Product details
Overview
P6KE160-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR) at 1 mA, 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive body control modules to safeguard microcontrollers against load-dump transients.
For engineers reviewing the P6KE160-E3/73 datasheet, P6KE160-E3/73 pinout, P6KE160-E3/73 application, or P6KE160-E3/73 equivalent, this device is evaluated for robustness in 12 V/24 V vehicle electrical systems, ESD immunity per ISO 10605, and compliance with AEC-Q101 stress testing - critical when selecting TVS components for under-hood electronics with extended temperature operation up to +175 °C.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VWM = 136 V, then avalanches sharply at VBR = 152–168 V to divert surge energy away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM).
Thermal performance is defined by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), enabling reliable operation at TJ = –55 to +175 °C. The DO-204AC (DO-15) package supports manual or wave soldering per JESD 22-B106 (275 °C, 10 s max).

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 VC (219 V), but SMC package (DO-214AB); 600 W rating, lower RθJA = 40 °C/W. | Better thermal performance in high-density PCB layouts; requires surface-mount reflow instead of through-hole assembly. | Select SMBJ160A when board space is constrained and thermal management prioritized over legacy assembly compatibility. |
| 1.5KE160A | Identical electrical specs (VWM, VBR, VC, PPPM), same DO-204AC package, but commercial-grade only (not AEC-Q101 qualified). | Lacks automotive qualification; suitable for industrial or consumer applications where AEC-Q101 is not mandated. | Choose 1.5KE160A for cost-sensitive non-automotive designs where AEC-Q101 is unnecessary and DO-15 footprint must be retained. |
Compared with SMBJ160A and 1.5KE160A, P6KE160-E3/73 uniquely combines AEC-Q101 qualification, DO-204AC through-hole compatibility, and verified 175 °C operation - making it the preferred choice for automotive body electronics requiring long-term reliability and legacy manufacturing support.

FAQ
What is the maximum clamping voltage of the P6KE160-E3/73 under a 10/1000 µs surge?
The P6KE160-E3/73 exhibits a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 2.7 A using the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88369 and defines the upper voltage limit imposed on protected circuitry during transient events - a critical parameter for ensuring downstream ICs remain within absolute maximum ratings.
Is the P6KE160-E3/73 qualified for automotive applications?
Yes, the P6KE160-E3/73 is AEC-Q101 qualified, as confirmed by Vishay's documentation (note "(1) AEC-Q101 qualified" on page 3). This qualification covers stress tests including high-temperature operating life, temperature cycling, and humidity bias HTRB - validating its suitability for under-hood and cabin electronics such as body control modules and lighting controllers where reliability at 175 °C junction temperature is mandatory.
What does the 'E3/73' suffix indicate in P6KE160-E3/73?
The 'E3' suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while '/73' specifies packaging in 73 mm tape-and-reel format (4000 pcs/reel). This differs from '/54' (13" reel) and confirms the part meets environmental compliance standards without lead-free exemptions, supporting automated SMT placement in high-volume manufacturing.
How does the P6KE160-E3/73 compare to bi-directional TVS diodes like P6KE160CA?
The P6KE160-E3/73 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6KE160CA is bi-directional with no polarity marking and symmetric clamping in both directions. The P6KE160-E3/73 offers lower leakage (<1 µA at 136 V) and is optimized for DC rail protection, while P6KE160CA suits AC-coupled or floating signal lines - selection depends strictly on circuit topology and grounding scheme.
Can the P6KE160-E3/73 be used in parallel for higher surge current handling?
No - the P6KE160-E3/73 is not recommended for parallel operation due to inherent VBR mismatch (152–168 V range) causing current imbalance and potential thermal runaway. For higher surge capacity, Vishay recommends selecting a single higher-rated device (e.g., P6KE200A) or verifying matched-bin parts with <5 % VBR spread under controlled conditions - standard P6KE160-E3/73 units lack factory-matching for paralleling.
