Product details
Overview
P6KA24AHE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 22.8 V to 25.2 V breakdown voltage (VBR), 20.5 V standoff voltage (VWM), 600 W peak pulse power (10/1000 μs), 18.1 A peak pulse current (IPPM), and clamps to ≤33.6 V at rated surge - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6KA24AHE3/54 datasheet, P6KA24AHE3/54 pinout, P6KA24AHE3/54 application, or P6KA24AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, DO-204AC (DO-15) package compatibility, and verified clamping performance under repetitive 0.01% duty cycle transients.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation up to TJ = 185 °C. Its unidirectional polarity and low incremental surge resistance enable precise clamping during fast-rising inductive switching transients.
The device meets JEDEC JESD22-B106 solderability requirements (275 °C, 10 s) and JESD201 Class 2 whisker resistance. Its 10/1000 μs waveform response delivers consistent 600 W surge handling with <1 ns intrinsic response time and minimal capacitance (<100 pF at VWM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 20.5 V - maximum continuous reverse working voltage compatible with 24 V nominal systems |
| IPPM | 18.1 A - peak surge current capability at 10/1000 μs waveform, sufficient for ISO 7637-2 Pulse 1 & 2a suppression |
| VC (max) | 33.6 V - clamped voltage under full IPPM, maintaining downstream ICs below absolute maximum ratings |
| PPPM | 600 W - standardized surge energy absorption per 10/1000 μs waveform, enabling predictable PCB layout margining |
| TJ max. | +185 °C - supports under-hood automotive placement without derating in high-ambient environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; cathode denoted by color band; RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to protected line (e.g., 24 V rail or signal trace); forms low-impedance shunt to ground during overvoltage |
| Cathode | Clamping reference / surge sink | Connected to system ground; defines VBR threshold and establishes clamping voltage relative to GND |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | TJ = 185 °C enables use in engine control modules and powertrain electronics without thermal derating |
| AEC-Q101 qualification | Validated for automotive applications including temperature cycling, HTRB, and ESD per stress test plan |
| Low clamping ratio (VC/VBR) | ≤1.48 - minimizes overvoltage stress on downstream MOSFETs and microcontrollers during surge events |
| Fast response time | <1 ns intrinsic turn-on - intercepts sub-microsecond transients before they propagate into IC inputs |
| Solderability & whisker resistance | Meets JESD 22-B106 (275 °C, 10 s) and JESD 201 Class 2 - ensures long-term reliability in reflow and wave solder processes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5A (Vishay) | Same DO-214AC package; lower PPPM (400 W); higher VC (38.9 V); identical VWM (20.5 V) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a load dump simulation | Select P6KA24AHE3/54 when 600 W surge headroom and tighter clamping are required in automotive or industrial 24 V systems. |
| 1.5KE24A (ON Semiconductor) | DO-201AD package; same VWM (20.5 V); higher VC (38.7 V); larger footprint; no AEC-Q101 qualification | Not qualified for automotive use; requires larger PCB area; less suitable for high-density layouts | Choose P6KA24AHE3/54 for space-constrained, AEC-Q101–mandated designs where thermal robustness and compact DO-15 form factor are critical. |
Compared with SMAJ24A-E3/5A and 1.5KE24A, the P6KA24AHE3/54 delivers superior surge margin (600 W vs. 400 W/1500 W), tighter clamping (33.6 V vs. 38.9 V/38.7 V), and automotive qualification in a smaller DO-15 package - making it optimal for next-generation 24 V ECU and sensor node protection.

FAQ
What is the maximum clamping voltage of the P6KA24AHE3/54 under rated surge conditions?
The P6KA24AHE3/54 has a maximum clamping voltage (VC) of 33.6 V when subjected to its rated 18.1 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components remain within safe operating limits during transient events. The P6KA24AHE3/54 achieves this clamping performance consistently across its operational temperature range.
Is the P6KA24AHE3/54 qualified for automotive applications?
Yes, the P6KA24AHE3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge per the AEC-Q101 standard. Its 185 °C maximum junction temperature and DO-204AC construction make it suitable for under-hood and powertrain applications. The P6KA24AHE3/54 is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What package type does the P6KA24AHE3/54 use, and what are its key mechanical features?
The P6KA24AHE3/54 uses the DO-204AC (DO-15) package: axial-leaded, molded epoxy case with 0.375" (9.5 mm) body length and 0.140" (3.6 mm) diameter. Leads are matte tin-plated, compliant with J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance. The cathode is marked by a color band. The P6KA24AHE3/54's package supports manual and automated assembly with 275 °C solder dip tolerance.
How does the P6KA24AHE3/54 differ from the P6KA24 variant?
The P6KA24AHE3/54 has tighter VBR tolerance (22.8 V to 25.2 V) versus P6KA24 (21.6 V to 26.4 V), resulting in more predictable turn-on behavior and lower clamping variation. It also exhibits improved temperature coefficient (0.094 %/°C) and lower leakage at elevated temperatures. Both share identical package, power rating, and AEC-Q101 qualification, but the P6KA24AHE3/54 is preferred for precision-critical 24 V protection where consistent clamping is essential.
Can the P6KA24AHE3/54 be used in bidirectional protection configurations?
No - the P6KA24AHE3/54 is unidirectional only, with a defined anode and cathode. It conducts only during positive transients relative to its cathode connection. For true bidirectional protection, two P6KA24AHE3/54 devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., P6SMB24A) should be selected. The P6KA24AHE3/54 datasheet explicitly states "Available in uni-directional polarity only" and provides no bidirectional specifications.
