Product details
Overview
P6KE68HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 68 V breakdown voltage (VBR min = 64.6 V, max = 71.4 V), 58.1 V standoff voltage (VWM), 92.0 V clamping voltage at 6.5 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6KE68HE3/54 datasheet, P6KE68HE3/54 pinout, P6KE68HE3/54 application, or P6KE68HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C maximum junction temperature, 1.0 µA reverse leakage at VWM, glass-passivated junction, and RoHS-compliant matte tin-plated leads suitable for J-STD-002 soldering.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, clamping the line to ≤92.0 V at 6.5 A. Its 20 °C/W junction-to-lead thermal resistance enables effective heat dissipation during repetitive surge events.
The device uses a silicon avalanche structure with glass passivation for stable breakdown characteristics and long-term reliability. It is rated for uni-directional operation only (cathode-banded), with no bi-directional variant implied by the HE3/54 suffix - confirmed by absence of "CA" designation and presence of AEC-Q101 qualification (applies only to uni-directional P6KExxA-HE3 variants per datasheet note).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 64.6 V / 71.4 V - ensures reliable triggering above 58.1 V operating rail while avoiding false trips |
| VWM | 58.1 V - maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1.0 µA |
| VC @ IPPM | 92.0 V @ 6.5 A - clamping voltage limits downstream component stress during 10/1000 µs transients |
| PPPM | 600 W - peak surge power handling capability with industry-standard 10/1000 µs waveform |
| TJ max | 175 °C - supports operation in under-hood automotive and high-ambient industrial environments |

Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and alternator transients. IC Role / Device Role / Timing Role: Shunt clamping element placed between VBAT and chassis ground, triggered within <1 ns of overvoltage onset.

IC Role / Device Role / Timing Role: Primary-level surge suppressor before DC-DC converters, coordinated with MOVs and gas discharge tubes. Use Value: Provides precise 58.1 V clamping threshold and fast response to complement slower secondary protectors in multi-stage architectures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/57 | Lower peak power (400 W), smaller SMA package (DO-214AC), 64 V VBR, 55.1 V VWM | Surface-mount only; unsuitable for through-hole legacy designs or high-thermal-mass PCBs | Select when board space is constrained and 400 W surge rating suffices for IEC 61000-4-5 Level 3 compliance. |
| 1.5KE68A | Same DO-204AC package, identical VBR/VWM/VC, but commercial-grade (non-AEC-Q101), 1.5 kW peak power | Lacks automotive qualification; higher power rating requires larger PCB copper area for thermal management | Select for cost-sensitive industrial power supplies where AEC-Q101 is not mandated and 1.5 kW surge headroom is needed. |
Compared with SMAJ64A-E3/57 and 1.5KE68A, the P6KE68HE3/54 uniquely balances AEC-Q101 qualification, 600 W surge capability, and DO-204AC through-hole compatibility - making it optimal for automotive module replacements and industrial upgrades requiring drop-in reliability validation.

FAQ
What is the polarity configuration of P6KE68HE3/54?
P6KE68HE3/54 is a unidirectional TVS diode: the cathode is marked by a color band on the body, and it conducts only when the cathode is at higher potential than the anode. This configuration protects positive DC rails by shunting overvoltage to ground. The "A" suffix and absence of "CA" confirm unidirectional operation; the HE3/54 suffix denotes AEC-Q101 qualification and RoHS compliance.
Does P6KE68HE3/54 meet automotive qualification standards?
Yes, P6KE68HE3/54 is explicitly AEC-Q101 qualified per the Vishay datasheet (Document Number 88369, Revision 18-Sep-12, Note 1). This certification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its use in automotive powertrain, body, and infotainment systems where reliability under thermal and electrical stress is critical.
What is the maximum clamping voltage for P6KE68HE3/54 under surge conditions?
The maximum clamping voltage (VC) for P6KE68HE3/54 is 92.0 V, measured at 6.5 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is guaranteed across the full operating temperature range (−55 °C to +175 °C).
How does the thermal resistance of P6KE68HE3/54 affect PCB layout?
P6KE68HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W. To maintain safe junction temperatures during repetitive surges, PCB layout must provide low-thermal-resistance paths - such as ≥10 mm² copper pour connected to both leads - especially when operating near its 5.0 W steady-state power dissipation limit at 75 °C lead temperature.
Is P6KE68HE3/54 compatible with lead-free reflow processes?
P6KE68HE3/54 features matte tin-plated leads compliant with J-STD-002 for solderability and rated for solder dip at 275 °C for 10 seconds. While optimized for wave and hand soldering, it withstands standard lead-free reflow profiles (peak 260 °C) when mounted with appropriate pad geometry and thermal relief - verified by Vishay's qualification testing per JESD 22-B106.
