Product details
Overview
5KP5.0HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 5.0 V stand-off voltage (VWM), 6.4–7.0 V breakdown voltage (VBR) at 50 mA, 5000 W peak pulse power (10/1000 μs), 543 A peak pulse current (IPPM), and clamps to ≤9.2 V at rated surge. It is AEC-Q101 qualified and used in automotive power supply output protection.
For engineers reviewing the 5KP5.0HE3/73 datasheet, 5KP5.0HE3/73 pinout, 5KP5.0HE3/73 application, or 5KP5.0HE3/73 equivalent, key selection criteria include unidirectional polarity, P600 package thermal performance, clamping voltage margin versus protected IC VCC, IPPM derating above 25 °C, and RoHS/AEC-Q101 compliance for automotive deployment.
Technical Context
This device operates as a voltage-clamping avalanche diode with glass-passivated P600 junction. Its response time is sub-nanosecond, and it exhibits low incremental surge resistance (dynamic impedance < 0.017 Ω), enabling effective suppression of fast transients induced by inductive switching or ESD events.
The 5KP5.0HE3/73 is rated for 175 °C maximum junction temperature and supports repetitive surge duty cycles up to 0.01 % (4 pulses/minute). Its 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C defines thermal design limits for sustained fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before conduction begins; must exceed system nominal rail voltage. |
| VBR @ IT = 50 mA | 6.4–7.0 V - Measured breakdown range; ensures reliable turn-on before downstream component damage threshold. |
| VC @ IPPM | ≤9.2 V - Clamped voltage at 543 A peak pulse; determines maximum stress on protected load during surge. |
| IPPM | 543 A - Peak surge current capability with 10/1000 μs waveform; defines single-event energy handling capacity. |
| PPPM | 5000 W - Peak pulse power rating; sets upper bound for transient energy absorption without failure. |
| TJ max. | 175 °C - Maximum junction temperature; constrains PCB copper area, heatsinking, and ambient operating envelope. |
| Package | P600 - Axial-lead, molded epoxy case with UL 94 V-0 rating; enables manual or wave soldering per JESD 22-B106. |
Pinout & Package
P600 package: axial-leaded, cylindrical epoxy body with cathode band marking. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102. Dimensions: 9.5 mm length × 5.6 mm diameter (0.375" × 0.220").
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; carries full surge current during clamping event. |
| Cathode | High-side connection point | Connected to protected line (e.g., +5 V rail); color band identifies this terminal for correct orientation. |
Key Features
| Feature | Design Value |

| 175 °C max junction temperature | Enables operation in engine control units (ECUs), power converters, and other high-ambient environments. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Output |
|---|---|
Use Scenario: Protecting 5 V microcontroller power input in engine control unit (ECU) against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between VCC and GND, clamping transients before they reach MCU VDD pins. Use Value: Limits voltage to ≤9.2 V during 543 A surge, preserving MCU functionality and avoiding latch-up or gate oxide damage. |
Use Scenario: Safeguarding output of 5 V/10 A switching power supply feeding PLC I/O modules. IC Role / Device Role / Timing Role: Primary overvoltage clamp on secondary-side DC bus, replacing crowbar circuits per application note. Use Value: Absorbs 5000 W transient energy while allowing fuse coordination-enabling resettable protection without component replacement. |
| Telecom Line Interface Protection | Consumer Sensor Signal Line Protection |
Use Scenario: Shielding RS-485 transceiver VCC pin from induced surges on long cable runs in base station backhaul links. IC Role / Device Role / Timing Role: Standoff-rated TVS on 5 V bias rail, triggered only during >6.4 V transients exceeding normal signaling swing. Use Value: Sub-ns response prevents transceiver latch-up; clamping at 9.2 V avoids exceeding absolute maximum ratings of MAX13487 or similar ICs. |
Use Scenario: Securing I²C SDA/SCL lines of automotive cabin temperature sensor exposed to board-level ESD and harness coupling. IC Role / Device Role / Timing Role: Low-capacitance (typ. 1100 pF at 0 V) unidirectional clamp on 3.3–5 V logic rails, oriented to protect against positive-going transients. Use Value: Maintains signal integrity below 1 MHz while limiting ESD-induced voltage to safe levels for ASIL-B sensor ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0AHE3/52 | Lower PPPM (600 W), smaller SMB package, lower IPPM (102 A), same VWM/VBR tolerance. | Not suitable for ISO 7637-2 Pulse 5a (load dump); limited to board-level ESD and lower-energy transients. | Select when space-constrained layout and lower surge threat level permit reduced power rating. |
| 1.5KE5.0A | Same P600 package but lower PPPM (1500 W), higher VC (11.6 V), non-AEC-Q101, commercial-grade only. | Lacks automotive qualification and thermal robustness; unsuitable for under-hood deployment or high-reliability systems. | Acceptable for cost-sensitive consumer power supplies where AEC-Q101 and 5 kW rating are not required. |
Compared with SMBJ5.0AHE3/52 and 1.5KE5.0A, the 5KP5.0HE3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, tighter clamping (9.2 V vs. 11.6 V), and AEC-Q101 validation-making it the sole choice for automotive load-dump protection and industrial 5 kW surge immunity.

FAQ
What is the maximum clamping voltage of the 5KP5.0HE3/73 under rated surge conditions?
The 5KP5.0HE3/73 clamps to a maximum of 9.2 V when subjected to its rated 543 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The low clamping ratio (VC/VBR ≈ 1.33) reflects its optimized avalanche junction for minimal dynamic impedance.
Is the 5KP5.0HE3/73 suitable for bidirectional transient protection?
No, the 5KP5.0HE3/73 is unidirectional only, as confirmed in the Vishay datasheet "FEATURES" section. It conducts only during positive voltage excursions relative to its cathode. For bidirectional protection (e.g., AC lines or differential signals), a pair of 5KP5.0HE3/73 devices in series-opposing configuration-or a dedicated bidirectional TVS such as 5KP5.0CA-is required.
Does the 5KP5.0HE3/73 meet automotive qualification standards?
Yes, the HE3 suffix explicitly denotes AEC-Q101 qualification per the Vishay datasheet's Mechanical Data section and Notes table. This includes stress testing for temperature cycling, high-temperature operating life, unbiased high-humidity bias, and mechanical shock-validating suitability for automotive under-hood and chassis-mounted applications.
What is the thermal derating behavior of the 5KP5.0HE3/73 above 25 °C ambient?
The 5KP5.0HE3/73 follows a linear derating curve starting at 25 °C: peak pulse power decreases by approximately 0.5 %/°C above TA = 25 °C, per Figure 2 in the datasheet. At 100 °C ambient, its usable PPPM drops to ~3750 W. Steady-state power dissipation (PD = 8.0 W) also derates linearly to zero at TJ = 175 °C.
How does the P600 package of the 5KP5.0HE3/73 compare to DO-201AE in thermal performance?
The P600 package offers significantly higher thermal mass and lower thermal resistance than DO-201AE: RθJA is ~35 °C/W (vs. ~65 °C/W for DO-201AE), enabling 5KP5.0HE3/73 to sustain higher average power and dissipate 5000 W surges more reliably. Its larger body (9.5 mm × 5.6 mm) and axial leads support wave soldering and improved board-level heat spreading.
