Diodes Incorporated S5KP5M-13

Overview

S5KP5M-13 from Diodes Incorporated is a 5.0A glass-passivated standard recovery rectifier in PowerDI5 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; used in AC/DC front-end rectification for industrial power supplies and auxiliary rails.

For engineers reviewing the S5KP5M-13 datasheet, S5KP5M-13 pinout, S5KP5M-13 application, or S5KP5M-13 equivalent, key selection criteria include surge current capability (200A IFSM), thermal resistance (2°C/W junction-to-lead), low-leakage performance across temperature, and RoHS-compliant "Green" packaging for automotive-qualified designs.

Technical Context

This standard recovery rectifier features glass-passivated die construction for enhanced reliability under high-voltage transients and thermal cycling. Its 3µs typical reverse recovery time (tRR) and 50pF junction capacitance support moderate-speed switching in offline SMPS and hold-up rectifiers.

The device operates from –55°C to +150°C with derated forward current above 75°C ambient, and exhibits 0.3mA IR at 800V/125°C - critical for high-temperature power conversion stages where leakage-induced losses must be minimized.

FAQ

What is the maximum junction temperature for continuous operation?

The S5KP5M-13 has an operating junction temperature range of –55°C to +150°C. For continuous operation at full 5A average current, thermal design must maintain TJ ≤150°C - typically achieved using ≥2″×2″ aluminum PCB or external heatsinking per the datasheet's RθJA = 23°C/W condition.

Is the S5KP5M-13 qualified for automotive use?

The S5KP5M-13 is not pre-qualified to AEC-Q101, but Diodes offers automotive-grade variants (e.g., S5KP5M-AQ) with PPAP documentation, IATF 16949 manufacturing, and extended test coverage. Standard S5KP5M-13 may be used in non-safety-critical automotive auxiliary functions pending customer qualification.

How does the PowerDI5 package improve thermal performance over SMA/SMB?

The PowerDI5 package features an exposed bottom-side metal pad that serves as both thermal path and cathode connection, achieving RθJL = 2°C/W - roughly 3× better than SMA (RθJL ≈ 6°C/W). This reduces junction temperature rise by up to 40°C at 5A, improving reliability and enabling higher power density layouts.

Can S5KP5M-13 replace older DO-201AD rectifiers in existing designs?

Yes - the S5KP5M-13 provides identical 800V/5A ratings and improved thermal performance versus DO-201AD parts like 1N5408. However, the PowerDI5 footprint differs: pad layout must be updated to match 6.5mm × 4.0mm body size and 1.84mm pitch; no rework adapter is required, but PCB revision is necessary.
