Product details
Overview
5KP6.5AHE3/73 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 5000 W peak pulse power (10/1000 μs), 6.5 V stand-off voltage, 7.22–7.98 V breakdown voltage at 50 mA, and clamps to ≤11.2 V at 446 A peak pulse current. It is AEC-Q101 qualified and used in automotive power supply overvoltage protection.
For engineers reviewing the 5KP6.5AHE3/73 datasheet, 5KP6.5AHE3/73 pinout, 5KP6.5AHE3/73 application, or 5KP6.5AHE3/73 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under standardized transients, RoHS and whisker-test compliance (JESD 201 Class 2), and direct alternatives for automotive-grade TVS selection.
Technical Context
The 5KP6.5AHE3/73 employs a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables use in DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
It operates across –55 °C to +175 °C junction temperature, with power dissipation derated linearly above 25 °C ambient and validated for repetitive 0.01% duty cycle surges. Clamping voltage (VC = 11.2 V @ IPPM) and breakdown tolerance (±5%) are specified per JEDEC registered test conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5AHE3/52 | Lower peak power (600 W), smaller SMB package, same VWM/VBR range | Not suitable for load dump; limited to ESD and low-energy transients | Select when space-constrained and surge energy ≤600 W |
| 1.5KE6.8A | Same P600 package, 1500 W rating, slightly higher VBR (7.14–7.88 V), no AEC-Q101 | Lacks automotive qualification; requires revalidation for under-hood use | Select for cost-sensitive industrial designs without automotive requirements |
Compared with SMBJ6.5AHE3/52 and 1.5KE6.8A, the 5KP6.5AHE3/73 uniquely delivers 5000 W clamping with AEC-Q101 validation in P600-making it the only choice for automotive load-dump immunity where both energy capacity and qualification are mandatory.

FAQ
What is the maximum clamping voltage of the 5KP6.5AHE3/73 under peak surge conditions?
The 5KP6.5AHE3/73 clamps to a maximum of 11.2 V when subjected to its rated peak pulse current of 446 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and guarantees consistent overvoltage limiting during standardized transients such as ISO 7637-2 Pulse 5a. The clamping voltage directly determines the stress imposed on downstream components like voltage regulators and interface ICs.
Is the 5KP6.5AHE3/73 suitable for bidirectional transient protection?
No, the 5KP6.5AHE3/73 is unidirectional only, as confirmed in the Vishay datasheet. It conducts in reverse bias above VBR but blocks forward current beyond ~3.5 V. For AC or bidirectional signal line protection, a dual-diode configuration or a dedicated bidirectional TVS (e.g., 5KP6.5CA) must be used instead of the 5KP6.5AHE3/73.
Does the HE3 suffix on 5KP6.5AHE3/73 indicate AEC-Q101 qualification?
Yes-the HE3 suffix explicitly denotes RoHS-compliant construction with AEC-Q101 qualification, as stated in the Vishay mechanical data section. This distinguishes it from the E3 suffix (commercial grade only). The 5KP6.5AHE3/73 has undergone full AEC-Q101 stress testing including HTGB, H3TRB, and surge endurance, making it suitable for automotive under-hood applications.
What is the thermal derating behavior of the 5KP6.5AHE3/73 above 25 °C ambient?
The 5KP6.5AHE3/73 follows a linear derating curve: its peak pulse power remains at 5000 W up to TJ = 25 °C, then decreases proportionally as junction temperature rises, reaching zero at +175 °C. Derating is defined in Figure 2 of the datasheet and applies to both single-pulse and repetitive 0.01% duty cycle operation. PCB copper area and lead length significantly impact achievable TJ.
Can the 5KP6.5AHE3/73 replace a 5KP6.0AHE3/73 in an existing design?
Yes-both share identical P600 package, AEC-Q101 qualification, and thermal/mechanical specifications. The 5KP6.5AHE3/73 offers a higher VWM (6.5 V vs. 6.0 V) and slightly elevated VBR (7.22–7.98 V vs. 6.67–7.37 V), providing improved noise immunity while maintaining compatible clamping performance (VC = 11.2 V vs. 10.3 V). No layout or reliability revalidation is required if the higher standoff voltage aligns with system requirements.
