Product details
Overview
P6KE120CA-E3/54 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 120 V breakdown voltage (VBR min/max = 114 V / 126 V), 165 V maximum clamping voltage at 3.6 A peak pulse current, and 600 W peak pulse power dissipation with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE120CA-E3/54 datasheet, P6KE120CA-E3/54 pinout, P6KE120CA-E3/54 application, or P6KE120CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1.0 μA at 102 V), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamping protection element in both polarities, leveraging an avalanche breakdown mechanism to divert surge energy away from sensitive downstream circuitry. Its bidirectional symmetry ensures identical electrical behavior regardless of transient polarity, eliminating need for orientation-sensitive placement on PCBs.
Designed for transient suppression per IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT), it delivers sub-nanosecond response time and low dynamic impedance during clamping. Thermal resistance is specified at RθJL = 20 °C/W (junction-to-lead), enabling effective heat dissipation under repetitive surge conditions when mounted with adequate lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 114 V / 126 V at 1.0 mA test current - defines reliable conduction onset range for overvoltage protection |
| VWM | 102 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 165 V at 3.6 A - clamped voltage seen by protected circuit during worst-case 600 W surge |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform, supporting robust ESD/EFT immunity |
| TJ max | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for surge duty cycle derating |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTOL, TCT, and HAST |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120CA | DO-214AA package, 100 W lower peak pulse power (500 W), same VBR range and bidirectional configuration | Surface-mount alternative requiring PCB re-layout; better suited for high-density consumer boards | Select when automated assembly and smaller footprint outweigh axial-leaded mechanical robustness |
| 1.5KE120CA | Same DO-15 package but higher 1500 W peak pulse power, larger die size, higher clamping voltage (175 V) | Used where higher surge margin is required, e.g., outdoor telecom cabinets with direct lightning exposure | Choose only if system-level testing confirms need for >600 W rating; otherwise P6KE120CA-E3/54 offers optimal cost/performance balance |
Compared with SMBJ120CA and 1.5KE120CA, P6KE120CA-E3/54 delivers the best trade-off of proven automotive qualification, axial-leaded serviceability, and sufficient 600 W surge capacity for most industrial and automotive subsystems - avoiding over-engineering while meeting AEC-Q101 and UL 94 V-0 requirements.

FAQ
What is the maximum clamping voltage of the P6KE120CA-E3/54 under full-rated surge conditions?
The P6KE120CA-E3/54 has a maximum clamping voltage (VC) of 165 V at 3.6 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value represents the highest voltage the protected circuit will experience during a 600 W transient event. The P6KE120CA-E3/54 maintains this clamping performance across its full operating temperature range of -55 °C to +175 °C, ensuring consistent protection in harsh environments.
Is the P6KE120CA-E3/54 suitable for automotive applications?
Yes, the P6KE120CA-E3/54 is AEC-Q101 qualified and explicitly listed in Vishay's documentation as meeting automotive reliability requirements. Its 175 °C maximum junction temperature, glass-passivated junction, and UL 94 V-0 molding compound make it appropriate for under-hood and body-control module applications. The P6KE120CA-E3/54 is commonly deployed in LIN bus protection, lighting control, and power distribution units where bidirectional transient suppression is required.
How does the bidirectional design of the P6KE120CA-E3/54 affect PCB layout?
The P6KE120CA-E3/54 has no polarity marking and functions identically in either orientation, simplifying PCB layout and eliminating risk of incorrect installation. Unlike unidirectional TVS diodes, it requires no attention to cathode band alignment during placement or assembly. This symmetry allows flexible routing in differential signal paths or AC-coupled power rails, and reduces inventory complexity when multiple protection points share the same part number. The P6KE120CA-E3/54 is especially advantageous in designs where transient polarity cannot be predicted, such as antenna feedlines or transformer-coupled interfaces.
What is the leakage current specification for the P6KE120CA-E3/54 at its rated standoff voltage?
At its maximum steady-state reverse voltage (VWM) of 102 V, the P6KE120CA-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This ultra-low leakage ensures minimal power loss and signal interference in high-impedance sensor or communication circuits. The P6KE120CA-E3/54 maintains acceptable leakage levels even at elevated temperatures, supporting reliable operation in industrial environments up to 125 °C ambient without compromising system standby power budgets.
Can the P6KE120CA-E3/54 replace the unidirectional P6KE120A in existing designs?
No - the P6KE120CA-E3/54 is bidirectional and lacks polarity marking, whereas the P6KE120A is unidirectional with a cathode band. Substituting them requires verifying that the circuit does not rely on forward conduction or DC bias blocking in one direction. In purely AC or symmetric transient scenarios (e.g., Ethernet PHY protection), the P6KE120CA-E3/54 may function equivalently, but in DC power line applications, the P6KE120A provides intentional forward conduction path that the P6KE120CA-E3/54 does not replicate. Always validate clamping behavior and steady-state bias conditions before interchanging.
