Product details
Overview
P4KE36AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 34.2 V minimum / 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 P4KE36AHE3/54 datasheet, P4KE36AHE3/54 pinout, P4KE36AHE3/54 application, or P4KE36AHE3/54 equivalent, this AEC-Q101 qualified TVS diode is selected for automotive-grade overvoltage protection where stable clamping performance, low leakage (<1.0 μA at 30.8 V), and robust surge handling (40 A IFSM) are required.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device that remains high-impedance below its standoff voltage (VWM = 30.8 V) and rapidly transitions to low-impedance conduction above its breakdown threshold (VBR = 34.2–37.8 V). Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1.0 ns).
It delivers 400 W peak pulse power dissipation under standardized 10/1000 μs transient conditions, with thermal resistance of 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient), enabling reliable operation up to TJ = 175 °C. The matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 34.2 V min / 37.8 V max at 1 mA - defines precise clamping initiation threshold |
| Standoff Voltage (VWM) | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| Clamping Voltage (VC) | 49.9 V at 8.0 A IPPM - limits transient voltage seen by protected circuitry |
| Peak Pulse Power (PPPM) | 400 W with 10/1000 μs waveform - withstands common lightning/surge test profiles |
| Peak Forward Surge Current (IFSM) | 40 A (8.3 ms half-sine) - handles inrush and switching surges without failure |
| Junction Temperature Range | -55 °C to +175 °C - supports automotive under-hood and industrial environments |
| Leakage Current (ID) | ≤1.0 μA at VWM - ensures minimal power loss in standby or low-power systems |
Pinout & Package
Package: DO-41 (DO-204AL), molded epoxy body with glass passivated chip junction. Matte tin-plated leads; cathode indicated by color band. Complies with UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| JESD 201 Class 2 whisker resistance | HE3 suffix confirms enhanced reliability for lead-free reflow and long-term storage |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | DO-214AA package; 36 V VBR (min 32.4 V); 600 W PPPM; 100 A IPPM | Higher surge capacity but larger footprint; requires PCB layout change | Select when higher surge margin is needed and board space permits SMB footprint |
| 1.5KE36A | DO-201AD package; same VBR range; 1500 W PPPM; 41.7 A IPPM; 1.5 W PD | Higher power rating but longer lead time and less automotive qualification coverage | Choose for non-automotive industrial systems requiring extended surge endurance |
Compared with SMBJ36A and 1.5KE36A, P4KE36AHE3/54 offers AEC-Q101 qualification and DO-41 compatibility in cost-sensitive, space-constrained automotive and consumer designs where 400 W surge handling suffices.

FAQ
What is the breakdown voltage tolerance of P4KE36AHE3/54?
The P4KE36AHE3/54 has a specified breakdown voltage range of 34.2 V minimum to 37.8 V maximum at 1 mA test current, corresponding to ±5.3% tolerance around the nominal 36 V rating. This tight VBR window ensures consistent clamping behavior across production lots and temperature ranges, critical for predictable system-level surge protection design.
Is P4KE36AHE3/54 suitable for bidirectional transient suppression?
No, P4KE36AHE3/54 is a unidirectional TVS diode, intended for use in DC circuits where polarity is fixed. For bidirectional applications such as AC lines or data buses, Vishay specifies variants with "CA" suffix (e.g., P4KE36CA). Using P4KE36AHE3/54 in reverse-biased AC configurations may result in unintended conduction and failure.
What does the "HE3/54" suffix indicate in P4KE36AHE3/54?
The "HE3" suffix denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance, confirming suitability for lead-free reflow and long-term reliability in automotive environments. The "/54" indicates packaging in 13-inch paper tape and reel with 5500 units per reel, per Vishay's ordering convention.
How does P4KE36AHE3/54 perform under elevated ambient temperatures?
P4KE36AHE3/54 derates linearly above TA = 25 °C: its peak pulse power drops to ~50% at 100 °C ambient, per Figure 2 in the datasheet. Its 175 °C maximum junction temperature and 66 °C/W junction-to-lead thermal resistance allow effective heat dissipation through PCB copper when mounted with adequate pad area and lead length.
Can P4KE36AHE3/54 replace P4KE36A-E3/54 in existing designs?
Yes, P4KE36AHE3/54 is a direct replacement for P4KE36A-E3/54 with identical electrical specifications and DO-41 mechanical form factor. The HE3 variant adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, making it preferable for automotive and high-reliability applications without requiring layout or schematic changes.
