Product details
Overview
5KP22-E3/54 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), 22 V stand-off voltage (VWM), 24.4–26.9 V breakdown voltage (VBR at 50 mA), and clamps transients to ≤35.5 V at 141 A peak pulse current - used in automotive power supply output protection and industrial sensor interface circuits.
For engineers reviewing the 5KP22-E3/54 datasheet, 5KP22-E3/54 pinout, 5KP22-E3/54 application, or 5KP22-E3/54 equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, RoHS-compliant packaging details, and real-world design context for overvoltage protection in switching power supplies and inductive load environments.
Technical Context
The 5KP22-E3/54 operates as a unidirectional avalanche diode with glass-passivated P600 junction, optimized for fast response (<1 ns) to transient events such as ESD, lightning-induced surges, and inductive switching spikes. Its 175 °C maximum junction temperature and 8.0 W steady-state power dissipation support operation under sustained thermal stress when mounted on adequate heatsinking.
It complies with JEDEC registered test conditions (10/1000 µs waveform, 0.01% duty cycle), exhibits low incremental surge resistance, and maintains stable clamping performance across -55 °C to +175 °C operating range - enabling use in under-hood automotive electronics and industrial control systems where ambient temperatures exceed 105 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 24.4 V / 26.9 V at 50 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤35.5 V at 141 A - Clamped voltage during 5000 W transient; determines protected circuit's maximum stress level. |
| PPPM | 5000 W - Peak pulse power handling (10/1000 µs); supports robust 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 placement near hot components in power electronics enclosures. |
| Package | P600 - Axial-leaded, molded epoxy case rated UL 94 V-0; provides mechanical ruggedness and flame resistance for industrial mounting. |
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; meets JESD 201 Class 1A whisker test (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Cathode-referenced return path | Connected to ground or low-impedance return in unidirectional clamp configuration; enables surge current shunting to reference plane. |
| Cathode | Protected line connection / Surge sensing node | Connected to line being protected (e.g., +12 V rail); color band identifies this terminal; reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ22A | Lower peak power (400 W), SMA package (surface-mount), 22 V VWM, 35.5 V VC @ 11.8 A | Designed for PCB-level board-level protection; not rated for AEC-Q101 or 5000 W surges | Select for space-constrained consumer designs where surge threat level is limited to IEC 61000-4-2 ESD only. |
| ON Semiconductor 1.5KE22A | Same P600 package, 1500 W peak power, 22 V VWM, 35.5 V VC @ 42.3 A, AEC-Q101 qualified | Lower energy handling; suitable for lower-tier automotive modules or cost-sensitive industrial controls | Choose when system-level surge testing does not require full 5 kV/2 Ω IEC 61000-4-5 compliance. |
Compared with SMAJ22A and 1.5KE22A, the 5KP22-E3/54 delivers 3.3× higher peak power than 1.5KE22A and over 12× more than SMAJ22A - making it the only option among the three qualified for full-load automotive load dump and industrial 4 kV surge immunity requirements.

FAQ
What is the maximum clamping voltage of the 5KP22-E3/54 under peak surge conditions?
The 5KP22-E3/54 clamps to a maximum of 35.5 V when subjected to its rated 141 A peak pulse current (10/1000 µs waveform). This value is measured and guaranteed per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The 5KP22-E3/54 maintains this clamping performance across its full operating temperature range (-55 °C to +175 °C), with minimal drift due to its low VBR temperature coefficient of 0.100 %/°C.
Is the 5KP22-E3/54 suitable for automotive applications?
Yes, the 5KP22-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its P600 package withstands mechanical shock and thermal cycling per AEC-Q101, and its 175 °C maximum junction temperature supports operation adjacent to power converters and engine control modules. The 5KP22-E3/54 is commonly deployed on 12 V battery rails and alternator output lines to suppress load dump transients up to ISO 7637-2 Pulse 5a.
What does the "E3/54" suffix mean in 5KP22-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/54" denotes the preferred package code for 13-inch paper tape and reel delivery, with a base quantity of 800 units per reel. This ordering format ensures consistent automated assembly compatibility and traceability through Vishay's manufacturing and distribution chain.
How does the 5KP22-E3/54 differ from bidirectional TVS diodes?
The 5KP22-E3/54 is unidirectional only, meaning it conducts in reverse bias above VBR but blocks forward current up to 3.5 V at 100 A. Unlike bidirectional variants, it cannot suppress negative-going transients on AC lines or symmetric signals. Its unidirectional architecture yields lower leakage (<2 µA at 22 V), tighter VBR tolerance, and higher surge capability - making it optimal for DC power rail protection where polarity is fixed and energy levels exceed 1 kW.
Can the 5KP22-E3/54 replace a 1.5KE22A in an existing design?
No direct replacement is assured: although both share P600 packaging and 22 V VWM, the 5KP22-E3/54 delivers 5000 W peak power versus 1500 W for the 1.5KE22A - resulting in significantly higher surge current (141 A vs. 42.3 A) and different thermal mass. PCB layout, heatsinking, and fuse coordination must be re-evaluated. The 5KP22-E3/54 may require larger copper pours or additional thermal relief to manage its higher energy dissipation during clamping events.
