Product details
Overview
5KP75HE3/54 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 5000 W peak pulse power (10/1000 μs), 75 V stand-off voltage (VWM), 83.3–92.1 V breakdown voltage (VBR at 5.0 mA), and clamps to ≤121 V at 41.3 A peak pulse current - used in automotive power supply outputs and industrial sensor interfaces.
For engineers reviewing the 5KP75HE3/54 datasheet, 5KP75HE3/54 pinout, 5KP75HE3/54 application, or 5KP75HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, uni-directional polarity with cathode band marking, and compatibility with 13" paper tape & reel delivery (package code 54).
Technical Context
This TVS diode employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective clamping during inductive switching transients and lightning-induced surges. Its 5000 W peak pulse rating is defined per JEDEC-standard 10/1000 μs waveform with 0.01% duty cycle.
The device operates within -55 °C to +175 °C junction temperature range and supports 600 A non-repetitive forward surge current (8.3 ms half-sine). Its 5.0 μA max reverse leakage at 75 V ensures minimal standby power loss in protected circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 75 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail protection threshold. |
| VBR (min/max) | 83.3 V / 92.1 V at 5.0 mA - Confirmed breakdown range ensuring predictable turn-on under overvoltage conditions. |
| VC @ IPPM | ≤121 V at 41.3 A - Clamping voltage limits downstream IC stress during 5000 W transient events. |
| PPPM | 5000 W - Peak pulse power handling capability per 10/1000 μs waveform; enables robust protection against ISO 7637-2 Pulse 5a/b. |
| TJ max | +175 °C - High-temperature operation supports under-hood automotive and industrial environments. |
| Polarity | Uni-directional - Cathode-marked device intended for DC line protection with polarity-sensitive placement. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |

Applications
| Automotive Power Supply Output Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Uni-directional TVS placed between power rail and ground to clamp surges before they reach LDOs or microcontrollers. Use Value: Withstands 5000 W pulses while limiting clamped voltage to ≤121 V, preserving downstream 3.3 V/5 V logic integrity. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loops) in factory automation sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: Fast-response TVS shunting transients directly at connector interface to prevent op-amp input damage. Use Value: Sub-1 ns response time and 5.0 μA leakage ensure signal fidelity and low-power operation in precision measurement systems. |
| Telecom DC Power Feeds | Switching Power Supply Output Clamping |
Use Scenario: Safeguarding PoE-powered devices (e.g., IP cameras) against induced surges on 48 V DC feed lines. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing common-mode surges on isolated DC inputs without affecting regulation. Use Value: 75 V VWM aligns with IEEE 802.3af/at margin requirements; 121 V clamping prevents overvoltage shutdown of PD controllers. |
Use Scenario: Replacing crowbar circuits in 75 V-output SMPS for telecom rectifiers and server PSUs. IC Role / Device Role / Timing Role: Voltage-clamping element that diverts fault energy while allowing fuse interruption instead of permanent short. Use Value: Enables resettable protection architecture - user replaces fuse and resumes operation after transient clearance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A-E3/52 | Lower peak power (600 W), smaller SMB package, same 75 V VWM, but not AEC-Q101 qualified. | Suitable for space-constrained consumer or industrial PCBs where automotive qualification is unnecessary. | Select when board area is critical and 5000 W surge immunity is not required. |
| 1.5KE75A | Same 75 V VWM | Legacy DO-201 package; higher thermal resistance than P600; no AEC-Q101 qualification. | Choose only for legacy design refreshes where P600 footprint change is not feasible. |
Compared with SMBJ75A-E3/52 and 1.5KE75A, the 5KP75HE3/54 delivers 8.3× higher peak power handling and automotive-grade reliability in a thermally superior P600 package - essential for protecting safety-critical power rails where sustained surge energy must be absorbed without failure.

FAQ
What is the clamping voltage of the 5KP75HE3/54 under maximum surge conditions?
The 5KP75HE3/54 clamps to a maximum of 121 V when subjected to its rated peak pulse current of 41.3 A (10/1000 μs waveform). This value is measured per JEDEC standards and ensures downstream components see limited overvoltage stress during transient events. The 5KP75HE3/54 maintains this clamping performance across its specified operating temperature range.
Is the 5KP75HE3/54 suitable for automotive applications?
Yes, the 5KP75HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, robust P600 package, and validation against thermal cycling and humidity stress make it appropriate for engine control units, body electronics, and ADAS power supplies. The HE3 suffix confirms its automotive-grade qualification status.
How does the 5KP75HE3/54 differ from the standard 5KP75A-E3/54 variant?
The 5KP75HE3/54 differs from the 5KP75A-E3/54 solely in qualification level: the "H" denotes AEC-Q101 qualification, while the base version is commercial-grade. Both share identical electrical parameters (VWM = 75 V, VBR = 83.3–92.1 V, VC ≤ 121 V), P600 package, and RoHS compliance. The HE3 variant undergoes additional automotive reliability testing per JESD22 and JESD201 standards.
What is the reverse leakage current specification for the 5KP75HE3/54 at rated standoff voltage?
The 5KP75HE3/54 exhibits a maximum reverse leakage current of 5.0 μA at its 75 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power loss in always-on systems such as telematics modules and sensor nodes, supporting extended battery life and thermal efficiency in protected circuits.
Can the 5KP75HE3/54 be used in bidirectional configurations?
No, the 5KP75HE3/54 is strictly unidirectional, as confirmed by Vishay's datasheet and polarity marking (cathode band). It conducts only when reverse-biased beyond VBR; forward conduction occurs above ~3.5 V. For AC or bidirectional transient protection, a dedicated bidirectional TVS (e.g., 5KP75CA) or back-to-back unidirectional pair is required - the 5KP75HE3/54 alone cannot suppress positive-going transients on grounded lines.
