Product details
Overview
5KP8.0AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 8.0 V stand-off voltage (VWM), 13.6 V maximum clamping voltage at 368 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP8.0AHE3/54 datasheet, 5KP8.0AHE3/54 pinout, 5KP8.0AHE3/54 application, or 5KP8.0AHE3/54 equivalent, this device is selected for robust overvoltage protection in switching power supply outputs, automotive ECUs, and industrial sensor interfaces where fast response (<1 ns), low clamping ratio (VC/VWM ≈ 1.7), and high IFSM (600 A) are critical design requirements.
Technical Context
The 5KP8.0AHE3/54 uses a glass-passivated P600 chip junction optimized for repetitive 10/1000 μs surge waveforms at 0.01% duty cycle. Its unidirectional polarity enables forward-biased clamping during positive transients while blocking reverse leakage ≤150 μA at 8.0 V.
Thermal performance is defined by 8.0 W power dissipation on infinite heatsink at TL = 75 °C and a maximum junction temperature of 175 °C. The device meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability standards via molded epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin. |
| VBR @ IT | 8.89–9.83 V @ 5.0 mA - Breakdown voltage range defining turn-on threshold under standardized test current. |
| VC @ IPPM | 13.6 V @ 368 A - Clamped voltage during 5000 W surge; determines protected circuit's worst-case overvoltage exposure. |
| PPPM | 5000 W - Peak pulse power handling with 10/1000 μs waveform; defines single-event surge energy capacity. |
| IFSM | 600 A - Peak forward surge current (8.3 ms half-sine); supports crowbar-style fault clearing without device failure. |
| TJ max. | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| Polarity | Unidirectional - Cathode-band marked; provides clamping only for positive transients relative to anode. |
Pinout & Package
5KP8.0AHE3/54 is housed in a P600 axial-leaded package with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. The cathode is identified by a color band on the body. Lead length is 9.1–9.5 mm; body diameter is 9.1–9.5 mm; overall length is 25.4 mm min.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference node for clamping | Connected to system ground or lower-potential rail; establishes reference for unidirectional clamping action. |
| Cathode (banded end) | Surge current sink | Connected to protected line (e.g., +12 V rail); conducts surge current to ground when VIN exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|

| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a), improving system immunity. |
| UL 94 V-0 molding compound | Ensures flame-retardant enclosure integrity in enclosed power modules and battery management systems. |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under thermal cycling, critical for long-life automotive and industrial deployments. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs of engine control units (ECUs) against load dump (ISO 16750-2) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery rail and input filter capacitor. Use Value: Clamps transients to ≤13.6 V within nanoseconds, preventing damage to downstream LDOs and microcontrollers rated for 16 V absolute max. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) of pressure sensors in factory automation cabinets. IC Role / Device Role / Timing Role: Standoff-connected TVS on signal line referenced to local ground plane. Use Value: Limits induced surges from nearby motor drives to <14 V, preserving ADC input integrity and avoiding false trip conditions. |
| Switching Power Supply Output Clamp | Telecom Line Card Surge Suppression |
Use Scenario: Replacing crowbar SCR circuits on +48 V telecom rectifier outputs to reduce component count and improve reset behavior. IC Role / Device Role / Timing Role: Primary overvoltage clamp across output terminals, sized to absorb full short-circuit energy until fuse blows. Use Value: Withstands 600 A surge for 8.3 ms while maintaining <14 V clamp, enabling fuse coordination without latch-up or thermal runaway. |
Use Scenario: Protecting Ethernet PHY interface power pins (e.g., +3.3 V bias) on DSLAM line cards exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Localized TVS on each PHY supply rail, mounted adjacent to connector entry point. Use Value: Achieves sub-1 ns response and 13.6 V clamping, meeting GR-1089-CORE Level 3 surge immunity without adding series impedance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Lower peak power (600 W), smaller SMB package, same VWM/VC but higher clamping ratio (14.4 V @ 30 A). | Suitable for board-level signal line protection; insufficient for 5000 W load dump events. | Select SMBJ8.0A only for space-constrained, low-energy applications where PCB layout limits heat sinking. |
| 1.5KE8.0A | Same P600 package and 5000 W rating, but older 1.5KE family; VC = 13.6 V @ 368 A, no AEC-Q101 qualification. | Lacks automotive qualification; requires additional validation for vehicle deployment. | Choose 1.5KE8.0A for cost-sensitive industrial power supplies where AEC-Q101 is not mandated. |
Compared with SMBJ8.0A and 1.5KE8.0A, the 5KP8.0AHE3/54 uniquely combines AEC-Q101 qualification, 5000 W surge capability, and P600 thermal robustness-making it the only option qualified for under-hood automotive power rail protection without derating or supplemental cooling.

FAQ
What is the clamping voltage of the 5KP8.0AHE3/54 under maximum surge conditions?
The 5KP8.0AHE3/54 has a maximum clamping voltage (VC) of 13.6 V when subjected to its rated peak pulse current of 368 A (10/1000 μs waveform). This value is measured per JEDEC standards and ensures protected circuits remain below critical overvoltage thresholds during transient events. The 5KP8.0AHE3/54 maintains this clamping performance across its full operating temperature range.
Is the 5KP8.0AHE3/54 suitable for automotive applications?
Yes, the 5KP8.0AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, JESD 201 Class 2 whisker resistance, and validated performance under load dump (ISO 16750-2) and jump-start conditions make it appropriate for ECU, BCM, and ADAS power rail protection. The 5KP8.0AHE3/54 meets all required stress tests per the AEC-Q101 standard.
How does the 5KP8.0AHE3/54 differ from the 5KP8.0A-E3/54 variant?
The 5KP8.0AHE3/54 carries the HE3 suffix indicating AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the 5KP8.0A-E3/54 (E3 suffix) is RoHS-compliant commercial grade with JESD 201 Class 1A whisker testing. Both share identical electrical specs and P600 packaging, but only the 5KP8.0AHE3/54 is approved for automotive production. The 5KP8.0AHE3/54 is the preferred choice for Tier-1 suppliers.
What is the maximum reverse leakage current of the 5KP8.0AHE3/54 at rated stand-off voltage?
At its rated stand-off voltage (VWM) of 8.0 V and TA = 25 °C, the 5KP8.0AHE3/54 exhibits a maximum reverse leakage current (ID) of 150 μA. This low leakage ensures minimal power loss in standby mode and avoids interference with precision sensing circuits. Leakage remains within specification up to 125 °C ambient per derating curves in the 5KP8.0AHE3/54 datasheet.
Can the 5KP8.0AHE3/54 be used in bidirectional configurations?
No, the 5KP8.0AHE3/54 is unidirectional only, with cathode marked by a color band. It clamps positive transients relative to its anode and blocks reverse current up to VWM. For bidirectional protection, two 5KP8.0AHE3/54 devices must be connected in series opposition, or a dedicated bidirectional TVS such as 5KP8.0CA should be selected. The 5KP8.0AHE3/54 datasheet explicitly states "available in uni-directional polarity only."
