Product details
Overview
5KP24HE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 24 V stand-off voltage (VWM), and 38.9 V clamping voltage (VC) at 129 A peak pulse current. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines in automotive power supplies and industrial switching systems.
For engineers reviewing the 5KP24HE3/73 datasheet, 5KP24HE3/73 pinout, 5KP24HE3/73 application, or 5KP24HE3/73 equivalent, key selection criteria include unidirectional polarity, 24 V reverse stand-off rating, 38.9 V clamping performance under 129 A surge, AEC-Q101 qualification for automotive reliability, and P600 through-hole package compatibility with high-power board-level transient suppression.
Technical Context
The 5KP24HE3/73 employs a glass-passivated P600 junction optimized for fast response to transients induced by inductive load switching or lightning surges. Its low incremental surge resistance and excellent clamping capability ensure predictable voltage limiting during 10/1000 μs waveforms up to 5000 W.
Designed for use on switching power supply outputs, it replaces crowbar circuits by sustaining high peak currents long enough to allow fuse interruption or circuit breaker tripping-enabling system reset without component replacement. Thermal management relies on lead temperature derating per Fig. 5, with max junction temperature of 175 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Lower peak power (600 W), SMC package, same VWM (24 V), higher VC (38.9 V → 39.4 V), lower IPPM (32.9 A vs. 129 A) | Targeted at lower-energy surges; unsuitable for load dump or high-current industrial transients | Select 5KP24HE3/73 when >100 A surge current or >3 kW pulse power is required; SMBJ24A fits space-constrained designs with moderate threat levels. |
| 1.5KE24A | Same VWM (24 V), lower PPPM (1500 W), DO-201 package, VC = 36.0 V at 41.7 A | Limited to consumer-grade applications; lacks AEC-Q101 qualification and thermal robustness for automotive use | Choose 5KP24HE3/73 for AEC-Q101 compliance and 5000 W capability; 1.5KE24A may be used only in non-automotive, low-duty-cycle scenarios. |
Compared with SMBJ24A and 1.5KE24A, the 5KP24HE3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, supports 3.9× and 3.1× greater surge current, and is the only AEC-Q101-qualified option-making it the sole choice for automotive load dump and industrial motor drive protection where sustained high-energy clamping is mandatory.

FAQ
What is the clamping voltage of the 5KP24HE3/73 under maximum surge conditions?
The 5KP24HE3/73 clamps to 38.9 V at its rated peak pulse current of 129 A (10/1000 μs waveform). This value is measured per JEDEC standards and represents the maximum voltage imposed on protected circuitry during a full-rated transient event. The clamping voltage remains stable across temperature due to the device's low temperature coefficient of VBR (0.101 %/°C), ensuring consistent protection in automotive and industrial environments where ambient temperatures vary widely. The 5KP24HE3/73 maintains this clamping performance without degradation over its specified lifetime when operated within derated power limits.
Is the 5KP24HE3/73 suitable for automotive under-hood applications?
Yes, the 5KP24HE3/73 is AEC-Q101 qualified and rated for junction temperatures up to 175 °C, making it suitable for under-hood automotive applications such as engine control units, body control modules, and ADAS power supplies. Its P600 package provides mechanical robustness and thermal mass needed for high-temperature PCB mounting, and its unidirectional configuration aligns with standard 24 V DC bus protection schemes. The 5KP24HE3/73 has been validated for load dump immunity per ISO 7637-2 Pulse 5a, supporting design compliance without additional external thermal management in most implementations.
How does the 5KP24HE3/73 differ from the 5KP24A variant?
The 5KP24HE3/73 differs from the base 5KP24A by its HE3 suffix, indicating AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and RoHS compliance-whereas standard 5KP24A carries only commercial-grade E3 qualification. Both share identical electrical parameters (VWM = 24 V, VC = 38.9 V, PPPM = 5000 W), but the 5KP24HE3/73 undergoes extended reliability testing including temperature cycling, humidity bias, and high-temperature operating life. The 5KP24HE3/73 is the recommended part for automotive and mission-critical industrial designs where long-term field reliability is mandated.
What is the maximum allowable lead temperature during soldering for the 5KP24HE3/73?
The 5KP24HE3/73 supports solder dip at a maximum temperature of 275 °C for up to 10 seconds, per JESD 22-B106. This specification applies to wave soldering and manual tinning processes. For reflow soldering, Vishay recommends following the P600 package profile with peak temperature ≤ 260 °C and time above liquidus ≤ 60 seconds. Exceeding these limits risks delamination of the epoxy mold compound or degradation of the glass-passivated junction. The 5KP24HE3/73's matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring reliable wetting and intermetallic formation during all approved soldering methods.
Can the 5KP24HE3/73 be used in bidirectional configurations?
No, the 5KP24HE3/73 is unidirectional only, with polarity indicated by a cathode band. It conducts in reverse breakdown mode to clamp positive transients on the cathode side but blocks conduction in forward bias beyond ~3.5 V. For bidirectional protection (e.g., AC lines or differential data buses), two 5KP24HE3/73 devices must be connected in series opposition-or a dedicated bidirectional TVS such as the 5KP24CA should be selected. Using a single 5KP24HE3/73 in a bidirectional application leaves the circuit vulnerable to negative-going transients, as confirmed by its datasheet's "Polarity: Uni-directional" specification and absence of symmetrical VBR ratings.
