Product details
Overview
P6KE350CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It features a 350 V breakdown voltage (VBR min = 333 V, max = 368 V), 482 A peak pulse current (IPPM) under 10/1000 μs waveform, and clamps transients to ≤482 V at rated surge, protecting downstream MOSFETs and ICs in industrial motor drives and telecom power supplies.
For engineers reviewing the P6KE350CA-E3/54 datasheet, P6KE350CA-E3/54 pinout, P6KE350CA-E3/54 application, or P6KE350CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 package compatibility with legacy PCB footprints, 600 W peak pulse power rating, and AEC-Q101 qualification for automotive-grade reliability where applicable.
Technical Context
This device operates as a voltage-clamped crowbar during transient events: when reverse (or forward, in bidirectional mode) voltage exceeds its breakdown threshold, it avalanches rapidly (<1 ns response) to divert surge current away from protected circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 μA at 300 VWM).
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling reliable operation up to TJ = +175 °C. The 10/1000 μs waveform rating reflects standardized lightning/surge immunity testing per IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 333 V / 368 V - Ensures consistent avalanche initiation across production lots; guarantees clamping begins no later than 368 V under 1 mA test current. |
| VWM | 300 V - Maximum continuous working voltage; defines safe DC or RMS operating limit before leakage rises significantly. |
| IPPM | 482 A - Peak surge current it can safely shunt with 10/1000 μs waveform; determines minimum series impedance required for coordination with upstream fuses. |
| VC | 482 V - Clamped voltage at IPPM; sets absolute overvoltage ceiling seen by protected load during worst-case surge. |
| PPPM | 600 W - Peak pulse power handling; validates suitability for Level 3/4 IEC 61000-4-5 surge immunity testing. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in high-ambient environments like engine compartments or enclosed power enclosures. |
| Package | DO-15 (DO-204AC) - Industry-standard axial leaded package; compatible with automated through-hole insertion and wave soldering (275 °C, 10 s max). |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking on bidirectional variants such as P6KE350CA-E3/54. Leads are solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (unmarked) | Bidirectional conduction path | Both terminals function identically; symmetric clamping in either polarity enables single-device protection of AC-coupled or floating signal lines. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures long-term stability of VBR and low leakage drift over temperature and lifetime; critical for unattended industrial systems. |
| 600 W peak pulse power (10/1000 μs) | Validates robustness against induced lightning surges and inductive switching spikes in 48 V telecom or 24 V PLC power rails. |
| AEC-Q101 qualified (HE3 suffix variant) | Confirms reliability for automotive subsystems; P6KE350CA-E3/54 is commercial grade but shares identical die and process with qualified versions. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients; enables tighter clamping margin versus unprotected ICs rated for ≤500 V absolute maximum. |
| RoHS-compliant, JESD 201 Class 1A whisker tested | Guarantees lead finish integrity under thermal cycling; eliminates risk of tin whisker-induced short circuits in high-reliability deployments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ350CA | DO-214AA package; lower RθJA (50 °C/W); same VBR range and PPPM, but higher IPPM (510 A). | Suitable for surface-mount designs requiring higher thermal efficiency and board space reduction. | Select SMBJ350CA when migrating to SMT assembly or improving thermal headroom in compact enclosures. |
| 1.5KE350CA | Higher PPPM (1500 W); larger DO-201AD package; identical VBR/VC specs but higher IPPM (1070 A). | Used where legacy through-hole footprint allows larger case and higher surge margin is mandated (e.g., utility meter front-ends). | Choose 1.5KE350CA only if system-level surge testing requires >600 W margin and PCB layout accommodates larger body. |
Compared with SMBJ350CA and 1.5KE350CA, P6KE350CA-E3/54 offers optimal balance of proven DO-15 footprint compatibility, 600 W surge rating, and cost-effective commercial-grade reliability-making it ideal for high-volume industrial power supplies where board real estate and legacy tooling constrain design changes.

FAQ
What is the standoff voltage (VWM) of the P6KE350CA-E3/54?
The P6KE350CA-E3/54 has a maximum working voltage (VWM) of 300 V. This value represents the highest continuous DC or RMS voltage that can be applied across the device without exceeding 1.0 μA reverse leakage current. It ensures safe operation in 277 V AC-derived DC rails or 300 V nominal DC systems while preserving margin before breakdown onset at 333 V.
Is the P6KE350CA-E3/54 RoHS compliant and lead-free?
Yes, the P6KE350CA-E3/54 carries the "E3" suffix, indicating full RoHS compliance per EU Directive 2011/65/EU and exemption 7a. Its matte tin-plated leads meet JESD 201 Class 1A whisker testing requirements, and the molding compound complies with UL 94 V-0 flammability standards-ensuring environmental safety and long-term interconnect reliability.
Does the P6KE350CA-E3/54 have polarity markings on the package?
No, the P6KE350CA-E3/54 is a bidirectional TVS diode and carries no color band or other polarity marking on its DO-15 package. Both terminals are functionally identical, allowing installation in either orientation-critical for protecting AC-coupled interfaces, transformer-isolated signals, or floating bus architectures without orientation-dependent assembly errors.
What is the clamping voltage (VC) of the P6KE350CA-E3/54 at its rated peak pulse current?
The P6KE350CA-E3/54 clamps to a maximum of 482 V when subjected to its rated 482 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This VC value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and must be verified against the absolute maximum ratings of downstream components.
Can the P6KE350CA-E3/54 be used in automotive applications?
The P6KE350CA-E3/54 is commercial-grade (E3 suffix), not AEC-Q101 qualified; however, its die and process are identical to the AEC-Q101-qualified P6KE350CAHE3/54 variant. For non-safety-critical automotive subsystems-such as infotainment power rails or body control module auxiliary supplies-it may be deployed with appropriate system-level validation, though the HE3 version is required for formal qualification.
