Product details

Overview

RS1K-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode with 800 V peak repetitive reverse voltage, 1.0 A average rectified output current, and 150 ns maximum reverse recovery time. It features glass passivated die construction, 30 A non-repetitive peak forward surge capability, and RoHS-compliant lead-free finish - used in AC/DC front-end rectification for switch-mode power supplies.

For engineers reviewing the RS1K-13-F datasheet, RS1K-13-F pinout, RS1K-13-F application, or RS1K-13-F equivalent, key selection criteria include reverse voltage rating (800 V), fast recovery performance (t_RR ≤ 150 ns), thermal resistance (20 °C/W), surge robustness (30 A @ 8.3 ms), and SMA package compatibility with automated assembly.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for high-frequency switching applications. Its fast recovery characteristic (150 ns) minimizes switching losses during turn-off, while the 800 V V_RRM supports universal input (85–265 V_AC) offline SMPS designs.

The SMA package provides low thermal resistance (R_θJT = 20 °C/W) and enables efficient heat transfer to the PCB. Reverse leakage remains ≤5.0 µA at 25 °C and ≤200 µA at 125 °C under rated blocking voltage, ensuring stable operation across industrial temperature ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Withstands peak reverse transients in 400 V DC bus or 230 V AC line applications without breakdown.
I_O	1.0 A @ T_T = +120 °C - Sustains continuous forward conduction in compact, thermally constrained layouts.
t_RR	150 ns - Reduces reverse recovery charge (Q_rr) and associated switching loss in 50–500 kHz converters.
V_FM	1.3 V @ I_F = 1.0 A - Limits forward conduction loss to ≤1.3 W at full load, supporting efficiency-critical designs.
I_FSM	30 A @ 8.3 ms - Survives cold-start inrush and lightning-induced surges per IEC 61000-4-5 Level 3.
R_θJT	20 °C/W - Enables direct PCB copper pour heatsinking without external thermal pads or vias in most cases.

Applications

AC/DC Adapter Front-End

LED Driver Input Rectification

Use Scenario: 12 V/2 A universal-input wall adapter with 50–100 kHz flyback topology.

IC Role / Device Role / Timing Role: Primary-side unidirectional current valve converting AC line to pulsating DC before the transformer.

Use Value: 150 ns t_RR limits switching loss and improves efficiency by ≥0.8% over standard 1N4007-based designs.

Use Scenario: Outdoor LED streetlight driver operating from 220 V AC with active PFC stage.

IC Role / Device Role / Timing Role: Bridge leg diode in discrete bridge configuration feeding boost PFC controller input.

Use Value: 800 V V_RRM ensures margin against line surges up to 1.2 kV, meeting EN 61000-4-5 immunity requirements.

Industrial Power Supply Input Stage

USB-C PD Charger Secondary Rectification

Use Scenario: 24 V/10 A DIN-rail mounted industrial SMPS with wide ambient range (−40 to +70 °C).

IC Role / Device Role / Timing Role: Output rectifier in forward converter secondary, handling continuous 10 A DC with synchronous FET assist.

Use Value: R_θJT = 20 °C/W allows direct mounting on 2 oz copper plane, eliminating thermal interface material.

Use Scenario: 60 W USB-C PD charger using QR flyback with secondary-side synchronous rectification.

IC Role / Device Role / Timing Role: Freewheeling clamp diode across synchronous rectifier MOSFET body diode during dead-time.

Use Value: Low 1.3 V V_FM prevents cross-conduction shoot-through and reduces gate drive stress on SR controller.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R08	Same 800 V V_RRM, but t_RR = 125 ns; higher V_FM = 1.5 V @ 1 A.	Better recovery speed but higher conduction loss; requires tighter thermal design.	Preferred where EMI reduction outweighs efficiency penalty.
ON Semiconductor MUR108	Same 800 V rating, t_RR = 75 ns, but SMB package (larger footprint, lower current density).	Lower thermal resistance (15 °C/W), but incompatible with SMA land pattern.	Select only if board redesign accommodates SMB pad layout and space.

Compared with STTH1R08 and MUR108, RS1K-13-F delivers optimal balance of speed (150 ns), conduction loss (1.3 V), and SMA footprint - making it ideal for space-constrained, cost-sensitive 1 A rectification where thermal management relies on PCB copper area rather than heatsinks.

FAQ

What is the maximum junction temperature for RS1K-13-F?

The absolute maximum junction temperature is +150 °C, with continuous operation rated up to +120 °C terminal temperature. Derating begins above +120 °C per Figure 1 in the datasheet, where average forward current drops linearly to zero at +150 °C.

Is RS1K-13-F suitable for use in a full-wave bridge configuration?

Yes - RS1K-13-F is commonly used as one quadrant in discrete full-wave bridge rectifiers. Its 800 V V_RRM supports 400 V DC bus applications, and its 30 A I_FSM rating handles bridge-level surge currents when paired with appropriate fusing.

Does RS1K-13-F have a specified reverse recovery charge (Q_rr)?

No Q_rr value is published in the DS15002 datasheet. However, Q_rr can be estimated from t_RR = 150 ns and I_R = 1.0 A (per test condition Note 7), yielding Q_rr ≈ 75 nC - useful for loss modeling in high-frequency flyback or LLC topologies.

Can RS1K-13-F replace RS1J-13-F in an existing design?

Yes - RS1K-13-F (800 V) is a direct upgrade from RS1J-13-F (600 V) with identical SMA package, pinout, and thermal characteristics. No layout or thermal changes are needed, and the higher V_RRM improves surge margin without increasing forward loss.
