Product details
Overview
5KP24A-E3/73 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), 24.0 V stand-off voltage (VWM), and 38.9 V maximum clamping voltage (VC) at 129 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 5KP24A-E3/73 datasheet, 5KP24A-E3/73 pinout, 5KP24A-E3/73 application, or 5KP24A-E3/73 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with 275 °C solder dip per JESD 22-B106.
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protection device in parallel with sensitive circuitry. Its glass-passivated P600 junction enables fast response time (<1 ns), excellent clamping ratio (VC/VBR ≈ 1.46), and stable performance under repetitive 0.01% duty cycle transients.
Designed for switching power supply output protection, it replaces crowbar circuits by sustaining high IPPM without shorting-allowing upstream fuses or breakers to clear faults while preserving system reset capability. Thermal management relies on lead-frame conduction and PCB copper area, with 8.0 W steady-state dissipation at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24.0 V - Maximum continuous reverse operating voltage before breakdown; sets minimum system operating margin. |
| VBR @ IT | 26.7–29.5 V @ 5.0 mA - Breakdown voltage range defining turn-on threshold; ensures reliable triggering above nominal rail. |
| VC @ IPPM | 38.9 V @ 129 A - Clamped voltage during 10/1000 μs surge; determines protected circuit's maximum stress level. |
| PPPM | 5000 W - Peak pulse power handling capacity; defines survivability against lightning or inductive switch-off surges. |
| IFSM | 600 A - 8.3 ms half-sine surge current rating; supports single-event fault clearing without bond-wire failure. |
| TJ max | 175 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| Polarity | Unidirectional - Cathode-banded configuration; suitable for DC-biased rails only, not AC line protection. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; UL 94 V-0 rated; RoHS-compliant (E3 suffix); cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection to protected circuit ground or return path | Completes clamping path during overvoltage; must be routed with minimal inductance to avoid voltage overshoot. |
| Cathode | High-side connection to protected line (e.g., +24 V rail) | Marked by color band; connects to power rail requiring transient suppression; defines unidirectional conduction direction. |

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), smaller SMB package, same VWM (24 V), higher VC (38.9 V → 39.4 V) | Not AEC-Q101 qualified; limited to consumer/industrial use; unsuitable for automotive under-hood placement. | Select when board space is constrained and surge energy is ≤600 W; verify thermal derating on small pads. |
| 1.5KE24A | Same VWM (24 V), lower PPPM (1500 W), DO-201 package, higher VC (43.0 V), no AEC-Q101 qualification | Limited to low-energy transients; incompatible with ISO 7637-2 Pulse 5a (load dump); requires larger standoff distance. | Choose for cost-sensitive legacy designs where 1500 W surge immunity suffices and automotive qualification is not required. |
Compared with SMBJ24A and 1.5KE24A, the 5KP24A-E3/73 delivers 3.3× and 3.3× higher peak pulse power respectively, maintains AEC-Q101 compliance for automotive deployment, and achieves tighter clamping with lower incremental resistance-making it the only option rated for sustained 24 V rail protection in harsh environments.

FAQ
What is the clamping voltage of the 5KP24A-E3/73 under maximum rated surge current?
The 5KP24A-E3/73 has a maximum clamping voltage (VC) of 38.9 V at its rated peak pulse current (IPPM) of 129 A using the standardized 10/1000 μs waveform. This value is measured per JEDEC test conditions and represents the upper limit of voltage seen by protected circuitry during worst-case transient events. The 5KP24A-E3/73 maintains this clamping performance across its full operating temperature range.
Is the 5KP24A-E3/73 suitable for automotive applications?
Yes, the 5KP24A-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, robust P600 package, and validated performance against ISO 7637-2 load dump and jump-start transients make it appropriate for ECU, body control module, and ADAS power rail protection. The 5KP24A-E3/73 meets all mechanical and reliability requirements defined in the AEC-Q101 stress test standard.
How does the 5KP24A-E3/73 differ from the 5KP24CA variant?
The 5KP24A-E3/73 is unidirectional, while the 5KP24CA is bidirectional-meaning the 5KP24CA can protect AC-coupled or dual-polarity signals, whereas the 5KP24A-E3/73 is intended only for DC rails with defined polarity. Their VWM, VBR, and VC values differ accordingly: the 5KP24A-E3/73 has VWM = 24.0 V and VC = 38.9 V, while the 5KP24CA specifies symmetric parameters for both polarities. The 5KP24A-E3/73 cannot substitute for the 5KP24CA in AC or floating applications.
What is the maximum soldering temperature the 5KP24A-E3/73 can withstand?
The 5KP24A-E3/73 is rated for solder dip at 275 °C maximum for 10 seconds per JESD 22-B106, and is compatible with standard lead-free reflow profiles (peak ≤260 °C). Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability requirements. Exceeding 275 °C for longer than 10 s risks epoxy cracking or junction parameter shift. The 5KP24A-E3/73 retains full specification compliance after proper soldering.
Does the 5KP24A-E3/73 require a heatsink for continuous operation?
No, the 5KP24A-E3/73 does not require an external heatsink for transient suppression, as it is designed for non-repetitive pulse operation. Its 8.0 W steady-state power dissipation rating applies only when mounted on an infinite heatsink at TL = 75 °C-real-world PCB layout with ≥1 in² copper pour provides sufficient thermal relief for occasional surges. Continuous DC power dissipation is not a design use case for the 5KP24A-E3/73; it operates in clamping mode only during transients.
