Product details
Overview
P4KE160-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level overvoltage protection. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR at 1 mA), 219 V maximum clamping voltage at 1.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and signal lines of automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE160-E3/54 datasheet, P4KE160-E3/54 pinout, P4KE160-E3/54 application, or P4KE160-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJL = 66 °C/W), AEC-Q101 qualification status, and DO-41 lead-form compatibility with legacy through-hole PCB layouts.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches to divert surge current away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at 136 V).
It sustains 400 W peak pulse power under standardized 10/1000 μs waveform with 0.01% duty cycle, and handles up to 40 A non-repetitive forward surge (8.3 ms half-sine). Thermal performance is defined by RθJL = 66 °C/W and maximum junction temperature of +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - maximum continuous reverse operating voltage before conduction begins; sets upper limit for normal circuit operation |
| VBR (min/max) | 152 V / 168 V at 1 mA - precise avalanche onset range defining protection threshold tolerance |
| VC @ IPPM | 219 V at 1.8 A - clamping voltage during 10/1000 μs surge; determines stress on protected device |
| PPPM | 400 W - peak transient power handling capacity; defines survivability against lightning or ESD-like events |
| IFSM | 40 A - non-repetitive forward surge rating (8.3 ms); supports inrush or load-dump immunity in automotive power systems |
| TJ max. | +175 °C - maximum junction temperature; enables operation in under-hood or high-ambient industrial environments |
| RθJL | 66 °C/W - thermal resistance junction-to-lead; informs heatsinking requirements for sustained pulse repetition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | Surface-mount SMB package (vs. through-hole DO-41); same VWM/VBR specs; 600 W PPPM; higher IPPM (3.3 A) | Requires PCB redesign for SMT placement; better suited for space-constrained consumer electronics | Select SMBJ160A when board real estate is limited and automated assembly is preferred; verify thermal pad layout for RθJA = 40 °C/W. |
| 1.5KE160A | Same DO-41 package; higher PPPM = 1500 W; VC = 259 V at 5.8 A; larger junction capacitance | Used where higher energy surges occur (e.g., industrial motor drives); less suitable for fast-edge signal lines due to higher CJ | Choose 1.5KE160A for heavy-duty industrial power inputs needing >1 kW surge margin; avoid in high-speed data lines. |
Compared with SMBJ160A and 1.5KE160A, the P4KE160-E3/54 offers optimal balance of proven through-hole reliability, AEC-Q101 readiness (via HE3 variant), and precise clamping (219 V) for cost-sensitive automotive and industrial designs where layout change is constrained.

FAQ
What is the clamping voltage of P4KE160-E3/54 and how does it protect downstream components?
The P4KE160-E3/54 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 imposed on the protected circuit during a surge event. By limiting transient voltage to ≤219 V, the P4KE160-E3/54 ensures that downstream components - such as 200 V-rated MOSFETs or 250 V-input DC/DC converters - remain within their absolute maximum ratings, preventing catastrophic failure or parametric shift. Its fast response time (<1 ns) enables effective suppression before sensitive nodes experience overstress.
Is P4KE160-E3/54 AEC-Q101 qualified?
The P4KE160-E3/54 itself is the commercial-grade variant (E3 suffix) and is not AEC-Q101 qualified. However, the functionally identical P4KE160AHE3/54 - distinguished by the "HE3" suffix - is fully AEC-Q101 qualified and shares identical electrical specifications, DO-41 packaging, and thermal characteristics. For automotive applications requiring qualification evidence, P4KE160AHE3/54 must be specified; both variants use the same die and manufacturing process, differing only in test screening and traceability documentation.
What is the standoff voltage (VWM) of P4KE160-E3/54 and why does it matter?
The standoff voltage (VWM) of P4KE160-E3/54 is 136 V - the maximum continuous reverse voltage the device can block without significant leakage current (<1.0 μA). This parameter is critical for ensuring the TVS remains non-conductive during normal operation while still providing sufficient margin above system operating voltage (e.g., 12 V or 24 V rails with ripple). Selecting VWM too close to nominal voltage risks false triggering; 136 V provides safe headroom for 120 VAC-derived supplies or 100 V DC bus systems, avoiding unnecessary power loss or thermal stress.
Can P4KE160-E3/54 be used in bidirectional configurations?
No - P4KE160-E3/54 is a unidirectional TVS diode, identified by its cathode band marking and specified VBR/VC values for reverse-biased operation only. Bidirectional protection requires the CA-suffixed variant (e.g., P4KE160CA), which contains two opposing diodes in series and exhibits symmetrical clamping in both polarities. Using P4KE160-E3/54 in a bidirectional application would result in forward conduction and potential failure during negative transients; always match suffix (A vs. CA) to polarity requirement.
What is the thermal resistance and maximum junction temperature of P4KE160-E3/54?
The P4KE160-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and a maximum junction temperature (TJ) of +175 °C. These parameters define its ability to dissipate heat during repetitive surge events. With RθJL = 66 °C/W, a 1 W average power dissipation raises junction temperature by 66 °C above lead temperature - making lead soldering quality and copper pour area critical for thermal management. The +175 °C TJ max enables reliable operation in under-hood automotive or high-ambient industrial enclosures where ambient temperatures exceed +105 °C.
