120°C, suitable for 20–30W power stages
V_FM	1.3 V @ 1.5A - Low conduction loss enabling >92% efficiency in low-power offline adapters
t_rr	150 ns - Fast recovery minimizes reverse recovery charge (Q_rr) and associated switching losses
I_FSM	50 A - Withstands 8.3ms half-sine surges, supporting cold-start and lightning-induced transients
R_θJT	20 °C/W - Junction-to-terminal thermal resistance enables direct PCB copper pad heatsinking without external heatsink

Pinout & Package

RS2K-13-F is housed in the SMA (DO-214AC) surface-mount plastic package, featuring two terminals: anode and cathode, with polarity indicated by a molded cathode band on the body.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input terminal for positive half-cycle conduction	Connected to AC input or transformer secondary; must withstand full V_RRM during reverse bias
Cathode	Output terminal for rectified DC path	Connected to bulk capacitor or downstream converter; marked with visible band for orientation verification

Key Features

Feature	Design Value
Glass passivated die	Eliminates need for conformal coating in humid environments; improves long-term reliability vs. epoxy-passivated alternatives
Fast 150ns recovery	Reduces switching loss by ~40% versus standard 1μs recovery rectifiers at 65kHz operation
50A surge rating	Supports EN 61000-4-5 Level 3 (2kV line-earth) surge immunity without external clamping
RoHS & "Green" compliant	Meets Br+Cl <1500ppm, Sb <1000ppm, and Pb-free requirements for automotive and industrial end markets

Applications

AC/DC Adapter Input Stage

IC Role / Device Role / Timing Role: Primary-side unidirectional current switch converting AC to pulsating DC before bulk capacitance.

Use Value: 1.3V V_FM limits conduction loss to <2W at 1.5A, enabling thermally constrained 25mm × 25mm PCB layouts.

Use Scenario: Input rectification in 24V/1.2A industrial power modules operating in ambient temperatures up to +70°C.

IC Role / Device Role / Timing Role: High-reliability mains interface component rated for continuous operation at T_J = 125°C.

Use Value: 800V V_RRM provides 2× safety margin over 400VAC three-phase line-to-line inputs common in factory automation.

UPS Charger Input Stage

Use Scenario: Converting 120/230VAC to DC bus for constant-current LED drivers in outdoor lighting.

IC Role / Device Role / Timing Role: Line-frequency rectifier subjected to repeated thermal cycling and humidity exposure.

Use Value: Glass passivation prevents leakage current drift and parametric shift after 1000hr 85°C/85% RH testing per JESD22-A101.

Use Scenario: Input rectification in online UPS systems where battery charging occurs during utility outage.

IC Role / Device Role / Timing Role: Bidirectionally stressed component handling both normal rectification and regenerative energy during transfer events.

Use Value: 50A I_FSM withstands 10ms inrush surges from discharged bulk capacitors without degradation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L08S	Same 800V V_RRM, but 1.7V V_FM at 1.5A and 200ns t_rr; TO-277 package (lower R_θJA but larger footprint)	Higher conduction loss reduces efficiency in thermally limited adapters; preferred in forced-air-cooled UPS designs	Select when board space allows TO-277 and thermal budget permits higher V_FM
ON Semi MUR160	600V V_RRM, 1.2V V_FM, 75ns t_rr; SMB package; not rated for 800V systems	Insufficient blocking voltage for universal-input 265VAC designs; requires derating or redesign	Only suitable for 120VAC-only or 277VAC line-to-neutral applications with margin analysis

Compared with STTH1L08S and MUR160, RS2K-13-F delivers optimal balance of 800V robustness, 150ns speed, and SMA footprint-making it the preferred choice for space-constrained, universal-input offline converters where thermal management relies on PCB copper area rather than discrete heatsinks.

FAQ

What is the maximum junction temperature for RS2K-13-F?

The RS2K-13-F has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (R_θJT) is 20°C/W, meaning that at 1.5A average current and 1.3V forward drop, junction temperature rise above terminal temperature is approximately 39°C-well within safe limits when mounted on ≥5mm² copper pads.

Is RS2K-13-F qualified for automotive use?

RS2K-13-F is not AEC-Q101 qualified. While Diodes offers AEC-Q101 versions in the RS2x family (e.g., RS2KHE3_A/H), the -13-F suffix indicates commercial-grade packaging and test flow. For automotive applications, consult Diodes' AEC-Q101-certified variants and PPAP documentation.

How does RS2K-13-F differ from RS2J-13-F?

RS2K-13-F has 800V V_RRM and 150ns t_rr, whereas RS2J-13-F is rated for 600V V_RRM and 250ns t_rr. Both share identical SMA packaging and thermal characteristics, but RS2K supports higher-input-voltage systems like 400VAC industrial lines, while RS2J suits 277VAC or lower.

Can RS2K-13-F be used in place of a Schottky rectifier?

No-RS2K-13-F is a PN junction fast recovery rectifier, not a Schottky. It has higher V_FM (1.3V vs. typical 0.4–0.6V) and slower recovery than Schottkys, but supports 800V blocking-unattainable with standard Schottky technology. Use only where 800V rating and cost outweigh efficiency demands.
