Product details
Overview
P6KE160CAHE3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on power and signal lines. It features a 136 V standoff voltage (VWM), 152–168 V breakdown voltage (VBR) at 1 mA, 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the P6KE160CAHE3/73 datasheet, P6KE160CAHE3/73 pinout, P6KE160CAHE3/73 application, or P6KE160CAHE3/73 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal derating behavior, clamping performance under surge, and direct alternatives for ESD/surge protection design-in.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with no polarity marking on the DO-15 body. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing lightning-induced surges and inductive switching spikes.
Rated for -55 °C to +175 °C junction temperature, it supports high-reliability automotive use via AEC-Q101 qualification (HE3 suffix), and exhibits 0.108 %/°C temperature coefficient of VBR - ensuring stable clamping across thermal operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed minimum/maximum breakdown range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by protected circuit during 10/1000 μs surge; directly limits stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability per transient event; validates suitability for IEC 61000-4-5 Level 4 compliance designs. |
| IR (Reverse Leakage) | 1.0 μA max at VWM - Negligible standby current; avoids loading sensitive reference or bias networks. |
| TJ max | +175 °C - Enables placement near hot components (e.g., power MOSFETs, motor drivers) without thermal derating penalties. |
| AEC-Q101 Qualified | Yes (HE3 suffix) - Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | DO-214AA package, 150 V VWM, 243 V VC at 2.5 A - lower clamping but smaller footprint and higher thermal resistance (RθJA = 110 °C/W). | Better suited for space-constrained PCBs; less effective in high-ambient-temperature industrial enclosures due to thermal limitations. | Select SMBJ150CA when board area is constrained and peak ambient temperature stays below 70 °C. |
| 1.5KE150CA | DO-201AD package, same 150 V VWM, 243 V VC at 2.5 A, but rated for 1500 W PPPM - larger size, higher surge margin, and higher IFSM (200 A). | Preferred for high-energy surge zones (e.g., AC mains input, outdoor telecom cabinets) where single-event energy exceeds 600 W capability. | Choose 1.5KE150CA when protecting against multi-kV lightning surges or long-line inductive transients requiring >1000 W headroom. |
Compared with P6KE160CAHE3/73, SMBJ150CA trades thermal robustness for compactness, while 1.5KE150CA offers higher surge capacity at the cost of DO-15 compatibility and board space - making P6KE160CAHE3/73 optimal for AEC-Q101-compliant, mid-energy automotive and industrial I/O protection.

FAQ
What does the 'CA' suffix indicate in P6KE160CAHE3/73?
The 'CA' suffix in P6KE160CAHE3/73 denotes a bidirectional configuration - meaning the device clamps voltage transients equally in both polarities, with no cathode marking on the DO-15 body. This is confirmed in Vishay's datasheet Document Number 88369, which specifies that CA-suffix variants are intended for AC-coupled or differential signal line protection where polarity reversal may occur. The P6KE160CAHE3/73 therefore functions identically whether installed in forward or reverse orientation.
Is P6KE160CAHE3/73 suitable for automotive applications?
Yes, P6KE160CAHE3/73 is explicitly AEC-Q101 qualified (denoted by the 'HE3' suffix), having passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. Its -55 °C to +175 °C operating range, 136 V standoff voltage, and 219 V clamping performance make it appropriate for engine bay sensors, body control modules, and infotainment power rail protection - all validated per Vishay's qualification report referenced in Document 88369.
How does the clamping voltage of P6KE160CAHE3/73 compare to its breakdown voltage?
The P6KE160CAHE3/73 has a breakdown voltage (VBR) range of 152–168 V at 1 mA and a maximum clamping voltage (VC) of 219 V at 2.7 A IPPM - yielding a clamping ratio (VC/VBR) of approximately 1.37. This ratio reflects low dynamic impedance during surge conduction and is consistent with Vishay's published data for the P6KE family. That ratio ensures protected circuits experience minimal overvoltage beyond the specified VBR window during real-world transients.
What is the thermal resistance of P6KE160CAHE3/73, and how does it affect PCB layout?
P6KE160CAHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W under standard conditions. Because it uses a DO-15 package with axial leads, effective heat dissipation relies on adequate copper pour connected to both leads and sufficient lead length (≥9.5 mm recommended). Layouts should avoid narrow traces and ensure ≥250 mils of copper per lead to maintain thermal performance - especially critical in high-duty-cycle surge environments.
Can P6KE160CAHE3/73 replace unidirectional P6KE160AHE3/73 in an existing design?
No - P6KE160CAHE3/73 is bidirectional and lacks polarity marking, whereas P6KE160AHE3/73 is unidirectional with a cathode band. Substituting them requires verifying circuit topology: bidirectional use is mandatory for AC signals or differential buses (e.g., RS-485), while unidirectional types are needed for DC power rails where reverse conduction must be blocked. The P6KE160CAHE3/73 will conduct in both directions above VBR, potentially disrupting DC bias if used incorrectly.
