Product details
Overview
5KP6.0AHE3/73 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), 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 50 mA), and clamps to ≤10.3 V at 485 A peak pulse current - enabling robust overvoltage protection in automotive power supplies and industrial control inputs.
For engineers reviewing the 5KP6.0AHE3/73 datasheet, 5KP6.0AHE3/73 pinout, 5KP6.0AHE3/73 application, or 5KP6.0AHE3/73 equivalent, this device is selected for high-reliability DC bus protection where AEC-Q101 qualification, low clamping voltage, and 175 °C junction temperature capability are required - especially in switching power supply outputs, motor drive inputs, and automotive ECU power conditioning circuits.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 6.67–7.37 V breakdown range. Its glass-passivated P600 chip junction delivers fast response (<1 ns) and low incremental surge resistance, ensuring precise voltage limiting during lightning-induced transients or inductive switching spikes.
Rated for 5000 W peak pulse power (10/1000 μs), it sustains repetitive surges at 0.01 % duty cycle and derates linearly above 25 °C ambient per Fig. 2. The device is qualified to AEC-Q101, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets safe DC rail margin for 5 V systems. |
| VBR @ IT=50 mA | 6.67–7.37 V - Breakdown voltage tolerance band; defines minimum trigger threshold under standardized test conditions. |
| VC @ IPPM=485 A | ≤10.3 V - Clamping voltage under full-rated 5000 W surge; limits downstream IC stress during worst-case transients. |
| PPPM | 5000 W - Peak pulse power handling (10/1000 μs waveform); supports protection against IEC 61000-4-5 Level 4 surges. |
| IFSM | 600 A - Non-repetitive forward surge current (8.3 ms half-sine); enables crowbar-like fault clearing without device failure. |
| TJ max. | 175 °C - Maximum junction temperature; allows operation in under-hood automotive environments and high-ambient industrial enclosures. |
| Polarity | Unidirectional - Cathode-banded configuration; protects only against negative transients on positive rails or DC bias applications. |
Pinout & Package
Package: P600 molded epoxy case with glass-passivated junction; UL 94 V-0 rated; RoHS-compliant and AEC-Q101 qualified (HE3 suffix). Leads are matte tin-plated, solderable per J-STD-002, with cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge events up to 600 A. |
| Cathode | Reverse clamping terminal | Connected to protected line (e.g., +6 V rail); initiates avalanche breakdown when reverse voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock - suitable for engine control units and ADAS power stages. |
| 5000 W peak pulse power | Enables single-device protection against severe transients (e.g., ISO 7637-2 Pulse 5a) without external crowbar circuitry or fusing coordination. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage overshoot during clamping - critical for safeguarding 6 V-tolerant logic, gate drivers, and analog front-ends. |
| P600 glass-passivated junction | Provides stable, repeatable avalanche characteristics and long-term parameter stability under thermal cycling and surge stress. |
| 10/1000 μs waveform compliance | Matches IEC 61000-4-5 surge immunity test standard - ensures design-in confidence for industrial and telecom infrastructure equipment. |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive Input Stage |

IC Role / Device Role / Timing Role: Standoff-clamp device placed after secondary synchronous rectifier to limit output to ≤10.3 V during fault conditions. Use Value: Complies with UL 62368-1 transient immunity requirements while enabling compact layout due to P600's 9.5 mm body length. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A | Lower peak power (600 W), smaller SMB package, same VWM/VBR range. | Suitable for board-level ESD and low-energy transients; not rated for IEC 61000-4-5 Level 4. | Select when space-constrained layouts prioritize footprint over surge energy handling. |
| 1.5KE6.8A | Same P600 package, but lower peak power (1500 W), higher VC (11.5 V), and non-AEC-Q101. | Limited to commercial-grade industrial controls; insufficient for automotive load dump compliance. | Choose only for cost-sensitive, non-automotive applications where 5000 W rating is unnecessary. |
Compared with SMBJ6.0A and 1.5KE6.8A, the 5KP6.0AHE3/73 uniquely combines AEC-Q101 qualification, 5000 W surge capacity, and ≤10.3 V clamping - making it the sole option among the three for automotive-grade DC bus protection requiring full ISO 7637-2 compliance and thermal robustness to 175 °C.

FAQ
What is the clamping voltage of the 5KP6.0AHE3/73 under full-rated surge current?
The 5KP6.0AHE3/73 clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 485 A (10/1000 μs waveform). This value is measured per JEDEC-standard test conditions and ensures downstream components see limited overvoltage during surge events. The 5KP6.0AHE3/73 maintains this clamping performance across its specified operating temperature range.
Is the 5KP6.0AHE3/73 suitable for automotive applications?
Yes, the 5KP6.0AHE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and ADAS power stages. Its 175 °C maximum junction temperature, robust P600 package, and compliance with ISO 7637-2 load dump testing make it appropriate for under-hood and chassis-mounted applications. The HE3 suffix confirms its automotive-grade qualification status.
How does the 5KP6.0AHE3/73 differ from the 5KP6.0A-E3/73 variant?
The 5KP6.0AHE3/73 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, while the 5KP6.0A-E3/73 is commercial-grade (JESD 201 Class 1A). Both share identical electrical specs and P600 packaging, but only the HE3 version is approved for automotive applications. The 5KP6.0AHE3/73 undergoes additional stress testing including temperature cycling and mechanical shock per AEC-Q101 requirements.
What is the maximum junction temperature rating for the 5KP6.0AHE3/73?
The 5KP6.0AHE3/73 has a maximum junction temperature (TJ) of +175 °C, allowing reliable operation in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies. Derating curves in the datasheet define allowable power dissipation versus lead temperature, supporting thermal design up to this limit.
Does the 5KP6.0AHE3/73 require a heatsink for normal operation?
No heatsink is required for transient suppression duty, as the 5KP6.0AHE3/73 handles energy in short pulses (≤1000 μs) rather than continuous power. However, for sustained power dissipation, its 8.0 W rating on an infinite heatsink at TL = 75 °C applies. In typical surge-protection use, PCB copper area and lead thermal mass provide sufficient heat sinking for repetitive 0.01 % duty cycle events.
