Product details
Overview
P4KE160AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit protection against ESD and surge transients. It features 160 V breakdown voltage (VBR = 152–168 V), 136 V standoff voltage (VWM), 219 V clamping voltage at 1.8 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P4KE160AHE3/54 datasheet, P4KE160AHE3/54 pinout, P4KE160AHE3/54 application, or P4KE160AHE3/54 equivalent, key selection criteria include clamping performance under 10/1000 µs surges, unidirectional polarity with cathode band marking, DO-41 mechanical compatibility, and compliance with automotive transient immunity requirements per ISO 7637-2 and IEC 61000-4-5.
Technical Context
The P4KE160AHE3/54 operates as a silicon avalanche diode that enters controlled breakdown above its standoff voltage to clamp transient energy. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low leakage (<1 µA at 136 V), while the DO-41 package supports lead-free soldering per J-STD-002 and withstands 275 °C for 10 s.
It delivers 400 W peak pulse power with 0.01 % duty cycle, exhibits 66 °C/W junction-to-lead thermal resistance, and maintains operation from –55 °C to +175 °C. The device is rated for 40 A non-repetitive forward surge (8.3 ms half-sine) and has a temperature coefficient of 0.108 %/°C for VBR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - defines precise avalanche onset range for reliable overvoltage triggering |
| VWM | 136 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 219 V - clamped voltage during 1.8 A 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak transient power handling capability under standardized surge waveform |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | DO-214AA package, 1.5× smaller footprint, 600 W PPPM, same VBR range (152–168 V) | Higher power density; better suited for space-constrained PCB layouts but requires requalification of thermal relief pads | Select SMBJ160A when board area is limited and thermal management allows higher power density packaging. |
| 1.5KE160A | Same DO-41 package, 1500 W PPPM, identical VBR/VWM/VC specs, higher IPPM (11.3 A) | Supports heavier industrial surge events (e.g., 4 kV/2 kA IEC 61000-4-5) but draws more board copper area for heat dissipation | Choose 1.5KE160A where legacy DO-41 compatibility is required and system-level surge threat level exceeds 400 W. |
Compared with SMBJ160A and 1.5KE160A, the P4KE160AHE3/54 offers balanced surge capability and AEC-Q101 qualification in a proven DO-41 form factor-ideal for cost-sensitive automotive and industrial designs where 400 W clamping meets ISO 7637-2 Pulse 5a requirements without over-engineering.

FAQ
What is the breakdown voltage tolerance for P4KE160AHE3/54?
The P4KE160AHE3/54 has a specified breakdown voltage range of 152 V to 168 V at 1.0 mA test current, corresponding to a ±5 % tolerance around the nominal 160 V rating. This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, supporting repeatable surge protection design in automotive and industrial applications.
Is P4KE160AHE3/54 suitable for bidirectional transient protection?
No, P4KE160AHE3/54 is a unidirectional TVS diode, identified by its cathode band marking and specified VBR/VWM parameters for reverse-bias operation only. For bidirectional protection, Vishay offers the P4KE160CA variant; using P4KE160AHE3/54 in AC-coupled or symmetrical surge scenarios would require external circuitry to enforce polarity alignment.
What does the "HE3/54" suffix indicate in P4KE160AHE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; "/54" specifies packaging in 13-inch paper tape and reel with 5500 units per reel. This distinguishes it from commercial-grade "E3" variants and confirms suitability for automotive production environments requiring full process traceability.
How does P4KE160AHE3/54 perform under high ambient temperatures?
P4KE160AHE3/54 maintains rated performance up to +175 °C junction temperature, with derating applied above 25 °C ambient per Figure 2 in the datasheet. At 100 °C case temperature, its peak pulse power drops to ~260 W, and clamping voltage increases slightly due to positive VBR temperature coefficient (0.108 %/°C), requiring thermal design margin in engine compartment deployments.
Can P4KE160AHE3/54 replace P4KE150A in an existing design?
Yes, P4KE160AHE3/54 can replace P4KE150A if the system's maximum transient voltage remains below 219 V clamping level and the 136 V standoff voltage provides sufficient margin above operating rail. However, the higher VBR shifts the protection threshold upward-verify that downstream components tolerate the increased let-through voltage during surge events before substitution.
