Product details
Overview
P6KE33-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 33 V breakdown voltage (VBR = 31.4–34.7 V at IT = 1.0 mA), 45.7 V maximum clamping voltage (VC) at 13.1 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive engine control units, industrial PLC I/O modules, and telecom power supplies.
For engineers reviewing the P6KE33-E3/54 datasheet, P6KE33-E3/54 pinout, P6KE33-E3/54 application, or P6KE33-E3/54 equivalent, this device delivers verified AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin-plated leads - critical for high-reliability board-level surge immunity design.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold, it avalanches rapidly (<1 ns response) to divert surge energy away from downstream ICs. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 μA at VWM = 28.2 V).
Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, enabling reliable operation up to TJ = 175 °C. The device sustains 100 A non-repetitive forward surge (IFSM, 8.3 ms half-sine) and exhibits +0.098 %/°C temperature coefficient of VBR, supporting predictable clamping behavior across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V at IT = 1.0 mA - defines precise avalanche initiation window for repeatable clamping onset |
| VWM | 28.2 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 45.7 V at 13.1 A (10/1000 μs) - limits protected circuit voltage during worst-case surge |
| PPPM | 600 W - enables robust handling of lightning-induced or inductive-switching transients |
| IFSM | 100 A (8.3 ms half-sine) - supports survival under repetitive load-dump events in 12 V automotive systems |
| TJ max. | 175 °C - allows placement near heat-generating components without derating concerns |
| RθJL | 20 °C/W - ensures efficient heat transfer to PCB copper pour or lead frame, critical for sustained surge duty |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case meeting UL 94 V-0; matte tin-plated leads solderable per J-STD-002; cathode indicated by color band on body.

| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive under-hood applications including engine control, body electronics, and ADAS sensor interfaces |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD > 30 kV), preserving signal integrity on data lines |
| RoHS-compliant, JESD 201 Class 1A whisker tested | Enables use in lead-free reflow processes and eliminates tin whisker risk in high-reliability industrial deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A | Same VBR range (31.4–34.7 V) but SMC (DO-214AB) package; 600 W rating; lower RθJA (50 °C/W) | Better thermal performance in high-density layouts; requires larger PCB footprint than DO-15 | Select SMBJ33A when board space permits and higher thermal margin is needed for repeated surge exposure |
| 1.5KE33A | Same DO-204AC package but higher 1500 W rating; VBR = 28.2–31.4 V; VC = 49.9 V at 30 A | Higher surge capacity suits infrequent but extreme transients (e.g., AC mains coupling); less precise clamping | Choose 1.5KE33A where legacy 1.5 kW designs exist or where higher IPPM headroom is required without changing layout |
Compared with SMBJ33A and 1.5KE33A, P6KE33-E3/54 offers optimal balance of compact DO-15 footprint, AEC-Q101 qualification, and tightly controlled clamping (45.7 V), making it preferred for cost-sensitive automotive and industrial control boards where space and reliability are jointly constrained.

FAQ
What is the clamping voltage of P6KE33-E3/54 under standard test conditions?
The P6KE33-E3/54 has a maximum clamping voltage (VC) of 45.7 V when subjected to a 10/1000 μs waveform peak pulse current of 13.1 A. This value is measured per JEDEC standards and reflects the upper limit of voltage seen by protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings. The P6KE33-E3/54 achieves this with minimal overshoot due to its low incremental surge resistance.
Is P6KE33-E3/54 qualified for automotive applications?
Yes, P6KE33-E3/54 is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88369, Revision 18-Sep-12). The "E3" suffix denotes RoHS-compliant commercial grade with JESD 201 Class 1A whisker testing, while the "HE3" variant adds full AEC-Q101 qualification. Engineers deploying P6KE33-E3/54 in engine control, body electronics, or ADAS subsystems can rely on its validated performance across -55 °C to +175 °C junction temperature range.
How does the DO-204AC (DO-15) package of P6KE33-E3/54 affect thermal design?
The DO-204AC (DO-15) package of P6KE33-E3/54 provides RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), meaning effective thermal management requires adequate copper pour on the cathode/anode pads and short, wide traces. Unlike SMC-packaged alternatives, the DO-15's smaller footprint limits heat-spreading area - so P6KE33-E3/54 is best suited for applications with intermittent surges rather than continuous high-duty-cycle stress.
What is the maximum reverse leakage current for P6KE33-E3/54 at its stand-off voltage?
At its maximum stand-off voltage (VWM = 28.2 V), the P6KE33-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA at TA = 25 °C. This ultra-low leakage ensures minimal power loss in always-on circuits such as automotive battery monitoring or IoT sensor sleep modes - a key advantage over higher-leakage alternatives like Zener-based protectors.
Can P6KE33-E3/54 be used in bi-directional protection configurations?
No, P6KE33-E3/54 is a unidirectional TVS diode, identifiable by its cathode band marking. Bi-directional operation requires the "CA" suffix (e.g., P6KE33CA), which lacks polarity marking and conducts symmetrically in both directions. Using P6KE33-E3/54 in bi-directional applications would result in forward conduction during negative transients, potentially damaging the device or failing to clamp - always verify suffix and polarity before layout integration.
