Product details
Overview
P6KE24CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 600 W peak pulse power (10/1000 μs), 24 V breakdown voltage (VBR min/max = 22.8 V / 25.2 V at IT = 1.0 mA), and clamps to ≤33.2 V at 18.1 A peak pulse current - used in automotive sensor signal lines and industrial I/O protection.
For engineers reviewing the P6KE24CA-E3/54 datasheet, P6KE24CA-E3/54 pinout, P6KE24CA-E3/54 application, or P6KE24CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C maximum junction temperature, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche breakdown in both polarities, enabling robust protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, critical for consistent clamping under repetitive transients.
Designed for unclamped transient energy absorption up to 600 W (10/1000 μs), it delivers fast response time (<1 ns) and maintains thermal stability via RθJL = 20 °C/W and TJmax = 175 °C - supporting high-reliability deployment in automotive ECUs and industrial PLC analog inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at IT = 1.0 mA - defines precise avalanche onset window for predictable clamping threshold |
| VWM | 20.5 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | ≤33.2 V at 18.1 A - peak clamped voltage during 600 W transient, limiting downstream stress |
| PPPM | 600 W (10/1000 μs) - surge handling capacity compatible with IEC 61000-4-5 Level 4 testing |
| TJmax | 175 °C - enables operation in under-hood automotive environments and sealed industrial enclosures |
| RθJL | 20 °C/W - supports direct PCB trace heat sinking without external heatsink in moderate-power applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | Same VBR range (22.8–25.2 V) but SMC package; 600 W rating; lower RθJA (40 °C/W vs. 75 °C/W) | Better thermal performance in high-density layouts; requires surface-mount reflow process instead of through-hole | Select SMBJ24CA when board space is constrained and automated assembly is available. |
| 1.5KE24CA | Same DO-15 package and VBR, but 1500 W peak power (10/1000 μs); higher IPPM (68.5 A) and VC (38.9 V) | Higher surge margin for harsher environments (e.g., railway traction control); larger voltage overshoot during clamping | Choose 1.5KE24CA where system-level surge tests exceed IEC 61000-4-5 Level 4 requirements. |

FAQ
What is the breakdown voltage tolerance for P6KE24CA-E3/54?
The P6KE24CA-E3/54 has a specified breakdown voltage range of 22.8 V to 25.2 V at test current IT = 1.0 mA, representing a ±5 % tolerance around the nominal 24 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable design margining in 24 V system protection schemes.
Is P6KE24CA-E3/54 suitable for automotive applications?
Yes, P6KE24CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use in engine control, body electronics, and sensor interface modules. Its 175 °C maximum junction temperature, glass-passivated junction, and DO-15 mechanical robustness meet automotive environmental and reliability requirements per the Vishay datasheet revision 27-Sep-2021.
How does the bidirectional configuration of P6KE24CA-E3/54 affect circuit layout?
The bidirectional nature of P6KE24CA-E3/54 eliminates polarity sensitivity - both terminals are electrically identical, allowing unrestricted orientation during placement. This simplifies PCB layout for AC-coupled signals, differential buses like RS-485, or floating sensor outputs where traditional unidirectional TVS diodes would require strict anode/cathode alignment.
What is the maximum clamping voltage of P6KE24CA-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE24CA-E3/54 is 33.2 V at peak pulse current IPPM = 18.1 A (10/1000 μs waveform). This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and must be verified against downstream IC absolute maximum ratings during system-level surge validation.
Does P6KE24CA-E3/54 require a heatsink for standard operation?
No, P6KE24CA-E3/54 does not require an external heatsink under typical surge duty cycles (0.01 % repetitive rate). Its RθJL = 20 °C/W and RθJA = 75 °C/W allow adequate thermal dissipation through PCB copper and lead frames; however, sustained high-frequency transients may necessitate enhanced copper pour or thermal vias per Vishay's derating curves in Figure 2.
