Product details
Overview
P6KE30-E3/54 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 30 V breakdown voltage (VBR = 28.5–31.5 V), 41.4 V maximum clamping voltage at 14.5 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and DO-204AC (DO-15) package. It protects MOSFETs, ICs, and sensor interfaces against inductive switching transients in automotive and industrial control modules.
For engineers reviewing the P6KE30-E3/54 datasheet, P6KE30-E3/54 pinout, P6KE30-E3/54 application, or P6KE30-E3/54 equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, standoff voltage compatibility with nominal rail voltage (e.g., 24 V systems), thermal resistance (RθJL = 20 °C/W), and AEC-Q101 qualification status for automotive use cases.
Technical Context
The P6KE30-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to ESD and surge events. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked - such as 24 V supply inputs feeding microcontrollers or CAN transceivers.
Clamping performance is defined at IPPM = 14.5 A (10/1000 µs waveform), yielding VC ≤ 41.4 V, while maintaining low incremental surge resistance and stable temperature coefficient of 0.097 %/°C. It sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and exhibits 1.0 µA max reverse leakage at 25.6 V standoff voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V - Ensures reliable avalanche initiation above 24 V nominal rail without premature conduction |
| VWM | 25.6 V - Standoff voltage compatible with 24 V ±5% industrial power buses |
| VC @ IPPM | ≤41.4 V - Clamps transient energy to safe level below 45 V absolute max rating of common 3.3 V/5 V logic ICs |
| IPPM | 14.5 A - Peak surge current handling per 10/1000 µs standard lightning/surge test waveform |
| PPPM | 600 W - Sustains high-energy transients typical of relay coil flyback or motor driver switching |
| RθJL | 20 °C/W - Enables effective heat dissipation through PCB copper pour or lead frame without heatsink |
| TJ max | +175 °C - Supports operation in under-hood automotive environments and sealed industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Same VBR range (28.5–31.5 V), but SMC (DO-214AB) surface-mount package; 600 W rating; RθJA = 40 °C/W vs. 75 °C/W for P6KE30-E3/54 | Designed for automated SMT assembly; less suitable for through-hole prototyping or high-vibration mechanical mounting | Select SMBJ30A for space-constrained PCBs requiring reflow compatibility and lower profile; retain P6KE30-E3/54 for manual assembly, repairability, or lead-frame thermal relief. |
| 1.5KE30A | Same DO-204AC package and VBR, but 1500 W peak power (10/1000 µs); larger die size; higher IPPM = 32.7 A; VF = 3.5 V at 50 A | Better suited for high-energy industrial surge environments (IEC 61000-4-5 Level 4), but over-spec'd for basic ESD/inductive clamp needs | Choose 1.5KE30A only when validated surge threat exceeds 600 W; otherwise P6KE30-E3/54 offers optimal cost, size, and thermal balance for commercial-grade protection. |
Compared with SMBJ30A and 1.5KE30A, P6KE30-E3/54 delivers the best trade-off of proven reliability in axial-leaded form, AEC-Q101 qualification, and precise 600 W surge capacity - making it ideal for cost-sensitive, thermally constrained, and automotive-qualified designs where SMT is not mandatory.

FAQ
What is the breakdown voltage tolerance for P6KE30-E3/54?
The P6KE30-E3/54 has a specified breakdown voltage range of 28.5 V to 31.5 V at 1.0 mA test current (VBR min/max). This ±5% tolerance ensures consistent avalanche initiation across production lots while allowing design margin for 24 V system variations. The value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 18-Sep-12, Document Number 88369.
Is P6KE30-E3/54 suitable for automotive applications?
Yes - the P6KE30-E3/54 carries the E3 suffix, indicating RoHS compliance and AEC-Q101 qualification per Vishay's documentation. It meets stress testing requirements for temperature cycling, humidity, mechanical shock, and surge endurance relevant to automotive ECUs and body control modules. Its 175 °C max junction temperature and stable clamping behavior support under-hood deployment.
How does the clamping voltage of P6KE30-E3/54 compare to its standoff voltage?
The P6KE30-E3/54 has a standoff voltage (VWM) of 25.6 V and a maximum clamping voltage (VC) of 41.4 V at 14.5 A. This 15.8 V differential provides 15.8 V of headroom above the operating rail - sufficient to protect 36 V-rated components while avoiding false triggering during normal 24 V operation with ripple. The clamping ratio (VC/VBR) is ~1.38, reflecting efficient avalanche conduction.
What is the thermal resistance from junction to lead for P6KE30-E3/54?
The P6KE30-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling effective heat transfer from the silicon die to the PCB copper or chassis via its axial leads. This value supports continuous power dissipation up to 5.0 W at TL = 75 °C and allows designers to estimate temperature rise under surge conditions using ΔT = Psurge × RθJL.
Can P6KE30-E3/54 be used in bidirectional configurations?
No - P6KE30-E3/54 is a unidirectional TVS diode, identified by the "A" suffix (not "CA"). It conducts only in reverse bias above VBR and blocks forward current beyond ~3.5 V. For bidirectional protection (e.g., AC lines or data buses), Vishay specifies variants like P6KE30CA. Using P6KE30-E3/54 in AC applications risks forward conduction and failure.
