Product details
Overview
P6KE6.8CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 6.8 V nominal breakdown voltage (VBR), 10.5 V maximum clamping voltage (VC) at 57.1 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform), making it suitable for protecting automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching surges.
For engineers reviewing the P6KE6.8CAHE3/54 datasheet, P6KE6.8CAHE3/54 pinout, P6KE6.8CAHE3/54 application, or P6KE6.8CAHE3/54 equivalent, this device delivers AEC-Q101-qualified transient protection with verified bidirectional clamping behavior, low leakage (<1000 μA at 5.8 V), and thermal robustness up to 175 °C junction temperature - critical for under-hood automotive and high-reliability industrial designs.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5% min/max), fast response time (<1 ns), and low incremental surge resistance - key for limiting voltage overshoot during sub-microsecond transients.
The device complies with AEC-Q101 stress testing for automotive use and supports soldering per J-STD-002/JESD 22-B102. With RθJL = 20 °C/W and RθJA = 75 °C/W, thermal performance is optimized for lead-mounted PCB layouts without heatsinking, while the DO-15 package maintains UL 94 V-0 flammability compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA test current - defines precise clamping onset threshold for bidirectional overvoltage events |

| VC @ IPPM | 10.5 V at 57.1 A (10/1000 μs) - actual worst-case clamped voltage seen by protected circuit during surge |
| PPPM | 600 W - peak transient energy absorption capability without failure, validated per repetitive 0.01% duty cycle |
| TJ max. | +175 °C - enables operation in under-hood automotive environments and high-ambient industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8CA | Same VBR (6.45–7.14 V) and VC (10.5 V), but SMC package (higher IPPM = 64.5 A, lower RθJA = 40 °C/W) | Better suited for higher-power industrial surge events; requires surface-mount layout vs. through-hole DO-15 | Select SMBJ6.8CA when board space allows SMD placement and thermal management demands higher surge margin. |
| 1.5KE6.8CA | Same VBR/VC, but 1500 W PPPM rating and larger DO-201AD package; higher IPPM = 143 A | Targeted at high-energy utility-grade or telecom infrastructure protection where single-event energy exceeds 600 W | Choose 1.5KE6.8CA only when system-level surge testing requires >600 W headroom and mechanical constraints allow larger axial package. |
Compared with SMBJ6.8CA and 1.5KE6.8CA, P6KE6.8CAHE3/54 offers optimal balance of AEC-Q101 qualification, DO-15 through-hole compatibility, and cost-effective 600 W surge handling - making it the preferred choice for volume automotive and industrial control applications where qualification and manufacturability are prioritized over extreme power rating.

FAQ
What is the breakdown voltage tolerance for P6KE6.8CAHE3/54?
The P6KE6.8CAHE3/54 has a specified breakdown voltage (VBR) range of 6.45 V to 7.14 V at 10 mA test current, representing a ±5% tolerance around the nominal 6.8 V value. This tight tolerance ensures consistent clamping behavior across production lots and supports predictable circuit protection design. The P6KE6.8CAHE3/54 maintains this specification under standard test conditions (TA = 25 °C) and is validated per Vishay's production screening protocols.
Is P6KE6.8CAHE3/54 suitable for automotive applications?
Yes, P6KE6.8CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments with operating junction temperatures up to +175 °C. Its DO-15 package, glass-passivated junction, and bidirectional clamping make it appropriate for protecting engine control units, body control modules, and ADAS sensor interfaces. The P6KE6.8CAHE3/54 HE3 suffix confirms full AEC-Q101 compliance per Vishay's documentation.
What is the maximum clamping voltage of P6KE6.8CAHE3/54 during a surge event?
The P6KE6.8CAHE3/54 exhibits a maximum clamping voltage (VC) of 10.5 V when subjected to its rated peak pulse current of 57.1 A using the standard 10/1000 μs waveform. This value represents the worst-case voltage imposed on the protected circuit during surge conduction and is measured at TA = 25 °C. The P6KE6.8CAHE3/54 maintains this clamping performance across its qualified temperature range.
Does P6KE6.8CAHE3/54 have polarity markings on the package?
No, P6KE6.8CAHE3/54 does not feature polarity markings because it is a bidirectional TVS diode - both terminals are functionally identical and interchangeable. Unlike unidirectional types (which use a cathode band), the P6KE6.8CAHE3/54 relies on symmetrical internal structure to provide equal clamping in either direction. This eliminates orientation concerns during manual or automated assembly of the P6KE6.8CAHE3/54.
What is the lead finish and solderability specification for P6KE6.8CAHE3/54?
P6KE6.8CAHE3/54 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 for solderability, supporting wave and reflow processes. The HE3 suffix indicates JESD 201 Class 2 whisker resistance, and the device withstands solder dip at 275 °C for up to 10 seconds. These specifications ensure robust interconnect reliability in high-volume manufacturing of the P6KE6.8CAHE3/54.
