Product details
Overview
P4KE36CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 34.2 V minimum and 37.8 V maximum breakdown voltage at 1.0 mA test current, 30.8 V stand-off voltage, 49.9 V maximum clamping voltage at 8.0 A peak pulse current, and 400 W peak pulse power dissipation with 10/1000 μs waveform - used to protect MOSFETs and sensor signal lines in automotive ECUs.
For engineers reviewing the P4KE36CA-E3/54 datasheet, P4KE36CA-E3/54 pinout, P4KE36CA-E3/54 application, or P4KE36CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 leaded package compatibility with through-hole PCB assembly, AEC-Q101 qualification for automotive use, and verified 175 °C maximum junction temperature handling under surge conditions.
Technical Context
This device operates as a voltage-clamped avalanche diode, responding within <1 ns to transient overvoltages and limiting reverse voltage across protected circuitry to ≤49.9 V at 8.0 A. Its bidirectional symmetry enables protection of AC-coupled or differential signal paths without polarity constraints.
The glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, while the DO-41 package supports soldering per J-STD-002 and JESD 22-B102, with matte tin-plated leads and JESD 201 Class 1A whisker resistance (E3 suffix).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA | Surface-mount SMB package; same 36 V nominal breakdown but 600 W PPPM rating | Requires rework of PCB layout; better suited for space-constrained designs with higher surge margin | Select when board real estate is limited and surge immunity beyond 400 W is required |
| 1.5KE36CA | Higher 1500 W PPPM rating in DO-201 package; identical VBR and VC specs | Larger DO-201 footprint; higher thermal mass supports more frequent surge events | Select for industrial power supplies where surge repetition rate exceeds 0.01 % duty cycle |

FAQ
What is the clamping voltage of P4KE36CA-E3/54 at its rated peak pulse current?
The P4KE36CA-E3/54 has a maximum clamping voltage (VC) of 49.9 V at 8.0 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value ensures downstream 3.3 V or 5 V logic components remain within safe operating voltage margins during surge events. The clamping performance is guaranteed across the full operating temperature range of –55 °C to +175 °C.
Is P4KE36CA-E3/54 suitable for automotive applications?
Yes, P4KE36CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junctions, matte tin-plated leads compliant with J-STD-002, and operation up to +175 °C junction temperature - meeting requirements for engine control units, body electronics, and ADAS sensor interfaces. The E3 suffix confirms JESD 201 Class 1A whisker resistance.
How does the bidirectional design of P4KE36CA-E3/54 affect circuit implementation?
The bidirectional design of P4KE36CA-E3/54 means both terminals are functionally identical with no cathode marking - enabling placement in AC-coupled, differential, or polarity-agnostic signal paths without orientation concerns. This simplifies PCB layout and eliminates risk of reverse installation, unlike unidirectional TVS diodes which require strict anode/cathode alignment relative to ground.
What is the maximum steady-state power dissipation of P4KE36CA-E3/54?
P4KE36CA-E3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. In typical through-hole applications with 10 mm lead length, thermal resistance is 100 °C/W junction-to-ambient, so derating is required above 25 °C ambient to maintain safe junction temperature below 175 °C.
Does P4KE36CA-E3/54 have RoHS compliance documentation?
Yes, P4KE36CA-E3/54 carries the E3 suffix, indicating full RoHS compliance per Directive 2011/65/EU and material categorization per Vishay document 99912. The DO-41 package uses lead-free matte tin plating and UL 94 V-0 compliant epoxy molding compound - verified in Vishay's official declaration of conformity and available upon request from Aetrix Electronics.
