Product details
Overview
P6KE350C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 333 V minimum breakdown voltage (VBR), 300 V stand-off voltage (VWM), 482 A peak pulse current (IPPM), and 482 V maximum clamping voltage (VC) at IPPM, with 600 W peak pulse power rating under 10/1000 μs waveform - used to protect automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the P6KE350C-E3/54 datasheet, P6KE350C-E3/54 pinout, P6KE350C-E3/54 application, or P6KE350C-E3/54 equivalent, key selection criteria include bi-directional clamping capability, UL 497B recognition, AEC-Q101 qualification (via HE3 variant), DO-15 mechanical compatibility, and thermal resistance (RθJL = 20 °C/W) for board-level surge robustness.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM = 300 V, it avalanches into low-impedance conduction, limiting downstream voltage to ≤482 V at 482 A. Its glass-passivated junction enables fast response (<1 ns) and stable breakdown characteristics across -55 °C to +175 °C operating range.
Designed for repetitive surge immunity, it supports 0.01 % duty cycle at 600 W with derating above 25 °C ambient (per Fig. 2), and withstands 100 A non-repetitive forward surge (8.3 ms half-sine) in uni-directional variants - though P6KE350C-E3/54 is bi-directional and thus has no polarity marking or VF specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 300 V - maximum continuous reverse working voltage before clamping initiates |
| VBR (min/max) | 333 V / 368 V at 1 mA - ensures reliable avalanche turn-on within defined tolerance band |
| VC @ IPPM | 482 V - clamped voltage seen by protected circuit during 482 A transient event |
| IPPM | 482 A - peak surge current handled under standard 10/1000 μs waveform |
| PPPM | 600 W - transient energy absorption capacity without failure |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-temperature industrial environments |
| RθJL | 20 °C/W - low thermal resistance from junction to lead supports effective heat dissipation through PCB traces |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Bi-directional construction means no cathode marking - both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Bi-directional conduction allows clamping of positive and negative transients without polarity concern |
| Lead 1 / Lead 2 | Thermal and electrical interface | Leads serve as primary heat transfer path to PCB; RθJL = 20 °C/W enables thermal design with minimal copper area |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5 %) and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Supports protection of 24 V industrial buses and 12 V automotive CAN/LIN lines against ISO 7637-2 Pulse 1/2/5a |
| UL 497B recognized (QVGQ2) | Validates suitability for telecom and industrial signal line protection per safety-critical infrastructure requirements |
| AEC-Q101 qualified (HE3 variant) | Confirms robustness for automotive applications including engine control modules and body electronics |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD ±15 kV contact discharge) |
Applications
| Automotive Sensor Interfaces | Industrial PLC Analog Inputs |
|---|---|
Use Scenario: Protecting temperature, pressure, and position sensors connected to microcontrollers in engine bays or chassis modules. IC Role / Device Role / Timing Role: Shunt clamping element placed between signal line and ground to divert ESD and load-dump energy away from precision ADC inputs. Use Value: Maintains signal integrity by limiting transient voltage to ≤482 V while surviving repeated 10/1000 μs surges up to 600 W - critical for ASIL-B functional safety compliance. |
Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers exposed to relay coil kickback and motor drive noise. IC Role / Device Role / Timing Role: Bidirectional overvoltage clamp on differential input stage, referenced to system ground with no polarity dependency. Use Value: Enables uninterrupted operation during 4 kV EFT bursts (IEC 61000-4-4) due to sub-nanosecond response and low clamping ratio (VC/VBR ≈ 1.45). |
| Telecom Line Cards | Consumer Appliance Motor Controls |
Use Scenario: Shielding Ethernet PHY interfaces and RS-485 transceivers in network edge devices from lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end TVS on data lines, coordinated with GDT or MOV secondary protection stages. Use Value: UL 497B recognition permits use in certified telecom equipment; 300 V VWM avoids false triggering on 24 V PoE signaling voltages. |
Use Scenario: Suppressing commutation spikes from universal motor brushes in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Across-the-line clamp on AC mains input to suppress >1 kV transients generated by brush arcing. Use Value: Withstands 100 A surge current (IFSM-equivalent stress) and maintains clamping below 500 V - preventing triac/driver IC latch-up or gate oxide damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ350CA | DO-214AA package; lower IPPM (322 A); same VWM/VC specs but higher RθJA (65 °C/W) | Better suited for surface-mount layouts with space constraints; less effective in high-ambient thermal environments | Select SMBJ350CA only if board real estate prohibits axial DO-15 placement and thermal margin ≥25 °C exists. |
| 1.5KE350CA | Same DO-204AC package; higher PPPM (1500 W); larger junction capacitance (≈200 pF vs. ~50 pF) | Preferred for high-energy lightning surge zones (e.g., AC mains entry); unsuitable for high-speed data lines due to capacitance | Choose 1.5KE350CA where IEC 61000-4-5 Level 4 (4 kV) immunity is required and signal bandwidth <1 MHz. |
Compared with SMBJ350CA and 1.5KE350CA, P6KE350C-E3/54 delivers optimal balance of axial-package manufacturability, 600 W surge handling, low clamping voltage, and proven AEC-Q101 qualification path - making it ideal for cost-sensitive automotive and industrial designs requiring field-proven reliability.

FAQ
What is the polarity configuration of P6KE350C-E3/54?
P6KE350C-E3/54 is a bi-directional TVS diode, meaning it provides symmetrical clamping for both positive and negative voltage transients. Unlike uni-directional variants (e.g., P6KE350A), it has no cathode band marking and functions identically regardless of terminal orientation - essential for protecting AC-coupled or differential signal paths where polarity is undefined.
Does P6KE350C-E3/54 meet AEC-Q101 qualification?
The base P6KE350C-E3/54 is RoHS-compliant and rated for commercial temperature range (-55 °C to +175 °C), but AEC-Q101 qualification applies specifically to the HE3 suffix variant (e.g., P6KE350CHE3/54). Engineers requiring automotive-grade validation must specify the HE3 version, which undergoes additional stress testing per AEC-Q101 Rev D.
What is the maximum clamping voltage of P6KE350C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE350C-E3/54 is 482 V when subjected to its rated peak pulse current of 482 A under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events.
Can P6KE350C-E3/54 be used in place of P6KE350A?
No - P6KE350C-E3/54 and P6KE350A are functionally distinct: the "C" suffix denotes bi-directional operation, while "A" indicates uni-directional. Substituting one for the other risks improper clamping on reverse-polarity transients or unintended forward conduction. Always match suffix type to circuit topology: use P6KE350C-E3/54 only where bidirectional protection is required.
What packaging format is supplied for P6KE350C-E3/54?
P6KE350C-E3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 4000 units per reel (package code "54"). The "E3" suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, supporting lead-free reflow and wave soldering processes per industry standards.
