Product details
Overview
5KP7.5AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping on DC power rails and signal lines. It features 7.5 V stand-off voltage (VWM), 8.33–9.21 V breakdown voltage (VBR) at 5.0 mA, 12.9 V maximum clamping voltage (VC) at 388 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used to protect MOSFETs and ICs against inductive switching transients in automotive power supplies.
For engineers reviewing the 5KP7.5AHE3/54 datasheet, 5KP7.5AHE3/54 pinout, 5KP7.5AHE3/54 application, or 5KP7.5AHE3/54 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under 10/1000 μs surges, RoHS/AEC-Q101 compliance status, and direct alternatives with documented VC, VBR, and IPPM differences - all critical for overvoltage protection design validation and automotive BOM qualification.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its VBR range (8.33–9.21 V). Its P600 glass-passivated junction enables low incremental surge resistance and sub-nanosecond response time, ensuring fast suppression of ESD and load-dump transients before downstream components are damaged.
It is rated for 5000 W peak pulse power (10/1000 μs), 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and withstands 600 A non-repetitive forward surge (8.3 ms half-sine). Junction temperature range is –55 °C to +175 °C, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.5 V - Maximum continuous reverse operating voltage; defines safe DC rail margin before clamping begins. |
| VBR (min/max) | 8.33 V / 9.21 V at 5.0 mA - Breakdown threshold range; determines earliest clamping onset under surge conditions. |
| VC @ IPPM | 12.9 V at 388 A - Clamped voltage during full-rated 5000 W transient; sets worst-case overvoltage seen by protected IC. |
| PPPM | 5000 W (10/1000 μs) - Peak surge energy handling capacity; validates suitability for ISO 7637-2 Pulse 5a load-dump events. |
| ID @ VWM | 250 μA max - Reverse leakage at stand-off; ensures minimal quiescent power loss in always-on protection circuits. |
| TJ max. | +175 °C - Maximum junction temperature; supports placement near hot power stages without thermal shutdown risk. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD47. |
Pinout & Package
P600 package: axial-leaded, molded epoxy body with cathode band marking; meets UL 94 V-0 flammability; matte tin-plated leads solderable per J-STD-002; RoHS compliant (HE3 suffix = AEC-Q101 qualified).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional clamp configuration. |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); conducts avalanche current when Vreverse > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against severe automotive load-dump transients without series impedance or crowbar circuitry. |
| AEC-Q101 qualification | Confirms robustness across temperature cycling, high-temp reverse bias, and mechanical shock - required for engine control unit (ECU) front-end protection. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage overshoot during clamping, reducing stress on downstream 12 V-rated MOSFETs and regulators. |
| P600 glass-passivated junction | Delivers stable VBR tolerance and low dynamic impedance (< 0.03 Ω typical), ensuring repeatable clamping performance over lifetime. |
| 175 °C max junction temperature | Permits direct mounting on high-temperature PCB zones (e.g., near DC/DC converters) without thermal derating penalties. |
Applications
| Automotive Power Rail Protection | Industrial DC Power Supply Clamp |

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 SMAJ7.5A | Lower PPPM (400 W), smaller SMA package, VBR = 8.3–9.17 V, VC = 12.0 V @ 33.3 A | Suitable for low-energy signal-line protection; insufficient for automotive load-dump duty. | Select 5KP7.5AHE3/54 when 5000 W surge rating and AEC-Q101 qualification are mandatory. |
| ON Semiconductor 1.5KE7.5A | Same P600 package, 1500 W PPPM, VBR = 8.33–9.21 V, VC = 12.0 V @ 125 A, no AEC-Q101 listing | Valid for industrial power supply clamping but not certified for automotive under-hood use. | Choose 5KP7.5AHE3/54 where automotive qualification and 3.3× higher surge capacity are required. |
Compared with SMAJ7.5A and 1.5KE7.5A, the 5KP7.5AHE3/54 delivers 3.3× and 12.5× higher peak pulse power respectively, maintains identical VBR tolerance, and is the only one AEC-Q101 qualified - making it the sole choice for automotive load-dump protection where reliability and energy handling are non-negotiable.

FAQ
What is the clamping voltage of the 5KP7.5AHE3/54 under full-rated surge current?
The 5KP7.5AHE3/54 has a maximum clamping voltage (VC) of 12.9 V when subjected to its rated peak pulse current of 388 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and guarantees the protected circuit will not experience more than 12.9 V during a 5000 W transient event. The low VC/VBR ratio (~1.44) reflects high clamping efficiency essential for safeguarding 12 V logic and power ICs.
Is the 5KP7.5AHE3/54 suitable for automotive applications?
Yes, the 5KP7.5AHE3/54 is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and infotainment power rails. Its –55 °C to +175 °C operating range, load-dump surge capability (ISO 7637-2 Pulse 5a), and RoHS-compliant HE3 construction meet stringent OEM requirements. The device appears in Vishay's automotive-grade TransZORB® portfolio with full qualification documentation.
What does the "HE3/54" suffix indicate in 5KP7.5AHE3/54?
The "HE3" suffix denotes RoHS compliance and AEC-Q101 qualification per JESD201 Class 2 whisker testing, while "/54" specifies the preferred packaging: 13-inch paper tape and reel containing 800 units. This ordering code ensures traceability to Vishay's qualified manufacturing lot and confirms adherence to automotive reliability standards - distinct from commercial-grade "E3" variants lacking AEC-Q101 validation.
How does the 5KP7.5AHE3/54 compare to standard Zener diodes in surge protection?
Unlike standard Zener diodes, the 5KP7.5AHE3/54 is optimized for high-energy transient suppression: it handles 5000 W (vs. typically <5 W for Zeners), exhibits faster response (<1 ns vs. ~10–100 ns), and maintains stable clamping under repetitive surges. Its P600 package provides superior thermal mass and surge current capability, whereas Zeners lack defined peak pulse ratings and degrade rapidly under similar stress - making the 5KP7.5AHE3/54 the appropriate choice for system-level ESD and load-dump protection.
Can the 5KP7.5AHE3/54 be used in bidirectional configurations?
No, the 5KP7.5AHE3/54 is unidirectional only, as confirmed in Vishay's datasheet features section. It conducts in reverse avalanche mode above VBR but blocks forward current like a standard diode. For bidirectional protection (e.g., AC lines or differential data buses), a separate symmetric TVS array or dual-series configuration would be required - the 5KP7.5AHE3/54 itself must be oriented with cathode toward the protected line and anode to reference ground or low-side rail.
