Product details
Overview
P4KE160HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 136 V stand-off voltage (VWM), 152–168 V breakdown voltage (VBR) at 1 mA, 400 W peak pulse power (10/1000 μs), and clamps transients to ≤219 V at 1.8 A peak pulse current - deployed in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE160HE3/54 datasheet, P4KE160HE3/54 pinout, P4KE160HE3/54 application, or P4KE160HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low incremental surge resistance, and compatibility with lead-free reflow and wave soldering per J-STD-002.
Technical Context
The P4KE160HE3/54 operates as a silicon avalanche diode, leveraging glass-passivated junction technology to achieve fast response (<1 ns) and stable clamping under repetitive transient stress. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
Rated for 400 W peak pulse power (10/1000 μs waveform, 0.01% duty cycle), it sustains 1.5 W steady-state power dissipation on an infinite heatsink at 75 °C lead temperature and handles up to 40 A non-repetitive forward surge (8.3 ms half-sine). Thermal resistance is 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient, LLead = 10 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC bias margin. |
| VBR (min/max) | 152 V / 168 V at 1 mA - guaranteed avalanche onset range; ensures predictable clamping initiation across temperature and lot. |
| VC @ IPPM | ≤219 V at 1.8 A - maximum clamped voltage during 10/1000 μs transient; determines protected circuit's worst-case overvoltage exposure. |
| PPPM | 400 W - peak transient energy handling capacity; supports protection against ISO 7637-2 Pulse 1/2a/5a in automotive systems. |
| TJ max | +175 °C - maximum junction temperature; enables operation in under-hood automotive environments and high-ambient industrial enclosures. |
| RθJL | 66 °C/W - thermal resistance from junction to lead; informs heatsinking requirements when mounted on PCB copper pour or chassis. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per AEC specification. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body end. Leads are solderable per J-STD-002 and JESD 22-B102; compliant with JESD 201 Class 2 whisker test (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / low-impedance return during clamping | Connected to system ground or low-side reference; carries full transient current during reverse-biased clamping event. |
| Cathode | Protected line connection / high-impedance input during normal operation | Connected to line being protected (e.g., 12 V rail); blocks reverse current until VBR is exceeded, then avalanches to clamp. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, low-leakage performance over lifetime and temperature; eliminates need for hermetic sealing in cost-sensitive applications. |
| 400 W peak pulse power (10/1000 μs) | Supports immunity to severe transients like load dump (ISO 16750-2) and inductive switching spikes in 12 V/24 V systems. |
| AEC-Q101 qualified | Validated for automotive electronics use without additional qualification effort; includes extended temperature cycling and humidity testing. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD, lightning-induced surges), improving protection margin for downstream ICs. |
| RoHS-compliant, HE3 suffix | Meets global environmental regulations and JESD 201 Class 2 whisker resistance - suitable for high-reliability industrial and automotive production. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line 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 |
|---|---|---|---|
| SMBJ160A | Same VWM (136 V) and VBR range, but SMC (DO-214AB) package; 600 W PPPM, higher IPPM (3.3 A), lower RθJA (50 °C/W). | Better suited for higher-energy transients and forced-air-cooled designs; requires larger PCB footprint than DO-41. | Select SMBJ160A when >400 W pulse handling or improved thermal performance is required; not drop-in due to different package and pin spacing. |
| 1.5KE160A | Same DO-41 package and VBR spec, but 1500 W PPPM; higher IPPM (11.3 A), same VC (219 V), higher VF (5.0 V). | Targets heavy-duty industrial motor drives and generator excitation circuits with extreme surge exposure. | Choose 1.5KE160A only when system-level testing confirms need for >400 W capability; identical mounting but higher cost and larger junction capacitance. |
Compared with SMBJ160A and 1.5KE160A, the P4KE160HE3/54 offers optimal balance of AEC-Q101 qualification, compact DO-41 fit, and sufficient 400 W rating for standard automotive and industrial transients - making it preferred for space-constrained, high-volume OEM designs where qualification traceability is mandatory.

FAQ
What is the clamping voltage of the P4KE160HE3/54 under maximum rated transient conditions?
The P4KE160HE3/54 has a maximum clamping voltage (VC) of 219 V at its rated peak pulse current (IPPM) of 1.8 A, measured using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events. The P4KE160HE3/54 maintains this clamping performance consistently due to its glass-passivated avalanche junction structure.
Is the P4KE160HE3/54 suitable for automotive applications?
Yes, the P4KE160HE3/54 is explicitly AEC-Q101 qualified, with test evidence covering high-temperature operating life, temperature cycling, unbiased highly accelerated stress testing, and ESD per HBM and CDM models. Its DO-41 package, 175 °C maximum junction temperature, and stable VBR drift (0.108 %/°C) make it appropriate for under-hood and cabin ECU power rail protection. The P4KE160HE3/54 meets automotive OEM requirements for long-term reliability without additional qualification.
How does the HE3 suffix differ from the E3 suffix in P4KE160HE3/54?
The HE3 suffix on P4KE160HE3/54 indicates AEC-Q101 qualification and compliance with JESD 201 Class 2 whisker resistance testing, whereas the E3 suffix denotes commercial-grade RoHS compliance only (JESD 201 Class 1A). Both share the same DO-41 package, electrical specs, and matte tin plating, but HE3 parts undergo additional stress screening and lot-level validation for automotive use. The P4KE160HE3/54 is therefore designated for mission-critical automotive deployments where process consistency and failure mode coverage are mandated.
What is the thermal resistance of the P4KE160HE3/54, and how does it affect PCB layout?
The P4KE160HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient resistance (RθJA) of 100 °C/W with 10 mm lead length. For reliable operation above 1.5 W steady-state dissipation, PCB layout must maximize copper area connected to both leads - especially the cathode - to emulate an infinite heatsink. The P4KE160HE3/54 benefits from thermal vias under pads and ≥2 oz copper to maintain TJ < 175 °C during repetitive transient events.
Can the P4KE160HE3/54 be used in bidirectional configurations?
No - the P4KE160HE3/54 is a unidirectional TVS diode, identified by its cathode band marking and specified VBR/VWM values for reverse-bias operation only. For bidirectional protection, Vishay offers the P4KE160CA variant (with CA suffix), which provides symmetrical clamping in both polarities. Using the P4KE160HE3/54 in AC or floating signal paths without proper DC biasing will result in unintended forward conduction and potential failure. Always verify polarity alignment before integrating the P4KE160HE3/54.
