Product details
Overview
P6KE30C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for circuit-level ESD and surge protection on signal, power, and interface lines. It features a 30 V breakdown voltage (VBR min/max = 28.5–31.5 V), 25.6 V stand-off voltage (VWM), 41.4 V clamping voltage (VC) at 14.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6KE30C-E3/54 datasheet, P6KE30C-E3/54 pinout, P6KE30C-E3/54 application, or P6KE30C-E3/54 equivalent, key selection criteria include bi-directional clamping symmetry, DO-15 package thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and compliance with UL 497B surge protector classification.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical electrical characteristics (VBR, VC, IPPM) in forward and reverse directions. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance, critical for suppressing fast-rising transients from inductive switching or ESD events.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2. Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting reliable operation under repetitive surge conditions when mounted on minimum copper land patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA test current - defines precise voltage threshold where clamping begins in both directions |
| VWM | 25.6 V - maximum continuous working voltage before leakage exceeds 1.0 μA; sets safe operating margin below breakdown |
| VC @ IPPM | 41.4 V at 14.5 A peak pulse current (10/1000 μs) - limits transient voltage seen by downstream ICs to ≤41.4 V |
| PPPM | 600 W - peak surge power handling capability under standardized 10/1000 μs waveform, enabling robust protection against lightning-induced surges |
| IPPM | 14.5 A - maximum non-repetitive surge current the device can clamp without failure, validated per Fig. 3 waveform |
| TJ max. | 175 °C - maximum junction temperature rating supports operation in under-hood automotive environments and industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.300" lead spacing, UL 94 V-0 molded epoxy body |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body with matte tin-plated leads solderable per J-STD-002; no polarity marking for bi-directional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional transient conduction path | No functional distinction - terminals are interchangeable; clamps voltage excursions above ±41.4 V in either polarity |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables sub-1 ns response time and stable VBR over lifetime, critical for ESD immunity per IEC 61000-4-2 |
| 600 W peak pulse power (10/1000 μs) | Supports protection against severe transients including ISO 7637-2 Pulse 1/2a/5a in automotive 12 V systems |
| AEC-Q101 qualified (HE3 suffix variant) | P6KE30C-E3/54 is commercial grade; HE3 variant meets automotive reliability stress testing for engine control and body electronics |
| UL 497B recognized (QVGQ2 file E136766) | Validated for use as primary telecom/data line protector in safety-critical infrastructure applications |
| Low clamping ratio (VC/VBR ≈ 1.41) | Minimizes let-through voltage during surge events, reducing stress on protected MOSFETs and microcontrollers |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and inductive kickback in vehicle ECUs.

IC Role / Device Role / Timing Role: Primary surge suppression element mounted at connector entry point, shunting >14 A transients to ground. Use Value: Maintains signal integrity by limiting input voltage excursion to ≤41.4 V, avoiding ADC saturation or op-amp rail-to-rail clipping. |
| Telecom Line Interface Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Shielding Ethernet PHYs, RS-485 transceivers, and DSL line drivers from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), clamping residual energy after GDT fires. Use Value: UL 497B recognition ensures compliance with telecom safety standards while delivering <1 ns response to fast-rising transients. |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Parallel-connected across motor terminals to clamp inductive turn-off spikes before they reach driver FETs. Use Value: Extends MOSFET lifetime by limiting drain-source voltage to ≤41.4 V during commutation, preventing avalanche overstress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | DO-214AA package; 33 V VBR; 52.5 V VC @ 11.3 A; lower power density (600 W same, but smaller thermal mass) | Better suited for PCB space-constrained designs; higher VC/VBR ratio reduces clamping margin | Select SMBJ33CA when board real estate is limited and thermal management via heatsinking is impractical. |
| 1.5KE33CA | DO-201AD package; same VBR/VC specs; 1.5 kW peak power rating; larger footprint and higher IPPM (38.2 A) | Higher surge endurance for infrequent but extreme transients (e.g., AC mains coupling); less suitable for high-density layouts | Choose 1.5KE33CA for mission-critical industrial equipment requiring extended surge lifetime beyond 1000 pulses. |
Compared with P6KE30C-E3/54, SMBJ33CA offers surface-mount compatibility at the cost of reduced thermal robustness, while 1.5KE33CA delivers superior single-pulse energy handling in a through-hole package requiring more board area.

FAQ
What is the polarity configuration of P6KE30C-E3/54?
P6KE30C-E3/54 is a bi-directional TVS diode with symmetrical clamping behavior in both polarities. Unlike uni-directional variants (e.g., P6KE30A), it has no cathode marking and functions identically regardless of terminal orientation - making it ideal for AC-coupled or differential signal lines where polarity reversal is possible.
Does P6KE30C-E3/54 meet AEC-Q101 qualification?
P6KE30C-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial-grade construction. The AEC-Q101 qualified version is designated P6KE30CHE3/54 (HE3 suffix). While P6KE30C-E3/54 shares identical electrical specs, only the HE3 variant undergoes full automotive stress testing per AEC-Q101 Rev D.
What is the maximum clamping voltage of P6KE30C-E3/54 under surge conditions?
The maximum clamping voltage of P6KE30C-E3/54 is 41.4 V, measured at 14.5 A peak pulse current using the standardized 10/1000 μs waveform. This value represents the upper limit of voltage imposed on protected circuitry during worst-case transient events, ensuring downstream 3.3 V or 5 V ICs remain within safe operating limits.
Can P6KE30C-E3/54 be used in place of P6KE30A?
P6KE30C-E3/54 replaces P6KE30A only in bi-directional applications. P6KE30A is uni-directional (cathode-banded) with asymmetric forward conduction; substituting it with P6KE30C-E3/54 in DC-biased circuits may cause unintended forward conduction. Always verify signal polarity and grounding topology before interchange.
What is the thermal resistance specification for P6KE30C-E3/54?
P6KE30C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W. These values assume standard DO-15 mounting with 0.375" lead length; actual thermal performance improves with copper pour and thermal vias under the leads.
