Product details
Overview
P6KE30CA-E3/54 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 30 V breakdown voltage (VBR min/max = 28.5–31.5 V at 1.0 mA), 41.4 V maximum clamping voltage (VC) at 14.5 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE30CA-E3/54 datasheet, P6KE30CA-E3/54 pinout, P6KE30CA-E3/54 application, or P6KE30CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compliance with UL 497B for telecom and industrial surge protection standards.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
The device is rated for -55 °C to +175 °C operating junction temperature, supports 100 A non-repetitive forward surge current (IFSM), and exhibits 0.097 %/°C temperature coefficient of VBR, ensuring predictable voltage threshold drift across thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V at 1.0 mA - defines reliable conduction onset threshold for transient suppression |
| VWM | 25.6 V - maximum continuous working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 41.4 V at 14.5 A - clamped voltage during worst-case 600 W surge, limiting downstream stress |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform, critical for lightning/ESD immunity |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance, determines derating above 25 °C ambient |
| TJ max | +175 °C - maximum junction temperature, enabling operation in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33CA | DO-214AA package, 33 V VBR, same 600 W PPPM, lower RθJA (50 °C/W) | Surface-mount layout; higher power density but requires reflow-compatible PCB design | Select for space-constrained SMT designs needing identical clamping performance with improved thermal performance |
| 1.5KE33CA | DO-201AD package, 33 V VBR, 1500 W PPPM | Higher surge capacity; larger footprint and higher VC (53.3 V) | Choose when legacy through-hole compatibility is required and 1500 W surge margin justifies larger size and higher clamping voltage |
Compared with P6KE30CA-E3/54, SMBJ33CA offers superior thermal performance in SMT form factor but lacks AEC-Q101 qualification, while 1.5KE33CA delivers higher surge robustness in legacy DO-201AD packaging but increases board area and clamping voltage - making P6KE30CA-E3/54 optimal for cost-sensitive, AEC-Q101-compliant DO-15 designs.

FAQ
What is the breakdown voltage range for P6KE30CA-E3/54?
The P6KE30CA-E3/54 has a specified breakdown voltage (VBR) range of 28.5 V to 31.5 V at 1.0 mA test current, measured in both directions due to its bidirectional construction. This range ensures consistent clamping onset across polarity reversals and supports reliable operation in AC-coupled or floating circuits where transient polarity is unpredictable. The value is confirmed in Vishay's official datasheet revision 27-Sep-2021, Document Number 88369.
Is P6KE30CA-E3/54 qualified for automotive applications?
Yes, P6KE30CA-E3/54 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet under "Notes" and "Ratings and Characteristics Curves" sections. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and accelerated life testing - validating its suitability for under-hood and chassis-mounted automotive electronics. The HE3 suffix denotes AEC-Q101 grade, but P6KE30CA-E3/54 itself carries E3 (commercial) with AEC-Q101 qualification noted in documentation.
What is the maximum clamping voltage of P6KE30CA-E3/54 at rated peak pulse current?
The maximum clamping voltage (VC) of P6KE30CA-E3/54 is 41.4 V at 14.5 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case surge events and is critical for ensuring downstream ICs remain within their absolute maximum voltage ratings. It is measured per ANSI/IEEE C62.35 and documented in Table "ELECTRICAL CHARACTERISTICS" of the Vishay datasheet.
Does P6KE30CA-E3/54 have polarity markings on its package?
No, P6KE30CA-E3/54 does not have polarity markings because it is a bidirectional TVS diode. Unlike unidirectional types (which use a cathode band), the CA-suffixed variants are symmetrical and function identically regardless of lead orientation. This simplifies PCB layout and eliminates risk of incorrect installation - a key advantage in differential signal protection and AC line applications where polarity reversal is inherent.
What is the thermal resistance of P6KE30CA-E3/54 from junction to ambient?
The typical junction-to-ambient thermal resistance (RθJA) of P6KE30CA-E3/54 is 75 °C/W, as specified in the "THERMAL CHARACTERISTICS" section of the Vishay datasheet. This value assumes standard JEDEC test conditions (single device on FR-4 board with 1 in² copper pad). For higher-power or elevated-temperature applications, thermal derating must be applied per Figure 5 (Power Derating Curve), especially above 25 °C ambient.
