Product details
Overview
5KP160AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on power rails and signal lines. It features 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR), 5000 W peak pulse power (10/1000 μs), 259 V clamping voltage at 19.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP160AHE3_A/C datasheet, 5KP160AHE3_A/C pinout, 5KP160AHE3_A/C application, or 5KP160AHE3_A/C equivalent, this part is selected for robust overvoltage protection in DC power supplies, automotive ECUs, industrial motor drives, and telecom line interfaces where fast response (<1 ns), low clamping ratio, and high surge current handling are critical.
Technical Context
The 5KP160AHE3_A/C uses a glass-passivated P600 chip junction optimized for unidirectional clamping with low incremental surge resistance and excellent thermal stability up to TJ = 175 °C. Its 10/1000 μs waveform rating reflects standardized IEC 61000-4-5 surge immunity testing conditions.
Designed for crowbar-replacement applications, it operates in avalanche breakdown mode during transients, maintaining stable clamping performance across temperature (−55 °C to +175 °C) and supporting repetitive surge duty cycles ≤ 0.01 % - enabling fuse/breaker coordination without device failure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before leakage exceeds 2 μA; defines safe DC bias margin for protected circuit. |
| VBR min/max | 178 V / 197 V at 5 mA - guaranteed avalanche onset range; ensures predictable turn-on under surge conditions. |
| VC @ IPPM | 259 V at 19.3 A - clamped voltage during full-rated 5000 W transient; determines worst-case overvoltage seen by downstream components. |
| PPPM | 5000 W (10/1000 μs) - peak surge energy handling capacity; supports IEC 61000-4-5 Level 4 compliance when properly mounted. |
| TJ max | +175 °C - maximum junction temperature; enables operation in under-hood automotive environments and high-ambient industrial settings. |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTOL, TCT, and ESD; suitable for ECU, ADAS, and body control modules. |
| IFSM | 500 A (8.3 ms half-sine) - non-repetitive forward surge rating; allows safe handling of inrush or fault currents without bond wire fusing. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; cathode indicated by color band; RoHS-compliant HE3 suffix denotes AEC-Q101 qualification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or surge clamping | Connected to lower-potential side (e.g., ground or return path); must be routed with low-inductance trace for effective clamping. |
| Cathode | Current exit point during reverse-biased transient suppression | Connected to protected line (e.g., 12 V rail); polarity band identifies this terminal; reversal causes permanent failure. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against severe lightning-induced surges per IEC 61000-4-5, reducing need for cascaded TVS stages. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream MOSFETs, ICs, and sensors during transient events. |
| AEC-Q101 qualified | Validated for automotive under-hood use with extended temperature cycling, humidity, and mechanical shock reliability. |
| P600 package with 2.776 g unit weight | Provides high thermal mass and PCB pad area for efficient heat dissipation during repetitive surges. |
| 175 °C max junction temperature | Supports operation in sealed enclosures or near heat-generating components without derating penalties. |
Applications
| Automotive Power Rail Protection | Industrial DC Motor Drive Inputs |
|---|---|
|

| Telecom Line Interface Protection | Switching Power Supply Output Clamping |
|
Use Scenario: Shielding PoE-powered Ethernet ports and base station RF front-end supplies from induced lightning surges. IC Role / Device Role / Timing Role: Primary-level TVS on 48 V DC input, coordinated with secondary GDT or MOV for staged protection. Use Value: Low 2 μA leakage at 160 V preserves efficiency; 259 V clamping prevents latch-up in PMICs and Ethernet PHYs. |
Use Scenario: Replacing crowbar circuits on SMPS outputs to avoid destructive short-circuit shutdown during overvoltage faults. IC Role / Device Role / Timing Role: Voltage-clamping element that diverts excess energy to ground while allowing breaker/fuse time to interrupt. Use Value: Enables system reset without component replacement-critical for remote or mission-critical power systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ160A | Same 160 V VWM, but 400 W PPPM (SMA package); lower surge capacity and thermal mass. | Suitable for low-energy signal-line protection; insufficient for ISO 7637-2 load dump or IEC 61000-4-5 Level 4. | Select 5KP160AHE3_A/C when ≥5000 W surge handling and AEC-Q101 qualification are required. |
| ON Semiconductor 1.5KE160A | Same 160 V VWM and 5000 W rating, but TO-204AA (DO-204AB) package; no AEC-Q101 qualification; higher thermal resistance. | Acceptable for commercial/industrial power supplies; not approved for automotive under-hood deployment. | Choose 5KP160AHE3_A/C for automotive OEM programs requiring documented AEC-Q101 compliance and P600 thermal performance. |
Compared with SMAJ160A and 1.5KE160A, the 5KP160AHE3_A/C delivers superior surge endurance, automotive-grade reliability, and lower thermal impedance-making it the preferred choice for high-reliability DC power rail protection where long-term field stability is mandatory.

FAQ
What is the clamping voltage of the 5KP160AHE3_A/C at its rated peak pulse current?
The 5KP160AHE3_A/C has a maximum clamping voltage (VC) of 259 V at its rated peak pulse current (IPPM) of 19.3 A, measured under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during a full-rated surge event and is confirmed in the Vishay datasheet Document Number 88308, Table on page 2.
Is the 5KP160AHE3_A/C suitable for automotive applications?
Yes, the 5KP160AHE3_A/C is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its P600 package, 175 °C max junction temperature, and validation across temperature cycling, humidity, and mechanical stress make it appropriate for ECUs, ADAS modules, and body control units per OEM requirements.
What does the "HE3_A/C" suffix indicate in 5KP160AHE3_A/C?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "_A/C" specifies the revision code and packaging format - C indicates 13-inch paper tape and reel with 800 units per reel, per Vishay's ordering information table on page 3 of document 88308.
How does the 5KP160AHE3_A/C differ from the standard 5KP160A-E3 variant?
The 5KP160AHE3_A/C is identical in electrical specifications to the 5KP160A-E3 but adds AEC-Q101 qualification, enhanced whisker resistance (JESD 201 Class 2), and tighter process controls for automotive reliability. The "HE3" suffix replaces "E3" to reflect this upgraded qualification status and material compliance.
Can the 5KP160AHE3_A/C be used in bidirectional configurations?
No, the 5KP160AHE3_A/C is unidirectional only, as stated in the Vishay datasheet features section. It conducts in forward bias and clamps in reverse bias; using it in bidirectional applications requires pairing with another diode or selecting a dedicated bidirectional TVS such as the 5KP160CA series.
