Product details
Overview
P4KE160CAHE3/54 from Vishay General Semiconductor is a bidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 160 V breakdown voltage (VBR min/max = 152–168 V), 136 V stand-off voltage (VWM), 219 V maximum clamping voltage (VC) at 1.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the P4KE160CAHE3/54 datasheet, P4KE160CAHE3/54 pinout, P4KE160CAHE3/54 application, or P4KE160CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), and junction temperature range (−55 °C to +175 °C).
Technical Context
This device operates as a voltage-clamped surge protector using an avalanche breakdown mechanism. Its bidirectional symmetry enables suppression of both positive and negative transients without polarity sensitivity, making it suitable for AC-coupled or floating signal paths. The glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM).
It delivers 400 W peak pulse power handling per 10/1000 µs waveform with 0.01 % duty cycle, and exhibits fast response time (<1.0 ns) due to its PN-junction structure. Thermal performance is defined by RθJL = 66 °C/W and RθJA = 100 °C/W (lead length = 10 mm), supporting reliable operation under repetitive surge conditions when mounted on standard PCB traces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - defines guaranteed avalanche conduction onset range under 1.0 mA test current |
| VWM | 136 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 219 V at 1.8 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak transient power absorption capability without failure |
| IFSM | Not applicable - bidirectional type has no forward surge rating |
| TJ range | −55 °C to +175 °C - supports under-hood automotive and industrial ambient environments |
| RθJL | 66 °C/W - junction-to-lead thermal resistance determines safe power derating on PCB |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160CA | Surface-mount SMB package; same VBR (152–168 V), lower PPPM (600 W), higher IPPM (32.4 A) | Requires PCB re-layout; better suited for high-density consumer electronics | Select SMBJ160CA when space-constrained SMT design and higher surge margin are prioritized over through-hole serviceability |
| 1.5KE160CA | Higher PPPM (1500 W), same DO-41 package, wider VBR tolerance (152–179 V), higher VC (259 V) | Used where higher single-event energy must be absorbed, e.g., industrial motor drives | Choose 1.5KE160CA only if system-level testing confirms need for >400 W clamping; otherwise P4KE160CAHE3/54 offers tighter VC and lower cost |
Compared with SMBJ160CA and 1.5KE160CA, P4KE160CAHE3/54 provides optimal balance of AEC-Q101 qualification, precise 219 V clamping, and through-hole manufacturability - making it preferred for automotive and industrial designs requiring proven reliability and legacy assembly compatibility.

FAQ
What is the clamping voltage of P4KE160CAHE3/54 and how does it affect circuit protection?
The P4KE160CAHE3/54 has a maximum clamping voltage (VC) of 219 V at 1.8 A peak pulse current (10/1000 µs waveform). This value defines the highest voltage that will appear across protected circuitry during a surge event. Because VC is significantly lower than typical IC absolute maximum ratings (e.g., 36 V for many microcontrollers), the P4KE160CAHE3/54 effectively limits transient energy transfer and prevents latch-up or permanent damage to downstream components.
Is P4KE160CAHE3/54 suitable for automotive applications?
Yes, P4KE160CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its −55 °C to +175 °C operating junction temperature range, glass-passivated junction stability, and DO-41 mechanical robustness meet requirements for engine control units, body electronics, and ADAS sensor interfaces. The HE3 suffix confirms AEC-Q101 compliance per Vishay's ordering nomenclature.
Does P4KE160CAHE3/54 have polarity markings, and how is it installed?
No, P4KE160CAHE3/54 has no polarity markings because it is a bidirectional TVS diode. Both leads are functionally identical - installation requires no orientation check. This simplifies assembly and eliminates risk of reverse installation errors in production, especially in high-volume automotive harness or module manufacturing where polarity-sensitive components increase test complexity.
What is the thermal resistance of P4KE160CAHE3/54 and why does it matter?
P4KE160CAHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. This parameter determines how efficiently heat generated during surge events transfers from the silicon junction to the PCB copper or heatsink. Lower RθJL enables higher sustained power dissipation and improves reliability under repetitive surge conditions - critical in industrial controls where transients occur frequently.
How does P4KE160CAHE3/54 differ from unidirectional P4KE160A variants?
P4KE160CAHE3/54 is bidirectional with symmetrical clamping in both polarities and no cathode band; P4KE160A is unidirectional with a cathode marking and forward voltage drop (~5.0 V). The CA version is used on AC lines or floating signals (e.g., RS-485), while the A version suits DC rail protection where polarity is fixed. Their VBR, VWM, and VC values are identical, but P4KE160A also specifies IFSM = 40 A - irrelevant for the CA variant.
