Diodes Incorporated S5KP5-13

Overview

S5KP5-13 from Diodes Incorporated is a 5.0A glass-passivated standard recovery rectifier in PowerDI5 surface-mount package, rated for 800V peak repetitive reverse voltage, 0.99V max forward voltage at 5A/25°C, and 10μA max reverse leakage at 800V/25°C. It delivers high-surge capability (200A IFSM) and low thermal resistance (2°C/W junction-to-lead), suited for AC/DC input rectification in industrial power supplies.

For engineers reviewing the S5KP5-13 datasheet, S5KP5-13 pinout, S5KP5-13 application, or S5KP5-13 equivalent, key selection criteria include VRRM derating above 25°C, thermal management via PCB copper area, surge current handling in bridge configurations, and compatibility with automated SMT assembly due to its RoHS-compliant matte tin finish.

Technical Context

This standard recovery rectifier uses glass-passivated die construction to ensure stable reverse blocking and low leakage across -55°C to +150°C operating range. Its 3µs typical reverse recovery time (tRR) and 50pF capacitance at 4V/1MHz support moderate-frequency switching in offline SMPS front-end stages.

The device is optimized for half-wave or full-wave bridge rectification with 20% capacitive-load current derating. Thermal performance relies on direct lead-to-PCB conduction: RθJL = 2°C/W enables efficient heat transfer when mounted on ≥2"×2" aluminum board per datasheet test condition.

FAQ

What is the maximum ambient temperature for continuous 5A operation?

At 5A average forward current, the S5KP5-13 must be operated below 75°C ambient temperature when mounted on a 2"×2" aluminum board, per Figure 5 derating curve. Above this, current must be reduced linearly to maintain junction temperature ≤150°C, considering RθJA = 23°C/W and RθJL = 2°C/W.

Is S5KP5-13 suitable for use in a full-wave bridge configuration?

Yes-S5KP5-13 is commonly used in discrete full-wave bridges. Its 800V VRRM supports 277VAC RMS input (peak ≈ 392V), providing >2× safety margin. Ensure symmetrical PCB layout and thermal coupling between all four devices to balance current sharing and prevent thermal runaway.

Does the PowerDI5 package require special PCB pad design?

Yes-the bottom-side copper thermal pad must be connected to a large, solder-mask-defined copper pour using multiple thermal vias to internal ground/power planes. Diodes recommends following their published PowerDI5 pad layout (Document #AP02004) to ensure mechanical reliability and optimal RθJA performance.

How does S5KP5-13 compare to fast recovery rectifiers in EMI-sensitive applications?

S5KP5-13's 3µs tRR generates less high-frequency ringing than ultrafast rectifiers (<100ns), reducing conducted EMI in input filters. However, its slower recovery increases switching loss above 50kHz. Use it in ≤20kHz rectifier stages where EMI filtering simplicity and surge robustness outweigh efficiency gains from faster recovery.
