Product details
Overview
5KP10HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on power rails and signal lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 50 mA, 5000 W peak pulse power (10/1000 μs), 294 A peak pulse current (IPPM), and 17.0 V maximum clamping voltage (VC) - used to protect MOSFETs and ICs in automotive power supplies.
For engineers reviewing the 5KP10HE3/73 datasheet, 5KP10HE3/73 pinout, 5KP10HE3/73 application, or 5KP10HE3/73 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, RoHS-compliant HE3 suffix with JESD 201 Class 2 whisker resistance, and P600 package thermal performance under repetitive surge conditions.
Technical Context
The 5KP10HE3/73 uses a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling precise clamping during inductive load switching transients. Its unidirectional structure provides forward conduction capability up to 600 A IFSM (8.3 ms half-sine), supporting crowbar-replacement designs in DC power outputs.
Thermal derating follows JEDEC curves: power dissipation drops from 8.0 W at TL = 75 °C to zero at TJ = 175 °C, requiring adequate heatsinking for sustained surge events. The device meets UL 94 V-0 flammability and is rated for -55 °C to +175 °C operating junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - maximum continuous reverse voltage before clamping begins; sets operating margin above nominal 9–10 V rail |
| VBR min/max | 11.1 V / 12.3 V at 50 mA - defines guaranteed breakdown threshold for design margining |
| VC @ IPPM | 17.0 V - clamping voltage at 294 A peak pulse; limits downstream voltage stress during surge |
| PPPM | 5000 W (10/1000 μs) - energy-handling capacity for lightning or EFT immunity compliance |
| IFSM | 600 A (8.3 ms half-sine) - supports single-event overcurrent without fuse tripping delay |
| TJ max | +175 °C - enables use in under-hood automotive environments with minimal thermal derating |
| Polarity | Unidirectional - allows forward conduction for crowbar-style fault clearing in DC systems |
Pinout & Package
P600 package: molded epoxy body with matte tin-plated leads; cathode denoted by color band; RoHS-compliant HE3 suffix indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current path / surge return path | Connected to ground or low-side reference; carries full IPPM during clamping |
| Cathode | Protected line connection / clamping node | Connected to rail being protected (e.g., 12 V battery line); voltage clamped to ≤17.0 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10AHE3/52 | Lower PPPM (600 W), smaller SMB package, same VWM (10 V), higher VC (17.0 V) | Rated for lower-energy transients; suited for PCB-level signal line protection, not bulk power rail clamping | Select when space-constrained and surge energy <100 mJ; not suitable for ISO 7637-2 load dump. |
| 1.5KE10A-E3/54 | Same VWM (10 V), lower PPPM (1500 W), DO-201 package, non-AEC-Q101 | Lacks automotive qualification and thermal robustness; limited to commercial-grade power supplies | Choose for cost-sensitive consumer products where AEC-Q101 and 5 kW rating are unnecessary. |
Compared with SMBJ10AHE3/52 and 1.5KE10A-E3/54, the 5KP10HE3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, maintains AEC-Q101 qualification for automotive deployment, and uses the thermally superior P600 package - making it the only option among the three capable of surviving repeated load dump events without parameter shift.

FAQ
What is the clamping voltage of the 5KP10HE3/73 under peak surge conditions?
The 5KP10HE3/73 has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 294 A, measured with a 10/1000 μs waveform. This value ensures downstream components see no more than 17.0 V during surge events, critical for protecting 12 V-rated ICs and MOSFETs. The clamping performance is guaranteed across the full operating temperature range.
Is the 5KP10HE3/73 qualified for automotive applications?
Yes, the 5KP10HE3/73 is AEC-Q101 qualified, as confirmed by its HE3 suffix and Vishay documentation. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance required for automotive powertrain and body electronics. This makes the 5KP10HE3/73 suitable for under-hood and chassis-mounted modules subject to ISO 7637-2 load dump.
What does the 'HE3' suffix mean in 5KP10HE3/73?
The 'HE3' suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike standard 'E3' parts, 'HE3' devices meet automotive reliability standards including enhanced lead finish durability and extended thermal cycling performance - essential for long-life deployments in 5KP10HE3/73 applications.
Can the 5KP10HE3/73 replace a crowbar circuit in DC power supplies?
Yes, the 5KP10HE3/73 is explicitly designed to replace crowbar circuits in switching power supplies, as stated in Vishay's application notes. Its unidirectional architecture allows forward conduction during overvoltage, triggering upstream fuses or breakers while limiting voltage to 17.0 V - enabling safe reset without component replacement, unlike traditional SCR-based crowbars.
What is the thermal derating behavior of the 5KP10HE3/73 above 75 °C?
The 5KP10HE3/73 derates linearly from 8.0 W at TL = 75 °C to zero at TJ = 175 °C, per Figure 5 in the Vishay datasheet. At 125 °C lead temperature, its power dissipation drops to approximately 4.0 W. Designers must ensure adequate copper area or heatsinking to maintain junction temperature below 175 °C during repetitive surges, especially in enclosed automotive enclosures.
