Product details
Overview
P6KE350A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for overvoltage protection of sensitive electronics. It features 333 V minimum breakdown voltage (VBR), 300 V standoff voltage (VWM), 482 A peak pulse current (IPPM), and clamps transients to ≤482 V at rated surge, protecting power rails and signal lines in industrial and automotive systems.
For engineers reviewing the P6KE350A-E3/54 datasheet, P6KE350A-E3/54 pinout, P6KE350A-E3/54 application, or P6KE350A-E3/54 equivalent, key selection criteria include unidirectional polarity, 600 W 10/1000 μs surge rating, DO-15 mechanical compatibility, thermal resistance (RθJA = 75 °C/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and inductive switching events.
The device is rated for 600 W peak pulse power with 10/1000 μs waveform at 0.01 % duty cycle, dissipates 5.0 W continuously on infinite heatsink at TL = 75 °C, and supports 100 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave - critical for motor drive and relay coil suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 300 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VBR (min/max) | 333 V / 368 V at 1.0 mA - defines reliable avalanche onset range under standardized test conditions |
| VC @ IPPM | ≤482 V at 1.2 A - clamping voltage during full-rated 10/1000 μs surge, limiting downstream stress |
| IPPM | 1.2 A - peak pulse current capability derived from 600 W rating and VC, not theoretical max |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, informs PCB copper area and airflow requirements |
| Package | DO-15 (DO-204AC) - axial-leaded through-hole package with 0.242–0.258 inch body length, UL 94 V-0 compliant |
Pinout & Package
DO-15 (DO-204AC) package: axial-leaded, molded epoxy case with matte tin-plated leads; cathode indicated by color band on one end; lead spacing accommodates standard 0.375 inch (9.5 mm) PCB mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Avalanche conduction terminal | Connected to protected line (e.g., +12 V rail); conducts when line voltage exceeds VWM + margin |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures ±5 % VBR tolerance and long-term stability under thermal cycling and humidity |
| 600 W peak pulse power (10/1000 μs) | Withstands high-energy transients from inductive loads (e.g., solenoids, motors) without degradation |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control units and body electronics |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during clamping, reducing risk to downstream ICs and MOSFETs |
| Solderable per J-STD-002/JESD 22-B102 | Compatible with standard wave and reflow processes; matte tin plating prevents whisker growth (JESD 201 Class 1A) |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 24 V supply lines in vehicle ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and local regulator input to clamp surges above 300 V. Use Value: Limits transient voltage to ≤482 V, preventing damage to LDOs and microcontrollers rated for 40 V absolute max. | Use Scenario: Shielding digital input channels of programmable logic controllers from field-wiring induced surges (IEC 61000-4-5). IC Role / Device Role / Timing Role: Mounted at connector entry point to shunt surge energy before it reaches optocoupler or Schmitt trigger inputs. Use Value: Fast <1 ns response captures rising edge of 1.2/50 μs surges, while 600 W rating handles multi-kV coupling events. |
| Telecom Line Interface Protection | Motor Drive Gate Driver Protection |
Use Scenario: Safeguarding RS-485 transceivers on outdoor telecom nodes exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Paired with series impedance to form low-pass filter; clamps common-mode transients across A/B lines. Use Value: 300 V VWM allows normal 12 V bias operation while rejecting >333 V threats, preserving signal integrity. | Use Scenario: Protecting high-side N-channel MOSFET gate drivers in BLDC inverters from shoot-through-inducing voltage spikes. IC Role / Device Role / Timing Role: Placed between gate and source to clamp Miller-induced dv/dt spikes exceeding VGS rating. Use Value: Low clamping voltage (≤482 V) prevents unintended turn-on while maintaining gate oxide safety margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ350A | Same VWM (300 V), same VC (482 V), but SMC package (surface-mount, 7.1 × 6.2 mm) | Requires PCB redesign for SMT placement; better thermal performance (RθJA ≈ 40 °C/W) but no axial lead option | Select SMBJ350A only if board space constraints favor SMT and thermal management supports higher power density. |
| 1.5KE350A | Same electrical specs (VWM, VBR, VC, PPPM), but larger DO-201AD package (2.5 g vs. 0.432 g) | Higher IFSM (200 A vs. 100 A); suitable for higher-energy surge environments like industrial mains interfaces | Choose 1.5KE350A where legacy DO-201AD footprint exists or where 2× surge current headroom is required. |
Compared with SMBJ350A and 1.5KE350A, P6KE350A-E3/54 offers optimal balance of axial-leaded manufacturability, AEC-Q101 qualification, and cost-effective 600 W protection in compact DO-15 - ideal for new designs prioritizing automotive compliance and through-hole assembly.

FAQ
What is the breakdown voltage range for P6KE350A-E3/54?
The P6KE350A-E3/54 has a guaranteed breakdown voltage (VBR) range of 333 V to 368 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight ±5 % tolerance ensures predictable clamping behavior in overvoltage events and supports precise system-level protection design around the 300 V standoff voltage.
Is P6KE350A-E3/54 suitable for automotive applications?
Yes, P6KE350A-E3/54 is AEC-Q101 qualified (as confirmed by Vishay's HE3 suffix variants and documentation), making it suitable for automotive use cases including engine control modules, body electronics, and infotainment power supplies. Its 175 °C max junction temperature and robust DO-15 construction meet under-hood environmental demands.
What is the clamping voltage of P6KE350A-E3/54 at its rated surge current?
The P6KE350A-E3/54 clamps to a maximum of 482 V when subjected to its rated 10/1000 μs peak pulse current of 1.2 A. This VC value is measured under standardized conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does P6KE350A-E3/54 have bidirectional capability?
No, P6KE350A-E3/54 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only in reverse bias above VBR; for bidirectional protection, the equivalent part is P6KE350CA, which provides symmetrical clamping for AC or data-line applications.
What package type and lead finish does P6KE350A-E3/54 use?
P6KE350A-E3/54 uses the DO-15 (DO-204AC) axial-leaded package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. The "E3" suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, supporting reliable through-hole assembly.
