Product details
Overview
5KP24AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 24.0 V stand-off voltage (VWM), 26.7–29.5 V breakdown voltage (VBR) at 5.0 mA, 38.9 V maximum clamping voltage (VC) at 129 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used in automotive power supply input stages.
For engineers reviewing the 5KP24AHE3/54 datasheet, 5KP24AHE3/54 pinout, 5KP24AHE3/54 application, or 5KP24AHE3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, peak surge current capability under lightning/inductive-switching transients, thermal derating above 25 °C, and AEC-Q101 qualification status for automotive deployment.
Technical Context
The 5KP24AHE3/54 operates as a silicon avalanche diode with glass-passivated P600 junction, optimized for non-repetitive transient suppression. Its unidirectional polarity enables use on positive-rail protection only, with cathode marked by color band. Clamping begins near VBR and stabilizes at VC = 38.9 V under 129 A, limiting energy dissipation to protect downstream MOSFETs or controllers.
It complies with JEDEC registered test conditions: 10/1000 μs waveform, 0.01 % duty cycle, and 8.3 ms half-sine surge rating up to 500 A. Thermal performance is defined per Fig. 5 - power derates linearly from 8.0 W at TL = 75 °C to zero at TJ = 175 °C - requiring adequate PCB copper area or heatsinking for sustained surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24.0 V - maximum continuous reverse voltage before leakage exceeds 2.0 μA; sets upper limit for normal operating rail voltage. |
| VBR min/max | 26.7 V / 29.5 V at 5.0 mA - guaranteed avalanche initiation range; ensures consistent turn-on across production lots. |
| VC @ IPPM | 38.9 V at 129 A - clamped voltage during worst-case 10/1000 μs surge; must be below protected device's absolute max rating. |
| PPPM | 5000 W - peak transient power handling capacity; defines survivability against IEC 61000-4-5 Level 4 surges. |
| IFSM | 500 A - 8.3 ms single half-sine surge rating; supports crowbar-style fault clearing without fuse blow delay. |
| TJ max | +175 °C - maximum junction temperature; enables operation in under-hood automotive environments. |
| Polarity | Unidirectional - cathode-marked device; requires correct orientation in series with positive supply rail. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; RoHS-compliant, AEC-Q101 qualified, UL 94 V-0 rated. Cathode indicated by color band. Lead finish meets J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Connected to ground or low-side reference | Current sink path during transient; must tie to low-impedance ground plane to minimize L × di/dt voltage overshoot. |
| Cathode | Connected to protected line (e.g., +24 V rail) | Marked by color band; reverse-biased during normal operation; conducts when Vin > VBR to clamp overvoltage. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24AHE3/52 | Lower PPPM (600 W), smaller SMB package, same VWM/VBR/VC specs | Targeted at space-constrained consumer electronics; insufficient for ISO 7637-2 load dump | Select 5KP24AHE3/54 when peak surge energy exceeds 600 W or AEC-Q101 qualification is mandatory. |
| 1.5KE24A | Same VWM/VBR/VC but lower PPPM (1500 W), DO-201 package, no AEC-Q101 qualification | Legacy industrial designs with lower surge severity; not suitable for automotive OEM programs | Choose 5KP24AHE3/54 for new automotive or high-reliability industrial designs requiring 5000 W rating and automotive qualification. |
Compared with SMBJ24AHE3/52 and 1.5KE24A, the 5KP24AHE3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, maintains identical clamping performance at higher current, and provides certified AEC-Q101 reliability - making it the sole option for demanding automotive power rail protection where sustained surge energy and qualification compliance are non-negotiable.

FAQ
What is the clamping voltage of the 5KP24AHE3/54 under maximum rated surge current?
The 5KP24AHE3/54 has a maximum clamping voltage (VC) of 38.9 V when subjected to its rated peak pulse current (IPPM) of 129 A using a 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuitry will not experience voltages exceeding 38.9 V during such transient events, provided layout minimizes parasitic inductance. The 5KP24AHE3/54 achieves this clamping with low incremental surge resistance for tight voltage control.
Is the 5KP24AHE3/54 suitable for bidirectional transient protection?
No, the 5KP24AHE3/54 is unidirectional only, with cathode marked by a color band. It conducts only when the anode is negative relative to the cathode - meaning it protects positive-rail overvoltages only. For bidirectional protection (e.g., AC lines or data lines with ± transients), a separate bidirectional part such as 5KP24CAHE3/54 would be required. The 5KP24AHE3/54 datasheet explicitly states "Available in unidirectional polarity only" and does not specify symmetrical breakdown behavior.
Does the 5KP24AHE3/54 require a heatsink for standard automotive operation?
The 5KP24AHE3/54 does not require an external heatsink for single-event transient suppression, as energy is dissipated in <1 ms. However, for repeated surges or elevated ambient temperatures, PCB copper area ≥ 250 mm² per lead is recommended to maintain junction temperature ≤175 °C. Its 8.0 W steady-state power rating applies only with infinite heatsink at TL = 75 °C - a condition not typical in automotive harness-mounted use. The 5KP24AHE3/54 relies on short-duration thermal mass, not continuous conduction.
How does the AEC-Q101 qualification of the 5KP24AHE3/54 impact its use in automotive designs?
The AEC-Q101 qualification of the 5KP24AHE3/54 certifies its reliability for automotive under-hood applications, including temperature cycling, humidity bias, mechanical shock, and lifetime surge endurance testing. This qualification allows direct inclusion in OEM Tier 1 BOMs without additional component-level qualification. Unlike non-qualified alternatives, the 5KP24AHE3/54 provides documented failure mode analysis and lot traceability - critical for functional safety compliance in ASIL-B systems where the 5KP24AHE3/54 serves as a hardware fault tolerance element.
What is the lead finish and solderability specification for the 5KP24AHE3/54?
The 5KP24AHE3/54 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 for solderability, and meets JESD 201 Class 2 for whisker resistance. Solder dip is rated up to 275 °C for 10 seconds per JESD 22-B106. This finish ensures robust reflow and wave solder joint integrity in high-volume automotive manufacturing, with immunity to tin whisker growth over 15+ years - a requirement validated under AEC-Q101 stress testing. The 5KP24AHE3/54's lead finish directly supports IPC-A-610 Class 3 assembly standards.
