Product details
Overview
P6KE120CAHE3/54 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 a 120 V breakdown voltage (VBR min/max = 114 V / 126 V), 102 V standoff voltage (VWM), 165 V maximum clamping voltage at 3.6 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 P6KE120CAHE3/54 datasheet, P6KE120CAHE3/54 pinout, P6KE120CAHE3/54 application, or P6KE120CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its bidirectional symmetry enables protection of AC-coupled or differential signal paths without polarity constraints.
Clamping performance is defined at IPPM = 3.6 A (10/1000 μs), delivering VC ≤ 165 V while maintaining low incremental surge resistance. Thermal design relies on RθJL = 20 °C/W to dissipate 5.0 W continuous power at TL = 75 °C, with junction temperature rated up to 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 114 V / 126 V at IT = 1.0 mA - defines precise voltage threshold where clamping begins in both directions |
| VWM | 102 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 165 V at 3.6 A (10/1000 μs) - limits worst-case transient voltage seen by downstream circuitry |
| PPPM | 600 W - peak surge energy handling capacity per single transient event |
| RθJL | 20 °C/W - enables thermal management via PCB copper pour or lead-frame heat sinking |
| TJ max. | 175 °C - supports operation in under-hood automotive and high-ambient industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Dimensions: 3.3–3.5 mm diameter × 25.4 mm minimum length; lead spacing ≥ 6.15 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Reversible terminal pair | No polarity marking; symmetric conduction in either direction - connects across protected line and return path |
| Leads (both ends) | Current-carrying terminals | Designed for through-hole mounting; thermal path to PCB copper or chassis ground via lead frame |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5 %) and long-term leakage stability under humidity and bias stress |
| 600 W 10/1000 μs surge rating | Withstands repetitive 3.6 A transients at 0.01 % duty cycle - suitable for motor commutation and relay switching noise |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics applications requiring zero early-life failure |
| UL 497B recognition (QVGQ2) | Meets safety standard for telecom/data line protectors - simplifies system-level certification |
| RoHS-compliant HE3 suffix | Indicates AEC-Q101 qualified, JESD 201 Class 2 whisker-resistant finish for high-reliability assembly |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Shunt clamping element placed between power rail and ground to clamp spikes above 102 V. Use Value: Limits voltage to ≤165 V during 3.6 A surges, preventing damage to MCU power supplies and CAN transceivers. |
Use Scenario: Safeguarding analog outputs of pressure/temperature sensors connected to PLC I/O modules. IC Role / Device Role / Timing Role: Bidirectional transient suppressor across differential signal pairs (e.g., 4–20 mA loop lines). Use Value: Maintains signal integrity by clamping ±165 V transients without polarity dependency or DC offset introduction. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Control |
Use Scenario: Secondary protection on Ethernet PHY or DSL line drivers exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Final-stage TVS after gas discharge tube (GDT) primary suppression, absorbing residual energy. Use Value: Fast <1 ns response ensures clamping occurs before GDT arc-over completes, reducing let-through energy. |
Use Scenario: Suppressing inductive kickback from brushed DC motors in washing machines or HVAC blowers. IC Role / Device Role / Timing Role: Across motor terminals to clamp reverse EMF during PWM switching transitions. Use Value: Handles 600 W peak pulses without degradation, extending life of driver MOSFETs and optocouplers. |
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; lower RθJA (50 °C/W vs. 75 °C/W); same VBR/VC specs | Better suited for surface-mount layouts with limited board space; requires reflow-compatible footprint | Select SMBJ120CA when SMT assembly and higher power density are prioritized over through-hole serviceability. |
| 1.5KE120CA | Higher PPPM = 1500 W; larger DO-201AD package; identical VBR, VWM, VC | Used where legacy 1.5 kW surge standards apply (e.g., IEC 61000-4-5 Level 4) or higher single-event margin is required | Choose 1.5KE120CA only if system-level testing mandates >600 W single-pulse capability - adds cost and board area. |
Compared with SMBJ120CA and 1.5KE120CA, P6KE120CAHE3/54 delivers optimal balance of AEC-Q101 qualification, DO-15 through-hole robustness, and UL 497B recognition - making it preferred for automotive and industrial through-hole designs where reliability and certification alignment outweigh raw power rating.

FAQ
What is the clamping voltage of P6KE120CAHE3/54 under standard test conditions?
The P6KE120CAHE3/54 has a maximum clamping voltage (VC) of 165 V when subjected to a 10/1000 μs waveform at IPPM = 3.6 A. This value is measured per JEDEC standards and reflects worst-case voltage let-through during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings. The P6KE120CAHE3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE120CAHE3/54 suitable for automotive applications?
Yes, P6KE120CAHE3/54 is AEC-Q101 qualified and carries the HE3 suffix denoting compliance with JESD 201 Class 2 whisker resistance - confirming suitability for automotive powertrain, body control, and infotainment systems. Its 175 °C junction rating, UL 497B recognition, and DO-15 mechanical robustness make P6KE120CAHE3/54 appropriate for under-hood and dashboard-mounted electronics.
How does the bidirectional configuration of P6KE120CAHE3/54 affect circuit placement?
The bidirectional nature of P6KE120CAHE3/54 means it has no anode/cathode marking and conducts identically in both directions - enabling placement across AC-coupled lines, differential buses (e.g., RS-485), or ungrounded power rails without orientation concerns. Unlike unidirectional TVS diodes, P6KE120CAHE3/54 eliminates risk of incorrect polarity installation during manual assembly or field repair.
What is the standoff voltage rating for P6KE120CAHE3/54, and why does it matter?
P6KE120CAHE3/54 has a standoff voltage (VWM) of 102 V - the maximum continuous DC or RMS voltage it can block without exceeding 1.0 μA leakage. This parameter ensures reliable operation in 90–100 V nominal systems (e.g., 12 V automotive with load dump derating) while avoiding false triggering. Exceeding VWM risks accelerated aging or premature clamping in P6KE120CAHE3/54.
Does P6KE120CAHE3/54 require heatsinking in typical applications?
P6KE120CAHE3/54 does not require external heatsinking for single-event surge suppression, as its 600 W rating applies to non-repetitive pulses. However, for sustained power dissipation, its RθJL = 20 °C/W necessitates adequate PCB copper area (≥1 cm² per lead) or chassis contact to maintain TJ ≤ 175 °C. At 5.0 W continuous load, P6KE120CAHE3/54 reaches thermal limit without thermal relief.
