Product details
Overview
5KP22HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on 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 (VC) at 141 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP22HE3/54 datasheet, 5KP22HE3/54 pinout, 5KP22HE3/54 application, or 5KP22HE3/54 equivalent, this part is selected for robust overvoltage protection in DC power supplies, automotive ECUs, industrial motor drives, and telecom interface circuits where fast response (<1 ns), low clamping ratio, and high surge current handling are critical.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during transients - it remains high-impedance below VWM = 22 V and avalanches sharply above VBR = 24.4–26.9 V (at 50 mA), limiting voltage to ≤35.5 V at 141 A. Its P600 glass-passivated junction enables stable breakdown with 0.100 %/°C temperature coefficient of VBR.
Designed for single-pulse suppression per JEDEC standards, it sustains 5000 W peak power at 25 °C with 0.01 % duty cycle, derates linearly above TA = 25 °C, and handles 600 A non-repetitive forward surge (8.3 ms half-sine). The matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous reverse operating voltage before leakage exceeds 2 µA; defines safe DC working margin. |
| VBR @ IT = 50 mA | 24.4–26.9 V - Breakdown onset range; ensures reliable triggering above nominal rail voltage. |
| VC @ IPPM = 141 A | 35.5 V - Clamped voltage under full 5000 W surge; limits downstream IC stress to safe levels. |
| PPPM | 5000 W - Peak pulse power rating (10/1000 µs); supports IEC 61000-4-5 Level 4 surge immunity. |
| TJ max. | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| Polarity | Unidirectional - Cathode-banded configuration; protects against positive transients only (not AC or bidirectional surges). |

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-E3/52 | Lower PPPM (600 W), smaller SMB package, same VWM = 22 V, higher VC = 35.5 V at 17.1 A. | Suitable for space-constrained consumer PCBs but insufficient for automotive load dump or industrial motor drive surges. | Select when board area is limited and surge energy is ≤600 W (e.g., USB port protection). |
| 1.5KE22A | Same VWM = 22 V and VC = 35.5 V, but lower PPPM = 1500 W and TO-204AA (DO-4) package; no AEC-Q101 qualification. | Lacks automotive qualification and cannot sustain repeated 5000 W surges; used in legacy industrial equipment. | Select only for cost-sensitive, non-automotive applications with verified lower surge exposure. |
Compared with SMBJ22A-E3/52 and 1.5KE22A, the 5KP22HE3/54 delivers 3.3× and 3.3× higher peak power handling respectively, maintains identical clamping performance at higher current, and provides AEC-Q101 assurance - making it the sole choice for automotive and high-reliability industrial designs requiring sustained 5 kW surge immunity.

FAQ
What is the clamping voltage of the 5KP22HE3/54 under maximum surge conditions?
The 5KP22HE3/54 clamps to a maximum of 35.5 V when subjected to its rated peak pulse current of 141 A (10/1000 µs waveform). This value is guaranteed per JEDEC test conditions and represents the upper limit of voltage seen by downstream circuitry during a full 5000 W transient event. The 5KP22HE3/54 maintains this clamping performance across its qualified temperature range of -55 °C to +175 °C.
Is the 5KP22HE3/54 suitable for bidirectional transient protection?
No, the 5KP22HE3/54 is a unidirectional TVS diode and protects only against positive-going transients on the cathode terminal relative to anode. It does not suppress negative voltage excursions or AC surges. For bidirectional protection, two 5KP22HE3/54 devices must be connected in series opposition, or a dedicated bidirectional part such as 5KP22CA should be selected instead.
Does the 5KP22HE3/54 require a heatsink for normal operation?
No heatsink is required for transient suppression duty, as the 5KP22HE3/54 is rated for 5000 W only in short-duration pulses (≤1 ms) with 0.01 % duty cycle. However, for continuous power dissipation, its 8.0 W rating at TL = 75 °C means sustained DC leakage or frequent surges may necessitate thermal management - verify junction temperature rise using the thermal resistance data in Figure 5 of the 88308 datasheet for the 5KP22HE3/54.
How does the AEC-Q101 qualification of the 5KP22HE3/54 impact its use in automotive designs?
The AEC-Q101 qualification of the 5KP22HE3/54 confirms it has passed accelerated stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for automotive powertrain, chassis, and body electronics. This certification eliminates the need for additional qualification testing by Tier 1 suppliers and supports PPAP compliance for the 5KP22HE3/54 in vehicle-level applications.
What is the meaning of the 'HE3' suffix in 5KP22HE3/54?
'HE3' denotes the AEC-Q101 qualified, RoHS-compliant version of the 5KP22A device, with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. The '/54' indicates packaging in 13-inch paper tape and reel, 800 units per reel. This distinguishes it from the commercial-grade 'E3' variant (e.g., 5KP22A-E3/54), which lacks automotive qualification despite identical electrical specs.
