Product details
Overview
P6KE30CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 30 V breakdown voltage (VBR min/max = 28.5–31.5 V at 1.0 mA), 41.4 V maximum clamping voltage (VC) at 14.5 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE30CAHE3/54 datasheet, P6KE30CAHE3/54 pinout, P6KE30CAHE3/54 application, or P6KE30CAHE3/54 equivalent, this AEC-Q101 qualified device offers verified bidirectional surge suppression, low clamping ratio (VC/VBR ≈ 1.38), and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering - critical for ESD and load-switch transient protection in safety-critical embedded designs.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction delivers fast response time (<1 ns) and low incremental surge resistance, ensuring reliable clamping before sensitive downstream components experience overvoltage stress.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, with thermal resistance RθJL = 20 °C/W (junction-to-lead). It meets UL 497B recognition (QVGQ2) and supports repetitive surge duty cycles up to 0.01 % with full 600 W pulse capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA - defines precise voltage threshold where clamping initiates in either polarity |
| VWM | 25.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 41.4 V at 14.5 A - clamped voltage seen by protected circuit during worst-case 10/1000 μs surge |
| PPPM | 600 W - peak transient energy absorption capacity under standardized surge waveform |
| IPPM | 14.5 A - maximum non-repetitive surge current the device safely clamps without failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | DO-214AA package; 33 V VBR; 52.8 V VC @ 11.3 A; same 600 W rating but lower IPPM | Surface-mount alternative with higher thermal resistance (RθJA = 110 °C/W vs. 75 °C/W for DO-15); better suited for PCB space-constrained designs | Select when automated SMT assembly is required and board layout allows reduced surge current margin. |
| 1.5KE33CA | Same DO-15 package; 33 V VBR; 53.3 V VC @ 11.3 A; 1500 W PPPM rating (10/1000 μs) | Higher power rating enables single-device protection for 24 V industrial buses; larger junction capacitance may affect high-speed signal integrity | Choose for 24 V systems needing headroom beyond 600 W, accepting slightly higher clamping voltage and larger physical size. |
Compared with SMBJ33CA and 1.5KE33CA, P6KE30CAHE3/54 provides optimal balance of AEC-Q101 qualification, 30 V standoff, and DO-15 through-hole manufacturability - making it preferred for automotive and industrial designs requiring proven reliability, manual serviceability, and precise 25.6 V working voltage alignment.

FAQ
What is the breakdown voltage range of the P6KE30CAHE3/54?
The P6KE30CAHE3/54 has a specified breakdown voltage (VBR) range of 28.5 V to 31.5 V at 1.0 mA test current, measured in both directions due to its bidirectional construction. This tight tolerance ensures consistent clamping behavior across production lots and temperature extremes, directly supporting designs requiring precise overvoltage thresholds such as 24 V system supervisors or 3.3 V logic rail protectors interfaced via level-shifting circuits.
Is the P6KE30CAHE3/54 suitable for automotive applications?
Yes, the P6KE30CAHE3/54 carries AEC-Q101 qualification (HE3 suffix), confirming validation for automotive use including temperature cycling, highly accelerated life testing, and ESD robustness. Its 175 °C maximum junction temperature, UL 497B recognition, and DO-15 mechanical stability make P6KE30CAHE3/54 appropriate for engine control units, body control modules, and infotainment power supplies where transient immunity and long-term reliability are mandatory.
How does the clamping voltage of P6KE30CAHE3/54 compare to its breakdown voltage?
The P6KE30CAHE3/54 clamps to a maximum of 41.4 V at 14.5 A peak pulse current (10/1000 μs), yielding a clamping ratio (VC/VBR) of approximately 1.38. This low ratio indicates efficient energy diversion with minimal overvoltage overshoot - critical for protecting 3.3 V or 5 V ICs whose absolute maximum ratings are often only 20–30 % above nominal supply, ensuring sustained functionality during repeated surge events.
What is the maximum steady-state power dissipation of the P6KE30CAHE3/54?
The P6KE30CAHE3/54 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. In typical PCB mounting, derating applies per Figure 5 of the datasheet - at 25 °C ambient, usable continuous power is ~3.5 W. This rating governs thermal design for sustained leakage or low-duty-cycle surge conditions, not transient clamping which relies on short-duration pulse capability.
Does the P6KE30CAHE3/54 have polarity markings for PCB layout?
No, the P6KE30CAHE3/54 is a bidirectional TVS and carries no polarity marking on the DO-15 package - consistent with its symmetrical internal structure. This eliminates orientation errors during manual assembly or rework and simplifies routing in AC-coupled or differential signal paths (e.g., RS-485, CAN, or audio lines), where polarity-independent protection is essential for robust field deployment.
