Product details
Overview
5KP40AHE3_A/C from Vishay General Semiconductor is a unidirectional 5000 W transient voltage suppressor (TVS) diode in P600 package, with 40 V stand-off voltage (VWM), 44.4–49.1 V breakdown voltage (VBR), and 64.5 V clamping voltage (VC) at 77.5 A peak pulse current. It protects power supply outputs and automotive sensor signal lines against lightning and inductive switching transients.
For engineers reviewing the 5KP40AHE3_A/C datasheet, 5KP40AHE3_A/C pinout, 5KP40AHE3_A/C application, or 5KP40AHE3_A/C equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal derating curves, P600 mechanical dimensions, and direct alternatives for overvoltage protection design-in.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (44.4–49.1 V at 5 mA). Its low incremental surge resistance and fast response time enable effective clamping of 10/1000 μs transients up to 5000 W without thermal runaway.
Designed for high-energy surge suppression, it sustains 500 A non-repetitive forward surge current (8.3 ms half-sine) and operates from –55 °C to +175 °C junction temperature. The P600 epoxy package provides UL 94 V-0 flammability rating and matte tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 40 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 44.4 V / 49.1 V - breakdown occurs within this range at 5 mA test current, defining turn-on threshold |
| VC @ IPPM | 64.5 V - clamped voltage during 77.5 A 10/1000 μs transient, limiting downstream stress |
| PPPM | 5000 W - peak pulse power handling capability under standardized 10/1000 μs waveform |
| IFSM | 500 A - withstands 8.3 ms single half-sine surge, enabling fuse/breaker coordination |
| TJ max. | +175 °C - extended junction temperature rating supports under-hood automotive use |
| AEC-Q101 | Qualified - validated for automotive-grade reliability per stress test requirements |
Pinout & Package
P600 package: axial-leaded, molded epoxy body with cathode band marking; 9.5 mm body length, 1.32 mm lead diameter; UL 94 V-0 rated; RoHS-compliant HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to lower-potential side (e.g., ground or return) in unidirectional TVS configuration |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 40 V rail); color band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Handles high-energy transients (e.g., ISO 7637-2 Pulse 5a) without failure |
| 64.5 V clamping at 77.5 A | Ensures downstream ICs rated for ≤65 V are not overstressed during surge events |
| AEC-Q101 qualified | Validated for automotive environments including temperature cycling, HTRB, and ESD |
| P600 glass-passivated junction | Provides stable VBR and low leakage (<2 μA at 40 V) across lifetime and temperature |
| Matte tin-plated leads | Guarantees solderability per J-STD-002 and prevents whisker growth (JESD 201 Class 2) |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 40 V. Use Value: Withstands 5000 W pulses while maintaining clamping below 65 V, preserving MCU and CAN transceiver integrity. | Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) of pressure/temperature sensors in factory automation. IC Role / Device Role / Timing Role: Standoff-connected TVS on signal line to ground, absorbing ESD and switching noise. Use Value: Sub-μs response limits voltage overshoot to <65 V, preventing op-amp input stage damage during relay coil de-energization. |
| Telecom DC Power Input Protection | Switching Power Supply Output Clamping |
Use Scenario: Safeguarding PoE-powered equipment inputs against induced surges on outdoor Ethernet runs. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 48 V DC input, upstream of DC-DC converter. Use Value: 5000 W rating absorbs multi-kV lightning-induced surges; AEC-Q101 grade ensures long-term field reliability. | Use Scenario: Replacing crowbar circuits on 40 V SMPS outputs to avoid destructive short-circuit shutdown. IC Role / Device Role / Timing Role: Voltage-clamping element that diverts surge current while allowing system reset after fault clearance. Use Value: Enables automatic recovery post-transient-no fuse replacement or breaker reset required-reducing maintenance downtime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40AHE3/52 | 600 W rating, SMC package, same VWM/VBR but lower PPPM and IPPM (32.4 A) | Suitable for lower-energy transients (IEC 61000-4-5 Level 3), not load dump | Select when board space is constrained and surge energy is ≤600 W |
| 15KPA40A | 15 kW rating, P600 package, higher VC (72.7 V), same VWM, AEC-Q101 qualified | Better suited for extreme transients (e.g., ISO 16750-2 12 V vehicle tests) | Choose when clamping margin allows ≥72 V and system must survive >5 kV surges |
Compared with SMBJ40AHE3/52 and 15KPA40A, the 5KP40AHE3_A/C delivers optimal balance of 5000 W surge capacity, 64.5 V clamping, and AEC-Q101 compliance in standard P600 through-hole format-ideal for cost-sensitive automotive and industrial power rail protection where 15 kW is excessive and 600 W insufficient.

FAQ
What is the clamping voltage of the 5KP40AHE3_A/C and how is it measured?
The 5KP40AHE3_A/C has a maximum clamping voltage (VC) of 64.5 V, measured at 77.5 A peak pulse current using a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a standardized surge event and is guaranteed per JEDEC test conditions in the Vishay datasheet document 88308.
Is the 5KP40AHE3_A/C suitable for automotive applications?
Yes, the 5KP40AHE3_A/C is AEC-Q101 qualified and explicitly rated for automotive use. Its –55 °C to +175 °C operating temperature range, P600 package robustness, and 5000 W surge capability meet requirements for engine control units, body electronics, and ADAS sensor power rails per ISO 7637-2 and ISO 16750-2 standards.
What does the "HE3_A/C" suffix mean in 5KP40AHE3_A/C?
The "HE3" suffix indicates RoHS compliance and AEC-Q101 qualification; "_A/C" denotes the packaging variant-"C" stands for 13-inch paper tape and reel with 800-unit base quantity. The full part number 5KP40AHE3_A/C uniquely identifies this AEC-Q101-qualified, reel-packed version of the 40 V TVS diode.
How does the 5KP40AHE3_A/C compare to bidirectional TVS diodes?
The 5KP40AHE3_A/C is unidirectional only, optimized for DC power line protection where polarity is fixed. Unlike bidirectional variants, it offers lower leakage (<2 μA at 40 V) and tighter VBR tolerance, making it preferable for 40 V rail clamping-bidirectional versions would conduct during normal reverse bias and are unsuited for this application.
Can the 5KP40AHE3_A/C replace a fuse or circuit breaker?
No-the 5KP40AHE3_A/C does not replace fuses or breakers but works alongside them. It clamps overvoltages to protect downstream components while allowing time for the fuse to blow or breaker to trip. Its 500 A IFSM rating supports coordination with standard automotive fuses, enabling safe, resettable surge protection without immediate hardware destruction.
