Product details
Overview
5KP22AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 22 V stand-off voltage (VWM), 24.4–26.9 V breakdown voltage (VBR) at 5 mA, 5000 W peak pulse power (10/1000 μs), 141 A peak pulse current (IPPM), and clamps to ≤35.5 V at rated surge. It is AEC-Q101 qualified and used in automotive power supply input stages.
For engineers reviewing the 5KP22AHE3_A/C datasheet, 5KP22AHE3_A/C pinout, 5KP22AHE3_A/C application, or 5KP22AHE3_A/C equivalent, key selection criteria include clamping voltage vs. protected IC's absolute maximum rating, unidirectional polarity requirement, P600 thermal dissipation capability, and AEC-Q101 qualification for automotive under-hood use.
Technical Context
This TVS operates as a voltage-clamped crowbar device-triggering into low-impedance conduction when reverse voltage exceeds VBR, limiting transient energy delivered to downstream circuitry. Its glass-passivated P600 junction enables robust 5000 W surge handling with <1 ns response time and low incremental surge resistance.
The device is optimized for single-event transients (e.g., load dump, ISO 7637-2 Pulse 5a) rather than repetitive ESD. Thermal derating follows a defined curve: power dissipation drops from 8.0 W at TL = 75 °C to zero at TJ = 175 °C, requiring adequate PCB copper area or heatsinking for sustained surge duty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22.0 V - Maximum continuous reverse operating voltage before leakage exceeds 2 µA; sets upper limit for normal DC rail operation. |
| VBR (min/max) | 24.4 V / 26.9 V at IT = 5 mA - Confirmed breakdown range ensures reliable triggering above VWM with margin against tolerance drift. |
| VC @ IPPM | ≤35.5 V at 141 A (10/1000 μs) - Clamping voltage directly determines whether protected MOSFET or controller IC remains within safe SOA. |
| PPPM | 5000 W - Peak surge power rating defines maximum transient energy absorption without failure under standardized waveform. |
| TJ max. | +175 °C - Junction temperature limit enables placement near hot components (e.g., power inductors, regulators) in automotive modules. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per stress test plan. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; cathode indicated by color band; RoHS-compliant, AEC-Q101 qualified (HE3 suffix); UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage return path; forms clamping loop with cathode during transient event. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., battery feed); conducts surge current to anode when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Supports ISO 7637-2 Pulse 5a load dump suppression on 12 V automotive systems without external crowbar circuitry. |
| AEC-Q101 qualification | Validates long-term reliability under automotive thermal, mechanical, and electrical stress profiles-no requalification needed for Tier 1 designs. |
| Clamping voltage ≤35.5 V | Ensures protected 36 V-rated DC-DC controllers (e.g., LM5143A) remain within absolute maximum ratings during 100 V/141 A transients. |
| P600 package thermal mass | Enables 8.0 W steady-state dissipation at TL = 75 °C-supports PCB copper pour heatsinking without discrete heatsink. |
Applications
| Automotive Power Input Protection | Industrial DC Power Rail Clamping |
|---|---|
Use Scenario: 12 V battery feed to body control module exposed to ISO 7637-2 Pulse 5a (load dump up to 100 V, 400 ms). IC Role / Device Role: Primary overvoltage clamp placed between battery input and upstream fuse or DC-DC converter input. Use Value: Limits transient voltage to ≤35.5 V, preventing damage to 40 V-input buck controllers and enabling fuse-only fault clearing without system shutdown. |
Use Scenario: 24 V industrial PLC I/O power rail subject to inductive switching spikes from solenoid drivers. IC Role / Device Role: Standoff protector parallel to rail, triggered only during >24 V transients exceeding VWM. Use Value: Absorbs 5000 W surges without degradation, maintaining rail integrity while allowing downstream overcurrent protection to operate. |
| Telecom DC Feeder Protection | Consumer Power Adapter Output Clamp |
Use Scenario: -48 V telecom central office power feed exposed to lightning-induced surges on long cable runs. IC Role / Device Role: Unidirectional TVS on negative rail, referenced to chassis ground, clamping positive-going transients. Use Value: Withstands 141 A pulses while holding clamping voltage below -42 V, preserving -57 V to -40 V operational window of line cards. |
Use Scenario: 19 V output of laptop AC/DC adapter subjected to ESD and fast transient bursts during plug insertion. IC Role / Device Role: Secondary-stage clamp after primary OVP, protecting USB-PD controller and Type-C port electronics. Use Value: Fast <1 ns response prevents latch-up in 20 V-rated silicon, with low leakage (<2 µA at 22 V) avoiding standby power penalty. |
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 PPPM (600 W), smaller SMB package, same VWM/VBR range, no AEC-Q101 qualification. | Not suitable for automotive load dump; limited to low-energy ESD and inductive spikes in consumer/industrial PCBs. | Select SMBJ22A only for space-constrained, non-automotive designs where 5000 W surge capacity is unnecessary. |
| 1.5KE22A | Same P600 package and 5000 W rating, but legacy JEDEC TO-204AA outline; not AEC-Q101 qualified; higher VF (3.5 V vs. 3.5 V, identical). | Lacks automotive qualification documentation; may require additional reliability testing for automotive deployment. | Choose 1.5KE22A only for cost-sensitive industrial applications where AEC-Q101 is not mandated and legacy sourcing is preferred. |
Compared with SMBJ22A and 1.5KE22A, the 5KP22AHE3_A/C uniquely combines AEC-Q101 qualification, P600 thermal robustness, and 5000 W surge capacity-making it the only drop-in solution for automotive front-end protection without layout or reliability revalidation.

FAQ
What is the clamping voltage of the 5KP22AHE3_A/C under full-rated surge current?
The 5KP22AHE3_A/C clamps to a maximum of 35.5 V when subjected to its rated 141 A peak pulse current (IPPM) using the standard 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.
Is the 5KP22AHE3_A/C suitable for bidirectional transient protection?
No, the 5KP22AHE3_A/C is unidirectional only, with polarity marked by a cathode band. It protects against positive-going transients on the cathode side relative to anode (ground). For bidirectional protection, a separate 5KP22CA variant or back-to-back configuration is required.
Does the 5KP22AHE3_A/C meet automotive qualification standards?
Yes, the HE3 suffix confirms AEC-Q101 qualification. The 5KP22AHE3_A/C has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and surge endurance per the AEC-Q101-011 standard, making it approved for automotive under-hood and chassis applications.
What is the maximum continuous power dissipation for the 5KP22AHE3_A/C?
The 5KP22AHE3_A/C dissipates up to 8.0 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. Derating is required above this temperature-e.g., ~5.6 W at TL = 100 °C-per the power derating curve in Figure 5 of the datasheet.
How does the 5KP22AHE3_A/C differ from the base 5KP22A-E3 version?
The 5KP22AHE3_A/C includes the HE3 suffix indicating AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas the E3-suffix version is commercial-grade only. Both share identical electrical specs and P600 packaging, but only the HE3 variant is certified for automotive use.
