Product details
Overview
P6KE24A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary-side overvoltage protection of DC power rails and signal lines. It features 22.8 V to 25.2 V breakdown voltage (VBR) at 1 mA, 20.5 V stand-off voltage (VWM), 33.2 V maximum clamping voltage (VC) at 18.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the P6KE24A-E3/54 datasheet, P6KE24A-E3/54 pinout, P6KE24A-E3/54 application, or P6KE24A-E3/54 equivalent, this page delivers verified electrical parameters, DO-15 terminal polarity mapping, clamping performance under surge conditions, thermal derating behavior, and AEC-Q101-qualified alternatives for automotive-grade transient suppression.
Technical Context
The P6KE24A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to ESD and lightning-induced transients. Its unidirectional polarity uses cathode-band marking, and it exhibits 0.094 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across -55 °C to +175 °C operating range.
Clamping is defined by VC = 33.2 V at IPPM = 18.1 A (10/1000 μs), with low incremental surge resistance and 1.0 μA max reverse leakage at VWM. Thermal resistance is RθJL = 20 °C/W (junction-to-lead), supporting reliable power dissipation up to 5.0 W on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 22.8 V / 25.2 V at IT = 1 mA - defines minimum voltage at which avalanche conduction begins reliably |
| VWM | 20.5 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 33.2 V at 18.1 A (10/1000 μs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient power handling capability without failure under standardized surge waveform |
| IFSM | 100 A (8.3 ms half-sine) - surge current rating for unidirectional forward conduction during fault events |
| TJ max | +175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pour design and thermal relief layout |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Cathode identified by color band; no marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path (unidirectional) | Connected to lower-potential side of protected line; conducts during positive surges when cathode is biased higher |
| Cathode (banded end) | Avalanche clamping node | Connected to higher-potential rail (e.g., VCC); initiates breakdown when reverse voltage exceeds VWM |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable avalanche characteristics and long-term reliability under repeated surge stress |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity in industrial power supply inputs |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including body control modules and sensor front-ends |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes overvoltage stress on downstream ICs such as CAN transceivers or microcontrollers |
| UL 94 V-0 molded compound | Meets flammability requirements for enclosed industrial enclosures and automotive junction boxes |
Applications
| Automotive Sensor Protection | Industrial PLC Digital Input |

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-E3/52 | DO-214AA package; 30.0 V VC @ 19.7 A; 600 W rating; same VBR range but lower clamping voltage | Better suited for space-constrained SMT layouts; requires rework of footprint and thermal pad design | Select when board real estate is limited and surface-mount assembly is preferred over through-hole DO-15. |
| 1.5KE24A | Same DO-15 package; 35.5 V VC @ 16.9 A; 1500 W peak power; higher VC and larger thermal mass | Higher energy absorption for infrequent but severe surges; less precise clamping for sensitive ICs | Choose for legacy designs requiring higher single-pulse energy handling where 35.5 V clamping is acceptable. |
Compared with SMBJ24A-E3/52 and 1.5KE24A, the P6KE24A-E3/54 offers optimal balance of compact DO-15 form factor, 33.2 V clamping precision, and AEC-Q101 qualification - making it ideal for new automotive and industrial designs where reliability, size, and standardized qualification converge.

FAQ
What is the breakdown voltage tolerance for P6KE24A-E3/54?
The P6KE24A-E3/54 has a specified breakdown voltage range of 22.8 V to 25.2 V at test current IT = 1 mA, representing ±10 % tolerance around the nominal 24 V rating. This tolerance is guaranteed per Vishay document 88369 and applies to all units meeting the E3 commercial grade specification.
Is P6KE24A-E3/54 RoHS compliant and halogen-free?
Yes, the P6KE24A-E3/54 carries the E3 suffix, indicating full RoHS compliance per EU Directive 2011/65/EU and halogen-free status per IEC 61249-2-21. The molding compound meets UL 94 V-0 flammability rating, and terminals are matte tin plated per J-STD-002.
Does P6KE24A-E3/54 meet AEC-Q101 for automotive use?
The P6KE24A-E3/54 is AEC-Q101 qualified per note (1) in the Vishay datasheet 88369. This qualification covers temperature cycling, humidity testing, and surge endurance - confirming suitability for automotive body electronics, sensor modules, and infotainment power supplies.
What is the maximum clamping voltage of P6KE24A-E3/54 under surge conditions?
The P6KE24A-E3/54 clamps to a maximum of 33.2 V when subjected to a 10/1000 μs waveform with peak current IPPM = 18.1 A. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuits during transient events.
How does thermal derating affect P6KE24A-E3/54 power handling above 25 °C?
Power dissipation of P6KE24A-E3/54 must be linearly derated above 25 °C ambient, with zero power allowed at +175 °C junction temperature. At 75 °C lead temperature (TL), its rated power drops to 5.0 W per Fig. 5 in datasheet 88369 - requiring adequate PCB copper area or heatsinking for sustained operation.
