Product details
Overview
P6KE180A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 154 V standoff voltage (VWM), 171–189 V breakdown voltage (VBR) at 1 mA, 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P6KE180A-E3/73 datasheet, P6KE180A-E3/73 pinout, P6KE180A-E3/73 application, or P6KE180A-E3/73 equivalent, key selection criteria include clamping performance under 2.4 A surge, thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and compatibility with 175 °C max junction temperature designs in automotive and industrial power rails.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VWM = 154 V, then avalanches sharply at VBR = 171–189 V to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for single-pulse and low-duty-cycle (<0.01 %) repetitive transients, the device delivers 246 V clamping at IPPM = 2.4 A (10/1000 μs), with thermal derating per Fig. 2 above TA = 25 °C and maximum TJ = 175 °C. Lead temperature limits (TL = 75 °C) define its 5.0 W steady-state power dissipation capability on infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 154 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC working margin. |
| VBR (min/max) | 171 V / 189 V at 1 mA - Tight breakdown window ensures predictable turn-on timing across production lots. |
| VC @ IPPM | 246 V at 2.4 A - Clamping voltage during 10/1000 μs surge; determines maximum stress imposed on protected IC/MOSFET. |
| PPPM | 600 W - Peak pulse power handling capacity; validates robustness against IEC 61000-4-5 Level 4 surges. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; enables accurate transient thermal modeling for PCB copper pour design. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial motor drive environments. |
| ID @ VWM | 1.0 μA - Reverse leakage at standoff voltage; negligible loading on high-impedance sensor bias networks. |

Use Value: Withstands 100 A non-repetitive forward surge (IFSM), surviving repeated motor stall-induced back-EMF spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Same VWM (154 V) and VC (246 V), but SMC package (higher IPPM = 2.6 A); RθJA = 40 °C/W vs. 75 °C/W for DO-15. | Better thermal performance in high-density layouts; requires surface-mount footprint instead of through-hole. | Select SMBJ180A when board space allows SMD placement and higher surge margin is needed. |
| 1.5KE180A | Identical electrical specs (VWM, VBR, VC, PPPM), same DO-15 package, but rated for 1.5 kW peak pulse power (10/1000 μs). | Higher surge endurance for infrequent but extreme transients (e.g., utility grid coupling); no AEC-Q101 qualification. | Choose 1.5KE180A for non-automotive industrial systems where 1.5 kW surge headroom justifies cost premium. |
Compared with SMBJ180A and 1.5KE180A, P6KE180A-E3/73 offers AEC-Q101 qualification in a cost-optimized DO-15 through-hole package, making it ideal for automotive body control modules and industrial controllers where qualification and legacy assembly compatibility are prioritized over maximum surge rating or SMD density.

FAQ
What is the maximum clamping voltage of P6KE180A-E3/73 under standard test conditions?
The maximum clamping voltage (VC) of P6KE180A-E3/73 is 246 V when subjected to a 10/1000 μs waveform peak pulse current (IPPM) of 2.4 A. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events. The P6KE180A-E3/73 maintains this clamping performance consistently across its qualified operating temperature range.
Is P6KE180A-E3/73 qualified for automotive applications?
Yes, P6KE180A-E3/73 carries the E3 suffix, indicating RoHS compliance and AEC-Q101 qualification per Vishay's documentation. This certification confirms its suitability for automotive electronic control units, including body electronics and power distribution modules, where reliability under thermal cycling, vibration, and surge stress is mandatory. The P6KE180A-E3/73 meets all stress test requirements defined in AEC-Q101 Rev D.
What is the standoff voltage rating of P6KE180A-E3/73, and how does it relate to system design?
The standoff voltage (VWM) of P6KE180A-E3/73 is 154 V, representing the maximum continuous reverse voltage the device can withstand without exceeding 1.0 μA leakage current. In system design, this value must exceed the peak normal operating voltage - for example, ≥154 V is required for 120 VAC-derived DC rails or 24 V automotive systems with load dump margins. Exceeding VWM risks premature conduction and power loss in the P6KE180A-E3/73.
Does P6KE180A-E3/73 have bidirectional capability?
No, P6KE180A-E3/73 is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). It conducts only in reverse-bias avalanche mode, with cathode marked by a color band. For bidirectional protection (e.g., AC line or differential data lines), the P6KE180CA variant would be required. Using P6KE180A-E3/73 in bidirectional configurations may result in forward conduction damage during negative transients.
What is the thermal resistance specification for P6KE180A-E3/73, and why does it matter?
P6KE180A-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. RθJL is critical for estimating temperature rise during short-duration surges, directly impacting VC stability and reliability. Designers use this value to size copper land patterns and ensure peak junction temperature stays below 175 °C during worst-case transient events. The P6KE180A-E3/73 thermal model supports accurate SPICE-based transient thermal simulation.
