Product details
Overview
P6KE160CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 160 V breakdown voltage (VBR min = 152 V, max = 168 V), 136 V stand-off voltage (VWM), 219 V clamping voltage at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P6KE160CHE3/73 datasheet, P6KE160CHE3/73 pinout, P6KE160CHE3/73 application, or P6KE160CHE3/73 equivalent, key selection criteria include verified clamping performance under 2.7 A surge, AEC-Q101 qualification for automotive use, thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM = 136 V, it avalanches into low-impedance conduction to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
Rated for repetitive 0.01 % duty cycle surges, the device sustains 600 W peak pulse power with derating above TA = 25 °C (per Fig. 2), and handles 100 A non-repetitive forward surge (IFSM) per 8.3 ms half-sine wave. Junction temperature range spans –55 °C to +175 °C, supporting under-hood automotive deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 152 V / 168 V - defines reliable avalanche initiation window; ensures consistent clamping onset across production lot and temperature |
| VWM | 136 V - maximum continuous reverse operating voltage; sets safe DC rail margin before conduction begins |
| VC @ IPPM | 219 V @ 2.7 A - clamping voltage during 10/1000 µs surge; determines maximum stress imposed on protected circuit |
| PPPM | 600 W - peak pulse power handling; enables robust protection against lightning-induced transients and load dump events |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; supports high-power dissipation without external heatsink in leaded PCB layouts |
| TJ max | +175 °C - maximum junction temperature; qualifies for under-hood automotive environments and high-ambient industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, temperature cycling, and ESD testing per AEC standard |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads comply with J-STD-002 solderability and JESD 201 class 2 whisker resistance (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/52 (Vishay) | Same VBR range (152–168 V) but SMC package (DO-214AB); 600 W rating; lower RθJA (50 °C/W vs. 75 °C/W) | Better thermal performance in high-density layouts; requires surface-mount assembly instead of through-hole | Select when board space is constrained and reflow capability exists; not drop-in compatible due to footprint change |
| 1.5KE160A (ON Semiconductor) | Identical DO-204AC package and electrical specs (VBR, VC, PPPM); lacks AEC-Q101 qualification; commercial-grade only | Suitable for industrial/commercial systems without automotive qualification requirements | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with SMBJ160A-E3/52 and 1.5KE160A, P6KE160CHE3/73 uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and verified 20 °C/W junction-to-lead thermal resistance - making it optimal for legacy automotive harness interfaces and service-replaceable modules requiring mechanical robustness.

FAQ
What is the clamping voltage of P6KE160CHE3/73 and how is it measured?
The clamping voltage (VC) of P6KE160CHE3/73 is 219 V, measured at 2.7 A peak pulse current using a 10/1000 µs waveform per IEC 61000-4-5. This value represents the maximum voltage seen across the device terminals during standardized surge testing and directly determines the upper voltage stress applied to protected components. The P6KE160CHE3/73 achieves this clamping performance while maintaining 136 V stand-off voltage, providing a 83 V overvoltage margin before conduction begins.
Is P6KE160CHE3/73 qualified for automotive applications?
Yes, P6KE160CHE3/73 is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's datasheet (Document Number 88369, Revision 18-Sep-12). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD robustness - validating its use in engine control units, body electronics, and other automotive subsystems where reliability under harsh conditions is mandatory. The P6KE160CHE3/73 meets these requirements in its DO-204AC package with matte tin-plated leads.
What is the difference between P6KE160CHE3/73 and P6KE160A-E3/73?
P6KE160CHE3/73 is AEC-Q101 qualified (HE3 suffix), while P6KE160A-E3/73 is commercial-grade only (E3 suffix). Both share identical electrical parameters (VBR, VC, PPPM) and DO-204AC packaging, but the HE3 variant undergoes additional automotive-specific reliability testing including extended temperature cycling and accelerated life testing. The P6KE160CHE3/73 also meets JESD 201 class 2 whisker resistance, whereas the E3 version meets class 1A - making P6KE160CHE3/73 the required choice for automotive production programs.
Can P6KE160CHE3/73 be used for bi-directional transient suppression?
No, P6KE160CHE3/73 is a uni-directional TVS diode, indicated by the "A" suffix and presence of a cathode band. Bi-directional variants use the "CA" suffix (e.g., P6KE160CA). Uni-directional devices like P6KE160CHE3/73 conduct only in reverse bias above VWM; they must be oriented with cathode toward the protected line and anode to reference ground. Using P6KE160CHE3/73 in AC or floating applications would require two devices in series opposition - not recommended when a single P6KE160CA provides symmetric clamping.
What is the thermal resistance and maximum junction temperature of P6KE160CHE3/73?
P6KE160CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and a maximum junction temperature (TJ) of +175 °C. This allows the device to dissipate surge energy efficiently through its leads into the PCB copper, supporting operation in high-ambient environments such as automotive under-hood locations. The +175 °C rating enables sustained functionality even during prolonged thermal stress, and the 20 °C/W RθJL confirms effective heat transfer without requiring external heatsinking in standard through-hole mounting configurations.
