Product details
Overview
P6KE120A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 114 V minimum breakdown voltage (VBR), 102 V maximum standoff voltage (VWM), 165 V clamping voltage (VC) at 3.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive engine control units, industrial PLC I/O modules, and telecom power supply inputs.
For engineers reviewing the P6KE120A-E3/54 datasheet, P6KE120A-E3/54 pinout, P6KE120A-E3/54 application, or P6KE120A-E3/54 equivalent, this device delivers verified AEC-Q101 qualification, DO-15 package compatibility, low thermal resistance (20 °C/W junction-to-lead), and precise clamping performance critical for protecting MOSFET gates, microcontroller reset lines, and CAN transceiver power domains against lightning-induced surges and inductive switching transients.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal conditions it presents <1 µA leakage at 102 V, then rapidly avalanches when transient voltage exceeds 114 V to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and repeatable clamping behavior across temperature (-55 °C to +175 °C).
The device sustains 100 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 0.107 %/°C VBR temperature coefficient, and maintains 3.5 V max forward voltage at 50 A - enabling robust protection of 12 V–48 V systems without compromising upstream fuse coordination or crowbar response timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 102 V maximum - defines highest continuous DC operating voltage before leakage exceeds 1 µA; sets system rail margin for 120 V nominal applications. |
| VBR (min/max) | 114 V / 126 V at 1 mA - specifies guaranteed avalanche onset range; ensures reliable triggering above worst-case system overvoltage thresholds. |
| VC @ IPPM | 165 V at 3.6 A (10/1000 µs) - maximum clamped voltage seen by protected IC during surge; determines minimum safe voltage headroom for downstream components. |
| PPPM | 600 W - peak transient power handling capability; supports EN 61000-4-5 Level 4 (4 kV line-to-line) surge immunity in properly designed layouts. |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables direct solder-mount thermal path to PCB copper pour for sustained 5 W dissipation at TL = 75 °C. |
| TJ max | +175 °C - maximum junction temperature; allows operation in under-hood automotive environments and sealed industrial enclosures without derating. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TCT, and ESD testing; approved for use in engine management, body control, and ADAS power domains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ120A | Same VWM/VBR/VC specs but SMC (DO-214AB) package; 100 W lower PPPM (500 W vs. 600 W); 30 % smaller footprint. | Better suited for space-constrained PCBs where 100 W margin reduction is acceptable; requires revalidation of thermal layout due to higher RθJA. | Select SMBJ120A when board area is critical and surge test level is ≤Level 3 (2 kV); retain P6KE120A-E3/54 for full Level 4 compliance or high-temperature ambient operation. |
| 1.5KE120A | Same DO-15 package and electrical specs but commercial-grade only; not AEC-Q101 qualified; 10 % wider VBR tolerance (±10 % vs. ±5 %). | Limited to non-automotive industrial or consumer applications where qualification and tighter parametric control are not required. | Choose 1.5KE120A for cost-sensitive non-automotive designs; use P6KE120A-E3/54 where automotive qualification, tighter VBR control, or extended temperature validation is mandatory. |
Compared with SMBJ120A and 1.5KE120A, P6KE120A-E3/54 provides the highest surge power margin (600 W), tightest VBR tolerance (±5 %), and automotive qualification - making it the preferred choice for mission-critical 120 V rail protection where thermal robustness and reliability certification are non-negotiable.

FAQ
What is the maximum clamping voltage of P6KE120A-E3/54 under standard surge conditions?
The P6KE120A-E3/54 has a maximum clamping voltage (VC) of 165 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 3.6 A. This value is measured per JEDEC standards and guarantees that protected circuitry will not experience voltages exceeding 165 V during standardized surge events - a key parameter for ensuring compatibility with 200 V-rated downstream capacitors and regulators in the P6KE120A-E3/54 application chain.
Is P6KE120A-E3/54 suitable for automotive applications?
Yes, P6KE120A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS power domains. Its -55 °C to +175 °C operating junction temperature range, glass-passivated junction, and validated HTOL/thermal cycling performance make it appropriate for under-hood and cabin-mounted systems - confirming P6KE120A-E3/54 meets stringent automotive reliability requirements beyond commercial-grade alternatives.
How does the DO-15 package of P6KE120A-E3/54 affect thermal performance?
The DO-15 (DO-204AC) package of P6KE120A-E3/54 delivers a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer to PCB copper pours or metal-core substrates. This allows the P6KE120A-E3/54 to sustain its 5.0 W steady-state power dissipation at 75 °C lead temperature without external heatsinking - a critical advantage over surface-mount equivalents in high-ambient-temperature environments where airflow is limited.
What is the reverse leakage current specification for P6KE120A-E3/54 at its maximum standoff voltage?
At its maximum standoff voltage (VWM) of 102 V and ambient temperature of 25 °C, the P6KE120A-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA. This ultra-low leakage ensures minimal standby power loss in battery-powered systems and prevents false triggering in high-impedance sensing circuits - a design-critical parameter confirmed in the Vishay P6KE120A-E3/54 datasheet Table 1.
Can P6KE120A-E3/54 be used in bidirectional protection configurations?
No, P6KE120A-E3/54 is a unidirectional TVS diode, identifiable by its cathode band marking and specified parameters (e.g., VF = 3.5 V at 50 A). For bidirectional protection, Vishay offers the P6KE120CA variant - which shares identical VWM, VBR, and VC ratings but operates symmetrically in both polarities. Using P6KE120A-E3/54 in AC or floating-rail applications would result in unintended forward conduction and failure.
