Product details
Overview
P4KE36C-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 a 34.2 V minimum and 37.8 V maximum breakdown voltage at 1 mA test current, 30.8 V standoff voltage, 49.9 V maximum clamping voltage at 8.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE36C-E3/54 datasheet, P4KE36C-E3/54 pinout, P4KE36C-E3/54 application, or P4KE36C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 through-hole compatibility, AEC-Q101 qualification status (not applicable to E3 suffix), and thermal resistance of 100 °C/W junction-to-ambient under standard lead length conditions.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with symmetrical electrical characteristics in both directions due to its bidirectional construction. It delivers 400 W peak pulse power handling per 10/1000 μs waveform and maintains stable clamping performance across -55 °C to +175 °C operating junction temperature range.
The P4KE36C-E3/54 exhibits low incremental surge resistance and fast response time typical of glass-passivated junction TVS diodes. Its 30.8 V stand-off voltage ensures reliable blocking during normal operation while allowing conduction only when transient voltages exceed the 34.2–37.8 V breakdown window.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min / max | 34.2 V / 37.8 V at 1 mA - defines precise voltage threshold for avalanche conduction onset |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VC @ IPPM | 49.9 V at 8.0 A - clamped voltage during worst-case 400 W transient, limiting downstream stress |

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; 600 W peak power; lower RθJA (50 °C/W); same VBR range | Requires PCB re-layout for SMD placement; better thermal performance in space-constrained designs | Select when board space is limited and higher surge margin is needed without changing clamping behavior |
| 1.5KE36CA | Higher peak power (1500 W); larger DO-201 package; same VBR/VC specs; higher IPPM (32.4 A) | Used where single-event surge energy exceeds 400 W, e.g., industrial motor drives or outdoor telecom cabinets | Choose for legacy through-hole designs needing enhanced single-pulse robustness without altering circuit topology |
Compared with P4KE36C-E3/54, SMBJ36CA offers superior thermal efficiency and smaller footprint but requires SMT assembly, while 1.5KE36CA provides triple the peak power in the same axial form factor-making it suitable for higher-energy threat environments without layout changes.

FAQ
What does the "C" suffix indicate in P4KE36C-E3/54?
The "C" in P4KE36C-E3/54 denotes bidirectional configuration, meaning the device provides symmetrical clamping for both positive- and negative-polarity transients. Unlike unidirectional variants (e.g., P4KE36A-E3/54), P4KE36C-E3/54 has no cathode marking and identical electrical characteristics in either direction-critical for AC-coupled or floating signal line protection where polarity is undefined.
Is P4KE36C-E3/54 AEC-Q101 qualified?
No, P4KE36C-E3/54 is not AEC-Q101 qualified. The E3 suffix indicates RoHS-compliant commercial-grade construction. For automotive-qualified versions, select the HE3 suffix variant (e.g., P4KE36CHE3/54), which undergoes additional stress testing per AEC-Q101 and carries explicit qualification documentation from Vishay.
What is the maximum clamping voltage of P4KE36C-E3/54 under surge conditions?
The maximum clamping voltage (VC) of P4KE36C-E3/54 is 49.9 V at 8.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value represents the upper limit of voltage seen by downstream circuitry during a full-rated 400 W transient event, directly determining the protection margin for connected ICs and passive components.
Can P4KE36C-E3/54 be used in place of P4KE36A-E3/54?
No-P4KE36C-E3/54 and P4KE36A-E3/54 are functionally distinct: the "C" version is bidirectional, while the "A" version is unidirectional with cathode marking. Substituting one for the other risks incorrect clamping behavior in DC-biased circuits or failure to suppress negative transients. Always verify polarity requirements and consult the schematic before replacement.
What is the thermal resistance of P4KE36C-E3/54, and how does it affect layout?
P4KE36C-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W with 10 mm lead length. This value mandates careful copper pour design around leads and limits sustained power dissipation to ~1.5 W. For repeated surge events, ensure adequate PCB copper area and avoid routing heat-sensitive components nearby to prevent thermal runaway or parameter drift.
