Product details
Overview
P6KE24C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection of sensitive electronics in power and signal lines. It features a 24 V breakdown voltage (VBR = 22.8–25.2 V at IT = 1.0 mA), 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, industrial I/O protection, and DC power rail surge suppression.
For engineers reviewing the P6KE24C-E3/54 datasheet, P6KE24C-E3/54 pinout, P6KE24C-E3/54 application, or P6KE24C-E3/54 equivalent, key selection criteria include its bi-directional polarity, DO-204AC (DO-15) package, AEC-Q101 qualification (via HE3 variant), low 1.0 μA reverse leakage at 20.5 V stand-off, and thermal resistance of 75 °C/W junction-to-ambient - critical for high-reliability transient immunity in constrained layouts.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both forward and reverse directions, enabling robust protection against bidirectional transients such as ESD, lightning-induced surges, and inductive switching spikes. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the 20 °C/W junction-to-lead thermal resistance supports localized heat dissipation during repetitive pulses.
The P6KE24C-E3/54 is rated for 175 °C maximum junction temperature and exhibits a +0.094 %/°C temperature coefficient of VBR, ensuring predictable voltage drift across operating ranges. It complies with UL 497B recognition (QVGQ2) and meets JESD 22-B106 solderability requirements (275 °C, 10 s), confirming suitability for automated assembly in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1.0 mA test current - defines precise avalanche onset threshold for reliable clamping initiation |
| VWM | 20.5 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 33.2 V at 18.1 A - clamped voltage under 600 W 10/1000 μs surge, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling capability, enabling protection against severe transient events |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance, guiding heatsinking and layout decisions for sustained operation |
| TJ max. | 175 °C - maximum junction temperature, supporting operation in under-hood automotive and industrial ambient conditions |
| Leakage ID | 1.0 μA at VWM - minimal standby power loss and negligible loading on protected circuits |

IC Role / Device Role / Timing Role: Parallel-connected TVS across VIN and GND to shunt inductive switch-off energy from solenoids or relays. Use Value: Limits rail collapse to 33.2 V during 10/1000 μs surges, preserving brown-out immunity and avoiding reset faults in downstream logic. |
Use Scenario: Protecting Ethernet PHYs, RS-485 transceivers, and DSL line drivers from lightning-induced common-mode surges on twisted-pair cables. IC Role / Device Role / Timing Role: Bi-directional clamp on differential pair (e.g., A/B lines), referenced to local ground plane. Use Value: Symmetrical clamping ensures equal suppression of positive/negative transients, meeting ITU-T K.21 basic protection level requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24CA | Lower 400 W PPPM, SMA package (smaller footprint, higher RθJA = 110 °C/W), same VBR range and bi-directionality | Better suited for space-constrained consumer PCBs; less thermal margin in high-ambient industrial use | Select when board area is critical and surge energy rarely exceeds 400 W |
| 1.5KE24CA | Same DO-204AC package, identical VBR/VC, but 1500 W PPPM and higher IPPM (129 A) | Required for MIL-STD-1275 or ISO 16750-2 severe surge testing where 600 W is insufficient | Choose when system-level surge testing mandates >600 W headroom or legacy 1.5KE footprint compatibility is needed |
Compared with SMAJ24CA and 1.5KE24CA, the P6KE24C-E3/54 delivers optimal balance of surge robustness, thermal performance, and cost for mid-tier industrial and automotive applications - offering 600 W clamping with proven DO-15 manufacturability and AEC-Q101 traceability via HE3 variants.

FAQ
What is the polarity configuration of P6KE24C-E3/54?
The P6KE24C-E3/54 is a bi-directional TVS diode, meaning it functions identically in both forward and reverse bias - no cathode marking is present on the DO-204AC package. This symmetry allows it to suppress voltage transients of either polarity on AC-coupled or differential signal lines without orientation concerns during placement. The "C" suffix explicitly denotes bi-directional construction per Vishay's naming convention.
Does P6KE24C-E3/54 meet automotive qualification standards?
The P6KE24C-E3/54 itself is the commercial-grade (E3) version and is not AEC-Q101 qualified; however, its direct variant P6KE24CHE3/54 carries full AEC-Q101 qualification. Both share identical electrical parameters and DO-204AC packaging - only the whisker test class (E3 = JESD 201 Class 1A) and qualification status differ. For automotive designs, P6KE24CHE3/54 is the designated qualified part.
What is the maximum clamping voltage of P6KE24C-E3/54 under surge conditions?
The P6KE24C-E3/54 has a maximum clamping voltage (VC) of 33.2 V when subjected to its rated peak pulse current (IPPM) of 18.1 A using the standard 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet and represents the upper bound of voltage seen by downstream circuitry during worst-case transient events - critical for ensuring protected ICs remain within their absolute maximum voltage ratings.
How does P6KE24C-E3/54 compare to uni-directional P6KE24A-E3/54?
The P6KE24C-E3/54 differs from the uni-directional P6KE24A-E3/54 solely in polarity configuration: the "C" version is bi-directional with symmetrical VBR and VC in both directions, while the "A" version has a defined cathode band and only clamps in reverse bias. Their breakdown (22.8–25.2 V), clamping (33.2 V), and power (600 W) specs are identical - selection depends strictly on whether the protected circuit requires AC or bidirectional transient immunity.
What is the thermal resistance and maximum operating temperature of P6KE24C-E3/54?
The P6KE24C-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and a maximum junction temperature (TJ) of +175 °C. These values define its thermal envelope: at 5.0 W steady-state power dissipation (PD), ambient temperature must remain below 125 °C to avoid exceeding TJ max. In practice, the device handles short-duration 600 W pulses with minimal average heating due to its low thermal mass and specified pulse derating curves.
