Product details
Overview
P6KE120HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 120 V breakdown voltage (VBR = 114–126 V at IT = 1.0 mA), 102 V maximum stand-off voltage (VWM), 165 V clamping voltage (VC) at 3.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECU power inputs and industrial sensor interfaces.
For engineers reviewing the P6KE120HE3/54 datasheet, P6KE120HE3/54 pinout, P6KE120HE3/54 application, or P6KE120HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package, 175 °C max junction temperature, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM = 102 V, it avalanches into low-impedance conduction to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage (<1.0 µA at VWM).
Designed for unidirectional DC line protection, P6KE120HE3/54 exhibits fast response time (<1.0 ns), low incremental surge resistance, and thermal robustness via RθJL = 20 °C/W and RθJA = 75 °C/W - enabling reliable operation without heatsinking in ambient temperatures up to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 114 V / 126 V at IT = 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping behavior |
| 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 protected circuit voltage during worst-case surge |
| PPPM | 600 W - sustains single high-energy transients common in automotive load-dump and inductive switching |
| TJ max | +175 °C - supports under-hood automotive placement and high-temperature industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.300" lead spacing, UL 94 V-0 molding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with matte tin-plated leads; cathode indicated by color band on one end; compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-potential return path; completes shunt path during avalanche conduction |
| Cathode | Protected line input | Connected to DC rail or signal line being safeguarded; color band identifies this terminal |
Key Features

| 600 W peak pulse power (10/1000 µs) | Withstands automotive load-dump surges (ISO 7637-2 Pulse 5a) without degradation |
| AEC-Q101 qualification | Validated for automotive electronics including engine control units and body controllers |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage stress on downstream MOSFETs and microcontrollers during clamping |
| UL 94 V-0 flammability rating | Meets safety requirements for enclosed industrial and transportation equipment housings |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
|
Use Scenario: 12 V battery-fed ECU power rail exposed to ISO 7637-2 load-dump transients up to 60 V for 400 ms. IC Role / Device Role / Timing Role: Shunt TVS device placed between VBAT and GND to clamp surges before they reach LDO regulators and MCU power pins. Use Value: Limits rail voltage to ≤165 V during 3.6 A surge, preventing permanent damage to 3.3 V/5 V logic and analog front-ends. |
Use Scenario: 24 V analog sensor output (e.g., pressure transducer) routed across noisy factory floor wiring. IC Role / Device Role / Timing Role: Uni-directional TVS connected anode-to-GND, cathode-to-signal line to suppress ESD and inductive kickback. Use Value: Clamps fast transients (<1 ns rise) to <165 V while maintaining <1.0 µA leakage at 24 V nominal, preserving signal integrity. |
| DC Motor Drive Flyback Suppression | Telecom Line Interface Surge Guard |
|
Use Scenario: H-bridge motor driver PCB where flyback energy from 24 V brushed DC motors induces >100 V spikes on supply rails. IC Role / Device Role / Timing Role: Primary rail clamp mounted near motor terminals to absorb inductive energy before it propagates to logic sections. Use Value: Absorbs 600 W peak pulses without thermal runaway, leveraging RθJL = 20 °C/W for self-cooling through PCB copper pours. |
Use Scenario: RS-485 interface on telecom base station board subjected to lightning-induced surges on long outdoor cable runs. IC Role / Device Role / Timing Role: Secondary-level protection staged after gas discharge tube (GDT), providing low-VC clamping for sensitive PHY ICs. Use Value: Delivers 165 V clamping at 3.6 A with <1 ns response, reducing residual surge stress on TI SN65HVD72 or similar transceivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A | Same VBR range (114–126 V), but SMC package (surface-mount); 600 W rating; lower VC = 165 V | Requires PCB rework for SMT layout; better for high-density boards where axial leads are impractical | Select SMBJ120A when automated assembly and space constraints outweigh axial lead serviceability needs |
| 1.5KE120A | Same DO-204AC package and VBR, but higher PPPM = 1500 W; VC = 193 V at 7.8 A | Higher surge margin for infrequent extreme events (e.g., direct lightning coupling), but larger VC overshoot | Choose 1.5KE120A only if system-level testing confirms 193 V clamping is acceptable for protected ICs |
Compared with SMBJ120A and 1.5KE120A, P6KE120HE3/54 offers AEC-Q101 qualification and optimized cost-performance balance for volume automotive and industrial applications - delivering verified 165 V clamping in a qualified, through-hole package without over-specifying surge capacity.

FAQ
What is the maximum clamping voltage of P6KE120HE3/54 under standard test conditions?
The maximum clamping voltage (VC) of P6KE120HE3/54 is 165 V when subjected to a 10/1000 µs waveform peak pulse current of 3.6 A. This value is measured per JEDEC standards and reflects the upper limit of voltage seen by protected circuitry during surge events - critical for ensuring downstream ICs rated for ≤200 V absolute maximum survive transient exposure. The P6KE120HE3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE120HE3/54 suitable for automotive applications?
Yes, P6KE120HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, matte tin-plated leads compliant with JESD 201 Class 2 whisker resistance, and operation up to +175 °C junction temperature - meeting requirements for engine control units, body electronics, and ADAS power supplies. The HE3 suffix denotes AEC-Q101 qualification, distinguishing it from commercial-grade E3 variants.
What does the "HE3/54" suffix mean in P6KE120HE3/54?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery with 4000 units per reel. This ordering format aligns with Vishay's standardized part numbering - confirming both reliability grade and logistics configuration for P6KE120HE3/54 in production environments.
How does P6KE120HE3/54 differ from bi-directional P6KE120CA variants?
P6KE120HE3/54 is uni-directional, with a defined anode and cathode (cathode marked by color band), intended for DC line protection where polarity is fixed. In contrast, P6KE120CA is bi-directional - symmetrical in both directions, no polarity marking - used in AC-coupled or floating signal paths. Their VBR and VC values differ: P6KE120CA has VBR = 114–126 V bidirectionally but higher VC due to dual-junction structure, making P6KE120HE3/54 preferable for polarized 12/24 V systems.
What is the thermal resistance specification for P6KE120HE3/54?
P6KE120HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W at TA = 25 °C. These values enable effective heat dissipation through PCB copper pours or chassis mounting - allowing the device to sustain repeated 600 W surges without exceeding its 175 °C maximum junction temperature, provided lead temperature (TL) remains ≤75 °C per derating curve Fig. 5.
