Product details
Overview
5KP22A-E3/54 from Vishay General Semiconductor is a unidirectional 5000 W transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features a 22.0 V stand-off voltage (VWM), 24.4–26.9 V breakdown voltage (VBR) at 5.0 mA, clamps to ≤35.5 V at 141 A peak pulse current (IPPM), and operates across –55 °C to +175 °C junction temperature range. It is AEC-Q101 qualified and used in automotive power supply output protection.
For engineers reviewing the 5KP22A-E3/54 datasheet, 5KP22A-E3/54 pinout, 5KP22A-E3/54 application, or 5KP22A-E3/54 equivalent, key selection criteria include clamping voltage under 141 A surge, unidirectional polarity confirmation, P600 mechanical compatibility, thermal derating above 25 °C, and compliance with AEC-Q101 for automotive deployment.
Technical Context
The 5KP22A-E3/54 employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) to transient overvoltages and low incremental surge resistance. Its 10/1000 μs waveform rating supports repetitive surges at 0.01 % duty cycle, enabling robust protection in switching power supply outputs where crowbar replacement is required.
It delivers 5000 W peak pulse power with a maximum clamping voltage of 35.5 V at 141 A, while maintaining 2.0 μA max reverse leakage at 22.0 V stand-off. The device's 0.100 %/°C VBR temperature coefficient ensures stable breakdown behavior across its full operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 24 V systems. |
| VBR @ IT = 5.0 mA | 24.4–26.9 V - Measured breakdown range confirming tight tolerance for reliable turn-on during transients. |
| IPPM (10/1000 μs) | 141 A - Peak surge current capability that determines minimum fuse/breaker coordination time before device shorts. |
| VC @ IPPM | ≤35.5 V - Clamping voltage limiting downstream IC/MOSFET stress during worst-case surge events. |

Applications
| Automotive Power Supply Output Protection | Industrial 24 V DC Control Bus |
|---|---|
|
Use Scenario: Protecting the 24 V output of an automotive DC-DC converter from load dump and alternator ripple transients.

Use Scenario: Safeguarding PLC I/O modules connected to 24 V field wiring exposed to inductive switching noise. IC Role / Device Role / Timing Role: Standoff protector on power input terminals, absorbing repetitive 10/1000 μs transients induced by solenoid actuation. Use Value: Eliminates need for external crowbar circuits while maintaining system uptime after surge events due to self-resetting behavior. |
| Telecom DC Power Feeds | Renewable Energy Charge Controller Inputs |
|

Use Scenario: Protecting solar charge controller inputs from voltage spikes generated by PV array disconnect events. IC Role / Device Role / Timing Role: Bidirectional-capable alternative not applicable; 5KP22A-E3/54 serves as unidirectional clamp on positive rail relative to battery ground. Use Value: Ensures sustained operation under repeated 141 A surges typical of 1000 V open-circuit PV string transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | Lower 600 W peak power; SMC package; 35.5 V clamping at 17.1 A (not 141 A) | Suitable for low-energy signal-line protection only; insufficient for power rail surges | Select 5KP22A-E3/54 when protecting 24 V DC power rails subject to >100 A transients. |
| 1.5KE22A | Same 22 V VWM, but 1500 W rating and 35.5 V clamping at 42.5 A; DO-201 package | Limited to medium-energy applications; lacks AEC-Q101 qualification | Choose 5KP22A-E3/54 for automotive-grade 5000 W surge handling with validated reliability. |
Compared with SMBJ22A and 1.5KE22A, the 5KP22A-E3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, supports 141 A surge current with identical clamping voltage, and provides AEC-Q101 validation-making it uniquely suited for high-reliability 24 V power rail protection.

FAQ
What is the clamping voltage of the 5KP22A-E3/54 under maximum surge conditions?
The 5KP22A-E3/54 clamps to a maximum 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 across the full operating temperature range and forms the basis for downstream component voltage stress analysis in designs using the 5KP22A-E3/54.
Is the 5KP22A-E3/54 suitable for automotive applications?
Yes, the 5KP22A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its –55 °C to +175 °C operating junction temperature range, robust P600 package, and validated reliability testing make it appropriate for engine control units, body control modules, and DC-DC converters where the 5KP22A-E3/54 provides primary surge protection.
What does the "E3/54" suffix indicate in 5KP22A-E3/54?
The "E3" denotes RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker resistance, while "/54" specifies the preferred packaging code: 13-inch diameter paper tape and reel containing 800 units. This ordering format ensures traceable, standardized logistics for the 5KP22A-E3/54 in high-volume manufacturing.
How does the 5KP22A-E3/54 differ from bidirectional TVS diodes?
The 5KP22A-E3/54 is unidirectional only, meaning it conducts and clamps only during reverse-biased transients-ideal for DC power rail protection where polarity is fixed. Unlike bidirectional variants, it does not suppress surges of either polarity, so it must be installed with correct cathode orientation relative to the protected line in all 5KP22A-E3/54 deployments.
What thermal considerations apply when using the 5KP22A-E3/54 in continuous operation?
The 5KP22A-E3/54 has a 8.0 W power dissipation rating on an infinite heatsink at 75 °C lead temperature. In practice, thermal design must account for ambient temperature, PCB copper area, and airflow, as derating begins above 25 °C per Figure 2. For sustained surge duty cycles, the 5KP22A-E3/54 requires adequate mounting surface to avoid exceeding 175 °C maximum junction temperature.
