Product details
Overview
5KP22HE3/73 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), 22 V stand-off voltage (VWM), 35.5 V maximum clamping voltage at 141 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP22HE3/73 datasheet, 5KP22HE3/73 pinout, 5KP22HE3/73 application, or 5KP22HE3/73 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, and high surge current handling are critical.
Technical Context
The 5KP22HE3/73 uses a glass-passivated P600 chip junction optimized for repetitive 10/1000 µs surge waveforms at 0.01% duty cycle. Its unidirectional polarity enables integration into DC-biased circuits without reverse conduction risk, and its 175 °C max junction temperature supports operation in under-hood automotive environments.
Clamping performance is defined by a 35.5 V maximum VC at 141 A IPPM, yielding a clamping ratio of 1.61 relative to VWM, with <2.0 µA leakage at 22 V and 0.100 %/°C VBR temperature coefficient - enabling stable protection across wide thermal ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 24.4 V / 26.9 V at 5.0 mA - Ensures reliable breakdown initiation within tight tolerance band |
| IPPM | 141 A (10/1000 µs) - Sustains high-energy transients without failure |
| VC | 35.5 V max at IPPM - Limits protected circuit voltage during surge to safe level |
| PPPM | 5000 W - Handles worst-case lightning or inductive-switching surges per industry standards |
| TJ max | 175 °C - Supports under-hood automotive and high-ambient industrial use |
| Leakage ID | ≤2.0 µA at VWM - Minimizes standby power loss in battery-powered systems |
Pinout & Package
5KP22HE3/73 is housed in a P600 axial-leaded package with cathode indicated by a color band. The device has two terminals: anode and cathode - no internal circuitry or additional pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., +24 V rail); color band identifies this end for correct PCB orientation |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply lines in engine control units (ECUs) against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients above 22 V. Use Value: Clamps 141 A surges to ≤35.5 V, preventing damage to microcontrollers and CAN transceivers rated for 36 V absolute max. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) in factory automation sensors exposed to EMI and cable coupling. IC Role / Device Role / Timing Role: Bidirectionally unused - configured as unidirectional clamp from signal line to local ground. Use Value: Sub-µA leakage preserves loop accuracy; 35.5 V clamping prevents op-amp input stage breakdown during field-induced spikes. |
| Switching Power Supply Output Protection | Telecom DC Feeder Line Protection |
Use Scenario: Secondary-side overvoltage suppression on 24 V outputs of AC/DC SMPS used in network equipment. IC Role / Device Role / Timing Role: Standoff-rated TVS connected across output capacitor to absorb flyback energy from transformer leakage inductance. Use Value: 5000 W rating absorbs multiple 10/1000 µs surges without derating; 175 °C TJ max allows mounting near hot components. | Use Scenario: DC power feed protection in remote radio heads (RRH) powered via 48 V PoE-like infrastructure. IC Role / Device Role / Timing Role: Unidirectional clamp from +48 V feed to ground, sized to survive induced lightning surges on outdoor cabling. Use Value: 141 A IPPM and 35.5 V VC meet GR-1089-CORE Level 3 telecom surge immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22AHE3/52 | Lower PPPM (600 W), smaller SMB package, same VWM/VC but higher clamping ratio (38.9 V) | Suitable only for lower-energy transients (IEC 61000-4-5 Level 2); not rated for automotive under-hood temperatures | Select when board space is constrained and surge threat level is moderate (e.g., consumer IoT gateways) |
| 1.5KE22A-E3/54 | Same P600 package, 1500 W PPPM, higher leakage (5.0 µA), non-AEC-Q101 | Lacks automotive qualification and thermal margin; limited to commercial/industrial ambient conditions | Choose for cost-sensitive industrial controls where AEC-Q101 is not required and peak surge energy is below 1.5 kW |
Compared with SMBJ22AHE3/52 and 1.5KE22A-E3/54, the 5KP22HE3/73 delivers 3.3× higher surge power handling and automotive-grade reliability - making it the sole choice for 24 V ECU power rail protection where single-event robustness and thermal endurance are non-negotiable.

FAQ
What is the clamping voltage of the 5KP22HE3/73 under maximum rated surge current?
The 5KP22HE3/73 has a maximum clamping voltage (VC) of 35.5 V when subjected to its rated 141 A peak pulse current (IPPM) using a 10/1000 µs waveform. This value is guaranteed per JEDEC test conditions and ensures downstream components see no more than 35.5 V during worst-case transients. The 5KP22HE3/73 achieves this while maintaining low incremental resistance for minimal let-through energy.
Is the 5KP22HE3/73 suitable for automotive applications?
Yes, the 5KP22HE3/73 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood automotive applications such as engine control units and body control modules. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker resistance and RoHS requirements - all verified per Vishay's qualification report for the 5KP family. The 5KP22HE3/73 meets automotive surge immunity standards including ISO 7637-2 Pulse 5a.
How does the 5KP22HE3/73 differ from the standard 5KP22A-E3/73?
The 5KP22HE3/73 differs from 5KP22A-E3/73 solely in qualification and plating: the "H" suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, while the "E3" suffix indicates RoHS-compliant matte tin plating. Electrically and dimensionally, both share identical VWM, VBR, VC, and PPPM specs. The 5KP22HE3/73 is the preferred choice for automotive designs requiring certified reliability.
What is the maximum reverse leakage current of the 5KP22HE3/73 at rated stand-off voltage?
The maximum reverse leakage current (ID) of the 5KP22HE3/73 is 2.0 µA at its rated stand-off voltage (VWM) of 22 V and TA = 25 °C. This low leakage preserves efficiency in always-on systems and avoids false triggering in high-impedance sensing circuits. Leakage remains below 5.0 µA up to 125 °C per Vishay's derating curves - confirming suitability for thermally demanding deployments of the 5KP22HE3/73.
Can the 5KP22HE3/73 be used in bidirectional configurations?
No, the 5KP22HE3/73 is unidirectional only, as explicitly stated in Vishay's datasheet. It conducts in forward bias and clamps in reverse bias - it cannot suppress positive transients on grounded lines without external circuitry. For bidirectional protection, two 5KP22HE3/73 devices must be connected in series opposing configuration, or a dedicated bidirectional TVS (e.g., 5KP22CA) should be selected. This limitation is inherent to the 5KP22HE3/73's internal structure and polarity marking.
