Product details
Overview
5KP10HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, rated for 5000 W peak pulse power (10/1000 μs), 10.0 V stand-off voltage (VWM), and 17.0 V clamping voltage (VC) at 294 A peak pulse current. It provides robust overvoltage protection for DC power rails in automotive ECUs and industrial motor drives.
For engineers reviewing the 5KP10HE3/54 datasheet, 5KP10HE3/54 pinout, 5KP10HE3/54 application, or 5KP10HE3/54 equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, low incremental surge resistance, and RoHS-compliant matte tin-plated leads suitable for high-reliability 8.3 ms surge events and repetitive transients.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 11.1–12.3 V breakdown range (VBR at 50 mA). Its P600 glass-passivated junction enables fast response (<1 ns) and stable clamping under 10/1000 μs surges up to 5000 W.
Designed for primary-side DC rail protection, it sustains 600 A non-repetitive forward surge (8.3 ms half-sine) and maintains operation from –55 °C to +175 °C junction temperature, with thermal derating above 25 °C ambient per Fig. 2 and Fig. 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - Maximum continuous reverse operating voltage before conduction begins; sets safe DC rail margin. |
| VBR (min/max) | 11.1 V / 12.3 V at 50 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC @ IPPM | 17.0 V at 294 A - Clamped voltage during 5000 W surge; limits downstream IC stress below 18 V. |
| PPPM | 5000 W - Peak pulse power handling (10/1000 μs); supports high-energy lightning or inductive switch-off events. |
| IFSM | 600 A - Non-repetitive forward surge rating (8.3 ms); withstands fuse-clearing or breaker-trip duration surges. |
| TJ max | +175 °C - Maximum junction temperature; enables use in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive electronics reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; polarity indicated by cathode band; UL 94 V-0 compliant; RoHS and JESD 201 Class 2 whisker tested (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to system ground or low-side reference; carries full surge current during clamping. |
| Cathode | Protected line connection | Connected to DC rail (e.g., 12 V battery line); voltage referenced to anode during transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 surges without parallel staging. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain and body control modules requiring extended temperature and lifetime validation. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage overshoot during fast transients, protecting 12 V-rated MOSFETs and microcontrollers. |
| 175 °C maximum junction temperature | Supports placement near heat-generating components (e.g., DC-DC converters) without thermal derating penalties. |
| Matte tin plating (JESD 22-B102 compliant) | Ensures reliable solder wetting and intermetallic formation in lead-free reflow profiles up to 260 °C peak. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10AHE3/52 | Lower peak power (600 W), SMC package, same VWM (10 V), higher VC (17.0 V @ 34.6 A) | Suitable for lower-energy transients (IEC 61000-4-2 ESD only); not rated for load dump or IEC 61000-4-5. | Select when space-constrained layouts require SMC footprint and surge energy remains below 100 J. |
| 1.5KE10A | Same VWM (10 V) and VC (17.0 V), but lower PPPM (1500 W), DO-201 package, no AEC-Q101 qualification | Lacks automotive qualification and thermal robustness; limited to commercial-grade power supplies. | Choose for cost-sensitive consumer designs where AEC-Q101 and 5000 W capability are unnecessary. |
Compared with SMBJ10AHE3/52 and 1.5KE10A, the 5KP10HE3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, retains AEC-Q101 validation, and supports direct replacement in high-energy automotive and industrial rail protection without layout revision.

FAQ
What is the clamping voltage of the 5KP10HE3/54 under maximum surge conditions?
The 5KP10HE3/54 clamps to 17.0 V at its rated peak pulse current of 294 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and guarantees consistent overvoltage limiting during standardized surge events, directly protecting downstream 12 V logic and power ICs.
Is the 5KP10HE3/54 suitable for automotive applications?
Yes, the 5KP10HE3/54 carries AEC-Q101 qualification and is explicitly rated for automotive use. Its 175 °C maximum junction temperature, robust P600 package, and validated performance under load dump and ISO 7637-2 transients make it appropriate for engine control units, body controllers, and ADAS power domains.
What does the "HE3" suffix indicate in 5KP10HE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this grade from commercial-only "E3" variants and confirms compliance with automotive reliability standards for tin-plated terminations and thermal cycling endurance.
How does the 5KP10HE3/54 differ from the standard 5KP10A?
The 5KP10HE3/54 is identical in electrical specifications to 5KP10A but adds AEC-Q101 qualification, Class 2 whisker resistance, and RoHS compliance. The "HE3" version is intended for automotive and high-reliability industrial use, whereas 5KP10A lacks formal automotive validation and may use non-whisker-resistant plating.
Can the 5KP10HE3/54 be used in bidirectional configurations?
No, the 5KP10HE3/54 is unidirectional only, with cathode marked by a color band. For bidirectional transient suppression, Vishay offers separate dual-diode configurations such as the 5KP10CA series; using two 5KP10HE3/54 devices in series-opposed is not recommended due to mismatched VBR tolerances and undefined forward conduction behavior.
