Product details
Overview
P6KE12C-E3/54 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection of sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 12 V breakdown voltage (VBR min/max = 11.4 V / 12.6 V), 16.7 V maximum clamping voltage at 35.9 A peak pulse current, 600 W peak pulse power rating (10/1000 µs waveform), and DO-204AC (DO-15) package. It is used in automotive sensor signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the P6KE12C-E3/54 datasheet, P6KE12C-E3/54 pinout, P6KE12C-E3/54 application, or P6KE12C-E3/54 equivalent, key selection criteria include clamping voltage vs. surge current, unidirectional/bi-directional polarity requirement, thermal resistance (RθJL = 20 °C/W), RoHS compliance (E3 suffix), and AEC-Q101 qualification status - critical for automotive-grade transient suppression.
Technical Context
This bi-directional TVS operates symmetrically in both polarities with no cathode marking, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction delivers fast response time (<1 ns), low incremental surge resistance, and stable clamping performance under repetitive 10/1000 µs transients at 0.01% duty cycle.
The device is rated for 175 °C maximum junction temperature and exhibits a temperature coefficient of 0.078 %/°C on VBR. Its 5.0 W steady-state power dissipation (at TL = 75 °C) and 20 °C/W junction-to-lead thermal resistance support reliable operation in thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.4 V / 12.6 V at IT = 1.0 mA - defines precise voltage threshold where avalanche conduction begins in either direction |
| VWM | 10.2 V - maximum continuous reverse working voltage before leakage exceeds 5.0 µA; sets safe operating margin below clamping |
| VC @ IPPM | 16.7 V at 35.9 A (10/1000 µs) - maximum clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient power handling capability; determines survivability against standardized lightning/surge waveforms |
| IPPM | 35.9 A - peak pulse current corresponding to VC; used to size series impedance and verify system-level surge margin |

FAQ
What does the "C" suffix in P6KE12C-E3/54 indicate?
The "C" suffix denotes that the P6KE12C-E3/54 is a bi-directional Transient Voltage Suppressor. Unlike uni-directional variants (e.g., P6KE12A), it provides symmetrical clamping in both polarities with no cathode marking - ideal for AC signal lines, differential buses, or floating grounds where polarity cannot be guaranteed. This is explicitly defined in the Vishay datasheet section "Devices for Bi-Direction Applications".
Is P6KE12C-E3/54 AEC-Q101 qualified?
No - the P6KE12C-E3/54 uses the E3 suffix, indicating RoHS compliance and JESD 201 Class 1A whisker resistance, but not AEC-Q101 qualification. For AEC-Q101 compliance, the correct variant is P6KE12CHE3/54 (HE3 suffix). The datasheet confirms AEC-Q101 qualification applies only to HE3-suffixed parts, not E3-suffixed ones like P6KE12C-E3/54.
What is the maximum clamping voltage of P6KE12C-E3/54 and at what current is it specified?
The maximum clamping voltage (VC) of P6KE12C-E3/54 is 16.7 V, measured at a peak pulse current (IPPM) of 35.9 A using the standardized 10/1000 µs double-exponential waveform. This value is listed in the Electrical Characteristics table on page 2 of the Vishay datasheet (Document Number: 88369) under the row for P6KE12A - applicable to P6KE12C due to identical VBR range and bi-directional symmetry.
Can P6KE12C-E3/54 replace P6KE12A in a design?
No - P6KE12C-E3/54 and P6KE12A are functionally distinct: P6KE12A is uni-directional (cathode-banded), while P6KE12C-E3/54 is bi-directional (no band). Substituting one for the other risks incorrect clamping behavior in DC-biased circuits. The datasheet explicitly states polarity must match application requirements, and bi-directional types are not drop-in replacements for uni-directional ones without circuit review.
What is the thermal resistance and how does it affect PCB layout for P6KE12C-E3/54?
The P6KE12C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning each watt of sustained power raises the junction temperature 20 °C above lead temperature. For reliable operation, leads must be soldered to adequate copper area (≥1 cm² per lead recommended) to maintain TL ≤ 75 °C - otherwise, derating of the 5.0 W steady-state power dissipation is required per Figure 5 in the datasheet.
