Product details
Overview
RS5KP5M-13 from Diodes Incorporated is an obsolete 5 A glass-passivated fast recovery rectifier in PowerDI-5 package, rated for 800 V peak repetitive reverse voltage, 1.2 V max forward voltage at 5 A, 10 µA max reverse leakage at 800 V/25°C, and 500 ns max reverse recovery time - used in AC/DC front-end rectification and high-efficiency switching power supplies.
For engineers reviewing the RS5KP5M-13 datasheet, RS5KP5M-13 pinout, RS5KP5M-13 application, or RS5KP5M-13 equivalent, key selection criteria include surge current capability (200 A IFSM), thermal resistance (2.2 °C/W RθJL on alumina), low-leakage performance at elevated temperature, and PCB-level heat-sinking via exposed underside pad.
Technical Context
The RS5KP5M-13 implements a planar junction, glass-passivated silicon die optimized for fast recovery (tRR ≤ 500 ns) and high surge tolerance (IFSM = 200 A, 8.3 ms half-sine). Its PowerDI-5 package integrates a large copper leadframe with thermally conductive underside for direct PCB heat transfer.
Electrical behavior is characterized by low VF drift over temperature (1.0 V typ at 25°C → 1.2 V max at 25°C), tight IR control (≤0.3 mA at 800 V/125°C), and stable capacitance (52 pF at 4 V/1 MHz), enabling reliable operation in offline SMPS and industrial rectifier stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands peak line transients in 400 VAC systems without breakdown. |
| IO @ TA=60°C | 5 A - Sustains continuous output in compact, convection-cooled power supplies. |
| VF Max @ 5 A | 1.2 V - Limits conduction loss to ≤6 W per device at full load, reducing thermal stress. |
| tRR Max | 500 ns - Minimizes switching losses and EMI in 50–100 kHz flyback and PFC stages. |
| IFSM (8.3 ms) | 200 A - Survives cold-start inrush and lightning-induced surges per IEC61000-4-5. |
| RθJL (Alumina) | 2.2 °C/W - Enables >3 W steady-state dissipation with <7°C junction-to-lead rise. |
| IR Max @ 800 V/125°C | 0.3 mA - Ensures minimal standby power loss in battery-backed or energy-sensitive systems. |
Pinout & Package
Package: PowerDI-5 - Surface-mount, thermally enhanced plastic package with exposed copper heat sink on underside; dimensions 6.51 × 3.966 × 1.10 mm (L × W × H); UL 94V-0 rated molding compound; matte tin annealed terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Left Pin) | Input current entry under forward bias | Electrically connected to left-side copper leadframe; must be soldered to PCB pour for thermal path. |
| Cathode (Right Pin) | Output current exit under forward bias | Electrically connected to right-side copper leadframe; forms return path with shared ground plane. |
| Underside Pad | Thermal & electrical common node | Exposed copper heatsink - requires full-solder coverage to internal ground or thermal plane for RθJL optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Eliminates moisture ingress and surface contamination risk - extends lifetime in humid or dusty environments. |
| Low IR at 125°C | 0.3 mA max reverse leakage preserves efficiency in high-ambient industrial enclosures (>85°C). |
| Fast tRR (237 ns typ) | Reduces turn-off switching loss by >40% vs. standard recovery rectifiers in 65 kHz PFC designs. |
| PowerDI-5 thermal design | 2.2 °C/W RθJL enables 3× higher power density than SMA packages at same IO rating. |
| RoHS 3 & "Green" compliant | Halogen-free (<900 ppm Br/Cl, <1000 ppm Sb) and lead-free - meets automotive and EU eco-design mandates. |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Front-end bridge rectification in 100–300 W industrial SMPS operating at 50/60 Hz input with 100–240 VAC range. IC Role / Device Role / Timing Role: Fast recovery rectifier in single-phase bridge configuration handling continuous 5 A average current and 200 A surge events. Use Value: 500 ns tRR minimizes diode recovery ringing and reduces snubber losses, improving overall system efficiency by ~1.2% at full load. |
Use Scenario: Input stage rectification in constant-current LED drivers for street lighting and high-bay fixtures. IC Role / Device Role / Timing Role: Primary-side unidirectional current path converting AC line to DC bus prior to buck/boost regulation. Use Value: 10 µA IR at 25°C ensures negligible standby current draw, critical for meeting IEC 62384 night-mode power requirements. |
| Automotive Onboard Charger (OBC) Auxiliary Supply | UPS Input Stage Protection |
Use Scenario: Auxiliary 12 V supply rectification in EV onboard chargers exposed to wide ambient (-40°C to +125°C) and transient-rich 400 VDC bus environments. IC Role / Device Role / Timing Role: Isolation rectifier feeding isolated DC/DC converter powering gate drivers and MCU peripherals. Use Value: 0.3 mA IR at 125°C prevents thermal runaway in sealed OBC enclosures, supporting AEC-Q101-compliant system qualification. |
Use Scenario: Input rectifier in online UPS systems requiring high reliability during grid instability and frequent zero-crossing interruptions. IC Role / Device Role / Timing Role: High-surge-capable rectifier absorbing repeated 200 A line surges without degradation over 10+ year service life. Use Value: 200 A IFSM rating exceeds IEEE C62.41 Cat. III surge requirements, eliminating need for external MOV coordination. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB580-E3/54 (Vishay) | Same 800 V VRRM, 5 A IO, but TO-277 package (RθJA = 75 °C/W vs. 24.5 °C/W); tRR = 35 ns faster (typ), VF = 1.15 V max. | Limited thermal performance in high-density layouts; requires larger PCB area for thermal relief. | Select when ultra-fast tRR dominates over thermal density; avoid in space-constrained industrial SMPS. |
| ES5J (ON Semiconductor) | Same PowerDI-5 footprint, 600 V VRRM (lower), 5 A IO, 1.7 V VF max, 500 ns tRR - no glass passivation. | Not suitable for 400 VAC mains; higher VF increases conduction loss by ~2.5 W at 5 A. | Acceptable only in 230 VAC-only systems with derated voltage margin; not drop-in for RS5KP5M-13's 800 V requirement. |
Compared with SB580-E3/54 and ES5J, RS5KP5M-13 delivers superior thermal management in dense layouts due to its 2.2 °C/W RθJL and robust glass passivation, making it preferable for long-life industrial and automotive auxiliary supplies despite obsolescence status.

FAQ
Is RS5KP5M-13 still in active production?
No - RS5KP5M-13 is officially obsolete and discontinued per Diodes Incorporated's DS41804 Rev. 3-4 (May 2026). Aetrix Electronics maintains limited legacy stock with full traceability and offers engineering support for migration paths to functionally aligned replacements such as the SB580-E3/54 or custom-qualified alternatives.
What is the correct PCB pad layout for thermal performance?
The PowerDI-5 package requires a minimum 10 mm² exposed copper pad connected to internal ground or thermal plane, with ≥0.5 mm solder mask opening around the underside heatsink. Per Diodes' recommended layout (DS41804 Fig. 4), X1 = 4.86 mm, Y1 = 3.36 mm, and G = 0.852 mm define the thermal pad outline - insufficient copper area raises RθJA by up to 4×.
Can RS5KP5M-13 replace standard recovery rectifiers like 1N5408?
No - RS5KP5M-13 is not a drop-in replacement for 1N5408. It has faster recovery (500 ns vs. 2000 ns), lower VF (1.2 V vs. 1.1 V at 3 A), and higher VRRM (800 V vs. 1000 V), but differs in package (PowerDI-5 vs. DO-201AD), thermal path, and surge rating (200 A vs. 30 A). Direct substitution risks thermal failure or layout incompatibility.
Does RS5KP5M-13 meet AEC-Q101 for automotive use?
RS5KP5M-13 itself is not AEC-Q101 qualified; however, Diodes states that automotive-grade versions of this family exist (e.g., with PPAP capability and IATF 16949 manufacturing). For automotive applications, engineers must request the specific AEC-Q101 variant (e.g., RS5KP5Q-13) - the -13 suffix alone does not imply qualification.
