Product details
Overview
5KP48HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features 48 V stand-off voltage (VWM), 53.3–58.9 V breakdown voltage (VBR), 77.4 V maximum clamping voltage at 64.6 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the 5KP48HE3/54 datasheet, 5KP48HE3/54 pinout, 5KP48HE3/54 application, or 5KP48HE3/54 equivalent, this device is selected for automotive-grade overvoltage protection where AEC-Q101 qualification, low clamping ratio, and robust 175 °C junction temperature capability are required in switching power supply outputs and sensor interface circuits.
Technical Context
The 5KP48HE3/54 operates as a silicon avalanche diode with glass-passivated P600 junction, optimized for fast response (<1 ns) to transient events such as inductive load switching and ESD. Its unidirectional polarity enables integration into DC-biased lines without reverse conduction concerns.
It delivers 5000 W peak pulse power handling under JEDEC-standard 10/1000 µs waveform at 0.01% duty cycle, with thermal derating above 25 °C ambient per Fig. 2 and power dissipation limited to 8.0 W on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 48.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin. |
| VBR (min/max) | 53.3 V / 58.9 V - Breakdown occurs within this range at 50 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 77.4 V - Clamped voltage at 64.6 A peak pulse current; determines protected circuit's maximum transient stress. |
| PPPM | 5000 W - Peak pulse power capability with 10/1000 µs waveform; supports high-energy surge immunity per IEC 61000-4-5. |
| TJ max. | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronics reliability including temperature cycling and HTRB. |
| Package | P600 - Axial-leaded, molded epoxy case with UL 94 V-0 rating; compatible with wave soldering (275 °C, 10 s max). |
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 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during positive transients when used in reverse-biased configuration. |
| Cathode | Clamping terminal | Marked by color band; connected to higher-potential side (e.g., VCC rail); avalanche conduction initiates here during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring long-term reliability under thermal cycling and humidity. |
| 5000 W peak pulse power | Withstands severe surges such as ISO 7637-2 Pulse 5a (load dump) without degradation, enabling single-device protection without parallel staging. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes voltage overshoot across protected ICs like MCUs or CAN transceivers, reducing risk of latch-up or gate oxide damage. |
| 175 °C max junction temperature | Supports placement near heat-generating components (e.g., power MOSFETs) in compact power supply designs without thermal derating penalties. |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance-critical for high-reliability industrial and automotive PCB assemblies. |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 48 V battery-fed ECUs against load dump transients up to 120 V and 500 ms duration. IC Role / Device Role / Timing Role: Primary clamping element placed between VBAT and ground, conducting only during overvoltage events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ48AHE3/52 | Lower peak power (600 W), smaller SMB package, same 48 V VWM and AEC-Q101 qualification. | Suitable for space-constrained PCBs with lower surge exposure (e.g., infotainment USB ports), not for load dump. | Select 5KP48HE3/54 when >1 kW surge energy must be absorbed; choose SMBJ48AHE3/52 for board area savings in non-critical zones. |
| 1.5KE48A | Same VWM and VBR range but lower PPPM (1500 W), TO-204AA (DO-4) package, no AEC-Q101 qualification. | Limited to commercial/industrial use; lacks automotive reliability validation and thermal robustness. | Use 5KP48HE3/54 for automotive or harsh-environment designs; 1.5KE48A remains viable for cost-sensitive consumer power supplies. |
Compared with SMBJ48AHE3/52 and 1.5KE48A, the 5KP48HE3/54 provides triple the peak power handling and automotive-grade qualification-making it the sole choice for protecting 48 V systems exposed to ISO 7637-2 load dump or IEC 61000-4-5 surges exceeding 3 kV.

FAQ
What is the clamping voltage of the 5KP48HE3/54 under maximum rated surge current?
The 5KP48HE3/54 exhibits a maximum clamping voltage (VC) of 77.4 V when subjected to its rated peak pulse current (IPPM) of 64.6 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The 5KP48HE3/54 maintains this clamping performance across its qualified operating temperature range.
Is the 5KP48HE3/54 suitable for automotive applications?
Yes, the 5KP48HE3/54 carries full AEC-Q101 qualification, confirming compliance with stress tests for temperature cycling, high-temperature reverse bias, and humidity resistance required in automotive electronics. Its 175 °C maximum junction temperature and P600 package robustness make it appropriate for under-hood ECUs, body control modules, and ADAS sensor power rails. The HE3 suffix explicitly denotes this automotive qualification.
How does the 5KP48HE3/54 differ from the 5KP48A-E3/54 variant?
The 5KP48HE3/54 differs from 5KP48A-E3/54 solely in qualification level: the "H" in HE3 indicates AEC-Q101 qualification, whereas the "E3" suffix alone denotes RoHS-compliant commercial grade. Both share identical electrical parameters (VWM = 48 V, VBR = 53.3–58.9 V, VC = 77.4 V), P600 package, and thermal ratings-but only the 5KP48HE3/54 is approved for automotive use per the Vishay datasheet revision 20-Nov-12.
What is the maximum peak pulse current the 5KP48HE3/54 can handle?
The 5KP48HE3/54 is rated for a maximum peak pulse current (IPPM) of 64.6 A under the standardized 10/1000 µs double-exponential waveform. This value is derived directly from its 5000 W peak pulse power rating and 77.4 V clamping voltage (IPPM = PPPM / VC). Derating applies above 25 °C ambient per Figure 2 in the Vishay datasheet 88308.
Does the 5KP48HE3/54 have bidirectional polarity?
No, the 5KP48HE3/54 is strictly unidirectional, as confirmed in the Vishay datasheet section "FEATURES" and "PRIMARY CHARACTERISTICS". It functions as a reverse-biased avalanche diode-conducting only when cathode voltage exceeds anode voltage by ≥VBR-and cannot suppress positive transients on grounded lines without external biasing. For bidirectional protection, separate devices or dedicated bidirectional TVS arrays are required.
