Product details
Overview
5KP15AHE3_A/C from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on power rails and signal lines. It features 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 5 mA, 5000 W peak pulse power (10/1000 μs), 24.4 V clamping voltage at 205 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the 5KP15AHE3_A/C datasheet, 5KP15AHE3_A/C pinout, 5KP15AHE3_A/C application, or 5KP15AHE3_A/C equivalent, key selection criteria include clamping performance under 10/1000 μs surges, unidirectional polarity compatibility with DC-biased rails, thermal derating above 25 °C, and P600 leaded package mounting requirements for high-surge-current PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during transients-triggering when reverse voltage exceeds VBR and limiting downstream voltage to ≤24.4 V at 205 A. Its P600 glass-passivated junction enables robust 5000 W surge handling with low incremental surge resistance and sub-nanosecond response time.
Designed for DC power line protection, it sustains 8.0 W steady-state dissipation on an infinite heatsink at TL = 75 °C and withstands 500 A non-repetitive forward surge (8.3 ms half-sine). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.0 V - Maximum continuous reverse operating voltage before leakage exceeds 2.0 μA; defines safe DC bias margin. |
| VBR min/max | 16.7 V / 18.5 V at 5 mA - Tight breakdown window ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 24.4 V at 205 A - Clamping voltage under full 10/1000 μs surge; determines maximum stress on protected IC or MOSFET. |
| PPPM | 5000 W - Peak pulse power rating per JEDEC standard; validates suitability for IEC 61000-4-5 Level 4 (4 kV) testing. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| Polarity | Unidirectional - Requires cathode band oriented toward positive rail; not suitable for AC or bidirectional signal lines. |
| Package | P600 - Axial-leaded, UL 94 V-0 molded epoxy case; 9.5 mm body length, 1.32 mm lead diameter; requires ≥10 mm creepage clearance. |
Pinout & Package
P600 package: axial-leaded, matte tin-plated leads, cathode indicated by color band. Leads solderable per J-STD-002 and JESD 22-B102; rated for 275 °C dip soldering (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Cathode terminal | Connected to higher-potential side of protected circuit; clamps when reverse voltage exceeds VBR. |
| Cathode (non-banded end) | Anode terminal | Connected to ground or lower-potential reference; completes current path during surge conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications per stress test requirements including HTGB, TCT, and HTRB. |
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against IEC 61000-4-5 combination wave surges up to 4 kV without cascading devices. |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage overshoot during fast transients, reducing risk of gate oxide damage in downstream MOSFETs. |
| P600 glass-passivated junction | Provides stable VBR over lifetime and improved moisture resistance vs. epoxy-only passivation; meets JESD22-A110 reliability. |
| 175 °C max junction temperature | Supports placement near heat-generating components (e.g., DC-DC converters) without thermal derating penalties. |
Applications

IC Role / Device Role / Timing Role: Installed at DC input connector to shunt common-mode transients into chassis ground before reaching DC-DC isolation stage. Use Value: 24.4 V clamping voltage ensures protected Ethernet PHYs remain within absolute maximum ratings during 10/1000 μs events. |
Use Scenario: Adding secondary overvoltage protection on +5 V or +12 V outputs of consumer-grade AC-DC adapters. IC Role / Device Role / Timing Role: Placed after output capacitor to catch residual spikes escaping primary-side regulation and filtering. Use Value: 15 V VWM allows clean operation under nominal conditions while reacting within nanoseconds to fast-rising transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Lower PPPM (600 W), SMC package, same VWM/VBR range but smaller thermal mass. | Suitable for lower-energy surges (IEC 61000-4-2 ESD only); not rated for IEC 61000-4-5 Level 4. | Select SMBJ15A only if surge energy is ≤600 W and board space constraints prohibit P600 footprint. |
| 1.5KE15A | Same P600 package and 5000 W rating, but legacy series with wider VBR tolerance (16.7–20.2 V) and no AEC-Q101 qualification. | Lacks automotive qualification; higher clamping voltage (25.1 V) reduces system margin. | Choose 1.5KE15A only for cost-sensitive industrial applications where AEC-Q101 is not required and 0.7 V higher VC is acceptable. |
Compared with SMBJ15A and 1.5KE15A, the 5KP15AHE3_A/C delivers tighter VBR control, lower clamping voltage, and certified automotive reliability-making it the preferred choice for safety-critical 12 V/24 V systems requiring repeatable surge immunity.

FAQ
What is the clamping voltage of the 5KP15AHE3_A/C under maximum surge current?
The 5KP15AHE3_A/C clamps to 24.4 V at its rated peak pulse current of 205 A (10/1000 μs waveform). This value is measured per JEDEC standards and represents the maximum voltage seen by downstream components during worst-case surge events. The clamping voltage remains stable across temperature due to the device's low temperature coefficient of VBR (0.094 %/°C).
Is the 5KP15AHE3_A/C suitable for bidirectional signal line protection?
No, the 5KP15AHE3_A/C is unidirectional only, with polarity marked by a cathode band. It conducts only when reverse-biased beyond VBR and cannot suppress positive-going transients on AC or differential signal lines. For bidirectional protection, consider the 5KP15CAHE3_A/C variant or discrete back-to-back TVS configurations.
Does the HE3 suffix on 5KP15AHE3_A/C indicate RoHS compliance and automotive qualification?
Yes-the HE3 suffix denotes both RoHS compliance (per Directive 2011/65/EU) and AEC-Q101 qualification. The "H" signifies AEC-Q101, "E3" confirms RoHS-compliant matte tin plating and JESD 201 Class 2 whisker resistance. This makes the 5KP15AHE3_A/C appropriate for automotive power modules and chassis electronics.
What is the maximum continuous power dissipation for the 5KP15AHE3_A/C?
The 5KP15AHE3_A/C has a steady-state power dissipation rating of 8.0 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. Derating begins above 25 °C ambient, following the curve in Figure 5 of the datasheet-e.g., at TA = 75 °C, PD drops to ~4.5 W. This rating applies only to continuous DC or low-frequency leakage, not transient events.
How does the 5KP15AHE3_A/C compare to the older 1.5KE15A in terms of surge performance?
The 5KP15AHE3_A/C offers superior surge performance versus 1.5KE15A: tighter VBR tolerance (16.7–18.5 V vs. 16.7–20.2 V), lower clamping voltage (24.4 V vs. 25.1 V), and AEC-Q101 qualification. Both share the P600 package and 5000 W rating, but the 5KP15AHE3_A/C provides better design margin and automotive compliance out-of-box.
