Product details
Overview
5KP54HE3/73 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 54 V stand-off voltage (VWM), 60–66.3 V breakdown voltage (VBR), 5000 W peak pulse power (10/1000 µs), 57.4 A peak pulse current (IPPM), and clamps to ≤87.1 V at rated surge - used in automotive power supply outputs and industrial sensor interfaces.
For engineers reviewing the 5KP54HE3/73 datasheet, 5KP54HE3/73 pinout, 5KP54HE3/73 application, or 5KP54HE3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, clamping performance under standardized transients, and direct replacement guidance for high-reliability overvoltage protection design.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds its VBR threshold. Its P600 glass-passivated junction enables robust 5000 W surge handling with low incremental surge resistance and sub-nanosecond response time.
Rated for -55 °C to +175 °C junction temperature, it supports AEC-Q101 qualified automotive applications and complies with JESD 22-B106 soldering (275 °C, 10 s). The HE3 suffix confirms RoHS compliance and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54 V - Maximum continuous reverse operating voltage before leakage exceeds 2 µA; defines safe DC bias margin. |
| VBR @ IT = 50 mA | 60.0–66.3 V - Breakdown voltage range confirming reliable avalanche initiation at defined test current. |
| VC @ IPPM | ≤87.1 V - Clamped voltage during 57.4 A 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPM | 5000 W - Peak pulse power rating per JEDEC-standard 10/1000 µs waveform; defines single-event surge capacity. |
| IPPM | 57.4 A - Peak pulse current corresponding to 5000 W at VC; used for PCB trace and fuse sizing. |

Pinout & Package
5KP54HE3/73 uses the axial-lead P600 package (JEDEC DO-201AD), with cathode indicated by a color band. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and rated for 275 °C / 10 s solder dip.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side connection | Connected to ground or lower-potential rail in unidirectional clamp configuration. |
| Cathode | Reverse-biased terminal / high-side connection | Connected to protected line (e.g., 54 V rail); color band identifies this end. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 µs) | Enables protection against severe ISO 7637-2 Pulse 5a/b surges without crowbar circuits. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain and body electronics requiring extended lifetime under thermal stress. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage exposure to downstream MOSFETs or microcontrollers during transients. |
| P600 glass-passivated junction | Provides stable VBR tolerance and long-term reliability vs. polymer-based TVS alternatives. |
| JESD 201 Class 2 whisker resistance | Ensures lead integrity in high-humidity, high-temperature environments without tin whisker growth risk. |
Applications
| Automotive Power Supply Output Protection | Industrial Sensor Signal Line Clamp |
|---|---|
Use Scenario: Protecting 54 V battery-fed ECUs from load dump and alternator switching transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input rail to clamp surges before they reach DC/DC converters and MCU power inputs. Use Value: Limits transient voltage to ≤87.1 V during 57.4 A events, preventing latch-up or gate oxide damage in downstream silicon. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and inductive kickback in factory automation systems. IC Role / Device Role / Timing Role: Parallel-connected TVS on 24–60 V sensor bus lines to absorb fast-rising transients before reaching ADC front-end or isolation amplifiers. Use Value: Sub-1 ns response ensures clamping occurs before sensitive analog circuitry experiences destructive overvoltage. |
| Telecom DC Feeder Surge Suppression | Switched-Mode Power Supply Output Crowbar Replacement |
Use Scenario: Safeguarding remote radio unit (RRU) power feeds exposed to lightning-induced surges on outdoor telecom infrastructure. IC Role / Device Role / Timing Role: Primary overvoltage protector on +48 V DC feeder lines, coordinated with upstream GDTs and downstream fuses. Use Value: 5000 W rating handles multi-kA induced surges while maintaining low leakage (<2 µA at 54 V) during normal operation. |
Use Scenario: Replacing SCR-based crowbar circuits in 54 V output SMPS to avoid latching failure and enable automatic recovery after overvoltage. IC Role / Device Role / Timing Role: Self-resetting shunt protector that clamps but does not short-circuit, allowing system reset without manual intervention. Use Value: Enables fault-tolerant power delivery where fuse replacement or breaker reset would cause downtime in critical systems. |
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 SMAJ54A | DO-214AC (SMA) package, 400 W PPPM, 54 V VWM, 87.1 V VC - lower surge capacity, surface-mount only. | Suitable for space-constrained PCBs but insufficient for ISO 7637-2 Pulse 5; limited to IEC 61000-4-5 Level 3. | Select when board area is critical and surge energy is ≤400 W; not drop-in for 5KP54HE3/73's P600 footprint or automotive load-dump duty. |
| ON Semiconductor 1.5KE56A | DO-201AE package, 1500 W PPPM, 56 V VWM, 93.6 V VC - lower power rating, higher clamping voltage. | Acceptable for consumer-grade power supplies but fails AEC-Q101; not validated for automotive under-hood use. | Choose for cost-sensitive industrial designs where 1500 W surge immunity suffices and automotive qualification is unnecessary. |
Compared with SMAJ54A and 1.5KE56A, the 5KP54HE3/73 delivers 3.3× higher surge power handling, AEC-Q101 validation for automotive deployment, and tighter clamping - making it the sole option among the three qualified for load-dump protection in engine control modules.

FAQ
What is the clamping voltage of the 5KP54HE3/73 under full-rated surge conditions?
The 5KP54HE3/73 clamps to a maximum of 87.1 V when subjected to its rated 57.4 A peak pulse current (IPPM) 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 worst-case transients. Designers must ensure downstream components tolerate this clamped level.
Is the 5KP54HE3/73 suitable for bidirectional transient protection?
No, the 5KP54HE3/73 is a unidirectional TVS diode, intended only for DC circuits with defined polarity. It conducts in reverse avalanche above VBR but blocks forward current like a standard diode. For AC or bipolar signal lines, a bidirectional variant such as 5KP54CA or separate back-to-back unidirectional devices are required - the 5KP54HE3/73 itself provides no forward surge suppression capability.
Does the HE3 suffix on 5KP54HE3/73 indicate AEC-Q101 qualification?
Yes, the HE3 suffix explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - confirming suitability for automotive powertrain and chassis applications. The base E3 suffix indicates RoHS compliance only; HE3 adds automotive reliability validation.
What is the maximum allowable mounting temperature for soldering the 5KP54HE3/73?
The 5KP54HE3/73 leads are rated for solder dip at 275 °C maximum for 10 seconds per JESD 22-B106. Reflow profiles must stay within this thermal limit to avoid junction degradation or epoxy molding compound delamination. Lead finish is matte tin, compatible with J-STD-002 and JESD 22-B102 solderability standards.
How does the 5KP54HE3/73 compare to smaller-package TVS diodes like SMAJ54A in surge handling?
The 5KP54HE3/73 delivers 5000 W peak pulse power in the P600 package, whereas SMAJ54A (DO-214AC) is rated for only 400 W. This 12.5× higher energy capacity allows the 5KP54HE3/73 to survive automotive load dump events (ISO 7637-2 Pulse 5) that would destroy SMAJ54A. Physical size and thermal mass directly enable this performance difference.
