Product details
Overview
P4KE160CHE3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-41 package, rated for 160 V breakdown voltage (VBR = 152–168 V at IT = 1.0 mA), 400 W peak pulse power (10/1000 µs), and clamping voltage of 219 V at 1.8 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in automotive power supplies and industrial sensor interfaces.
For engineers reviewing the P4KE160CHE3/73 datasheet, P4KE160CHE3/73 pinout, P4KE160CHE3/73 application, or P4KE160CHE3/73 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, DO-41 mechanical data, and real-world protection use cases - all aligned to Vishay Document #88365 Rev. 16-Sep-2021.
Technical Context
This device operates as a unidirectional avalanche diode with glass-passivated junction, designed to clamp transient overvoltages before they damage downstream circuitry. Its 10/1000 µs waveform response enables reliable suppression of inductive kickback and ESD-like surges without thermal runaway.
Rated for -55 °C to +175 °C junction temperature, it features 66 °C/W junction-to-lead thermal resistance and meets JESD 22-B106 solderability (275 °C, 10 s). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V at 1.0 mA test current - defines precise avalanche initiation threshold for predictable clamping onset |
| VWM | 136 V - maximum continuous reverse working voltage; ensures no conduction during normal operation |
| VC @ IPPM | 219 V at 1.8 A - clamped voltage under 400 W surge; limits stress on protected ICs below safe operating limits |
| IPPM | 1.8 A - peak pulse current capability with 10/1000 µs waveform; validates robustness against common automotive load-dump events |
| PPPM | 400 W - standardized surge power rating; enables direct comparison with competing TVS devices under identical test conditions |
| TJ max. | +175 °C - high-temperature operation support for under-hood automotive and industrial environments |
| RθJL | 66 °C/W - low junction-to-lead thermal resistance; allows effective heat dissipation through PCB traces or heatsinking leads |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body; lead length ≥ 10 mm for thermal derating compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or low-side return path; conducts during forward surge events (e.g., reverse polarity protection) |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 12 V rail); initiates breakdown when reverse voltage exceeds VBR, shunting surge current to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics over lifetime and temperature; eliminates surface leakage paths |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control units and body electronics per stress-test requirements |
| 400 W peak pulse power (10/1000 µs) | Meets ISO 7637-2 Pulse 1/2a/5a immunity levels for 12 V systems without external heat sinking |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients; improves clamping precision for sensitive logic-level interfaces |
| UL 94 V-0 compliant molding compound | Ensures flame-retardant enclosure integrity in enclosed industrial enclosures and automotive junction boxes |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|

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 | DO-214AA package; 1.5× smaller footprint; 6.5 A IPPM at same VC; higher capacitance (150 pF vs. <50 pF) | Better suited for space-constrained PCBs but less ideal for high-frequency signal lines due to higher junction capacitance | Select SMBJ160A when board area is critical and signal bandwidth <1 MHz; verify layout thermal relief for 1.5 W steady-state dissipation |
| 1N6277A | Same DO-41 package; identical VBR range and PPPM; not AEC-Q101 qualified; commercial-grade only (E3 suffix) | Limited to non-automotive industrial and consumer applications where qualification traceability is not mandated | Choose 1N6277A for cost-sensitive designs outside automotive; confirm lifecycle continuity separately as it lacks HE3 reliability testing |
Compared with P4KE160CHE3/73, SMBJ160A offers higher surge current handling in a smaller package but trades off signal integrity at high frequencies, while 1N6277A provides identical electrical performance without automotive qualification - making P4KE160CHE3/73 the sole choice when AEC-Q101 compliance and DO-41 legacy compatibility are mandatory.

FAQ
What is the clamping voltage of P4KE160CHE3/73 and how is it measured?
The clamping voltage (VC) of P4KE160CHE3/73 is 219 V, measured at 1.8 A peak pulse current using a 10/1000 µs waveform per Figure 1 in Vishay Document #88365. This value represents the maximum voltage seen across the device during a standardized surge event and directly determines the protection level afforded to downstream components. Engineers must compare this VC against the absolute maximum ratings of protected ICs to ensure margin.
Is P4KE160CHE3/73 suitable for automotive applications?
Yes, P4KE160CHE3/73 is explicitly AEC-Q101 qualified (confirmed by HE3 suffix), tested for temperature cycling, humidity bias, and mechanical shock per automotive reliability standards. Its -55 °C to +175 °C operating range, 66 °C/W thermal resistance, and DO-41 mechanical robustness make it appropriate for under-hood and chassis-mounted applications such as body control modules and power distribution units.
How does the HE3 suffix differ from E3 in P4KE160CHE3/73?
The HE3 suffix in P4KE160CHE3/73 indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS-compliant commercial grade only. HE3 parts undergo additional stress testing including HTRB, HTSL, and temperature cycling to validate automotive suitability. Both share identical electrical specs and DO-41 packaging, but HE3 is required for OEM automotive BOMs.
What is the maximum reverse leakage current for P4KE160CHE3/73 at its working voltage?
At its maximum stand-off voltage (VWM = 136 V), P4KE160CHE3/73 exhibits ≤1.0 µA reverse leakage current at 25 °C, per Table on page 2 of Vishay Document #88365. This ultra-low leakage preserves efficiency in always-on circuits and avoids false triggering in high-impedance sensor bias networks, especially critical in battery-powered industrial nodes.
Can P4KE160CHE3/73 be used in bidirectional configurations?
No, P4KE160CHE3/73 is a unidirectional TVS diode - its cathode marking and specified VBR/VWM values apply only in reverse-bias mode. For bidirectional protection, Vishay specifies CA-suffix variants (e.g., P4KE160CA). Using P4KE160CHE3/73 in bidirectional circuits risks forward conduction failure during negative transients and violates the device's intended operating quadrant.
