Product details
Overview
P6KE33CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal or power lines. It features a 33 V breakdown voltage (VBR min/max = 31.4–34.7 V), 45.7 V maximum clamping voltage at 13.1 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and DO-15 package with AEC-Q101 qualification for automotive-grade reliability. It protects MOSFETs, ICs, and sensor interfaces against inductive switching surges.
For engineers reviewing the P6KE33CA-E3/54 datasheet, P6KE33CA-E3/54 pinout, P6KE33CA-E3/54 application, or P6KE33CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, 45.7 V VC at IPPM, 1.0 μA max reverse leakage at 28.2 V VWM, thermal resistance of 20 °C/W (junction-to-lead), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamping protection element in both polarities, with symmetrical electrical characteristics across forward and reverse directions. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01% duty cycle.
The P6KE33CA-E3/54 is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, supported by RθJL = 20 °C/W and RθJA = 75 °C/W. It meets JESD22-B106 solderability (275 °C, 10 s) and JESD201 Class 1A whisker resistance per E3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V - ensures reliable conduction onset within defined tolerance at 1 mA test current |
| VWM | 28.2 V - maximum continuous working voltage before significant leakage begins |
| VC @ IPPM | 45.7 V at 13.1 A - clamped voltage during 600 W transient, defining protected circuit's worst-case overvoltage |
| IPPM | 13.1 A - peak pulse current survivable under 10/1000 μs waveform without degradation |
| PPPM | 600 W - transient energy absorption capacity critical for automotive load-dump and ESD immunity |
| RθJL | 20 °C/W - enables effective heat transfer to PCB copper or lead frame, supporting sustained surge handling |
| TJ max | 175 °C - allows operation in under-hood automotive environments and industrial enclosures |
Pinout & Package
Package: DO-15 (DO-204AC), 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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias | One end of symmetrical junction; no polarity marking on bidirectional devices |
| Cathode | Current exit point in forward bias | Opposite end of symmetrical junction; identical behavior to anode under reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 600 W peak pulse power | Supports robust immunity to ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surge events |
| AEC-Q101 qualified (HE3 variant); E3 meets commercial grade | P6KE33CA-E3/54 is RoHS-compliant commercial-grade; HE3 suffix required for automotive qualification |
| Fast response time (<1 ns) | Clamps transients before sensitive downstream components experience overstress |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes let-through voltage, reducing stress margin requirements for protected ICs |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and inductive kickback in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and ground, absorbing transients before they reach the transceiver input stage. Use Value: Limits voltage to ≤45.7 V during 13.1 A surges, preventing latch-up or gate oxide damage in 5 V/3.3 V interface ICs. | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Parallel-connected TVS on 24 V DC input terminals, shunting surge energy away from optocoupler or Schmitt trigger inputs. Use Value: Withstands repeated 600 W pulses at 0.01% duty cycle, ensuring long-term reliability in factory automation environments. |
| Consumer Power Adapter Output | Telecom Line Interface |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters to prevent damage during feedback loop failure or rectifier short. IC Role / Device Role / Timing Role: Clamping device across DC output rails (e.g., 12 V, 19 V), activated only during abnormal overvoltage conditions. Use Value: 28.2 V stand-off voltage avoids conduction during normal regulation; 45.7 V clamping prevents downstream regulator or capacitor overvoltage. | Use Scenario: Primary protection on telephone line interface circuits (e.g., SLIC, codec) against lightning-induced surges and AC power cross. IC Role / Device Role / Timing Role: First-stage surge suppressor on tip/ring lines, coordinated with GDT or MOV secondary protection. Use Value: UL 497B recognition (QVGQ2) and 600 W rating meet telecom safety and immunity requirements for central office and CPE equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | Same VBR range (31.4–34.7 V) and VC (45.7 V), but SMC package (higher IPPM = 13.9 A, lower RθJA = 35 °C/W) | Better thermal performance and higher surge margin; requires SMC footprint instead of DO-15 | Select SMBJ33CA when board space allows SMC and higher surge endurance is needed |
| 1.5KE33CA | Same DO-15 package and VBR, but higher PPPM = 1500 W and VC = 53.3 V at 28.3 A | Higher clamping voltage reduces protection margin for low-voltage ICs; suited for 24–48 V systems | Choose 1.5KE33CA only if system voltage tolerances allow ≥53 V clamping and 1500 W rating is mandatory |
Compared with SMBJ33CA and 1.5KE33CA, P6KE33CA-E3/54 offers optimal balance of DO-15 compatibility, 600 W surge rating, and 45.7 V clamping for cost-sensitive 3.3 V/5 V/12 V designs where thermal constraints preclude SMC and 1500 W is excessive.

FAQ
What is the breakdown voltage range for P6KE33CA-E3/54?
The P6KE33CA-E3/54 has a guaranteed breakdown voltage range of 31.4 V to 34.7 V at 1 mA test current (IT), measured in both directions due to its bidirectional construction. This VBR window ensures consistent clamping onset across polarity reversals and supports design margining for 28.2 V maximum working voltage (VWM). The value is confirmed in Vishay's Document Number 88369, Table on page 2.
Is P6KE33CA-E3/54 suitable for automotive applications?
P6KE33CA-E3/54 carries the E3 suffix, indicating RoHS-compliant commercial-grade qualification. For automotive use, the HE3 suffix variant (e.g., P6KE33CAHE3/54) is AEC-Q101 qualified per note (1) on page 3 of the datasheet. Engineers must specify HE3 for under-hood or safety-critical automotive deployments; P6KE33CA-E3/54 remains valid for non-automotive or non-qualified systems.
What is the maximum clamping voltage of P6KE33CA-E3/54 and at what current?
The P6KE33CA-E3/54 clamps to a maximum of 45.7 V when subjected to its rated peak pulse current of 13.1 A under the standard 10/1000 μs waveform. This VC value defines the upper voltage limit imposed on protected circuitry during surge events and is specified in the Electrical Characteristics table on page 2 of Vishay's Document Number 88369.
Does P6KE33CA-E3/54 have polarity markings on the package?
No, P6KE33CA-E3/54 does not have polarity markings because it is a bidirectional TVS diode. As stated in the "Notes" section on page 1 of the datasheet: "no marking on bidirectional types." Its symmetrical structure means either lead may be connected to line or ground without affecting clamping behavior-unlike unidirectional variants that feature a cathode band.
What is the thermal resistance and maximum junction temperature of P6KE33CA-E3/54?
P6KE33CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and a maximum junction temperature (TJ) of +175 °C, as specified in the Thermal Characteristics table on page 3 of Vishay's Document Number 88369. These values enable reliable operation in high-ambient environments when mounted with adequate copper pour or lead-frame heat sinking.
