Product details
Overview
P6KE110A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 110 V breakdown voltage (VBR min/max = 105–116 V), 94.0 V standoff voltage (VWM), 152 V clamping voltage (VC) at 3.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P6KE110A-E3/54 datasheet, P6KE110A-E3/54 pinout, P6KE110A-E3/54 application, or P6KE110A-E3/54 equivalent, key selection criteria include unidirectional polarity, glass-passivated junction, AEC-Q101 qualification (via HE3 variant), 175 °C max junction temperature, and compatibility with automated SMT placement via E3-compliant matte tin leads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (<1 μA leakage at 94.0 V), then rapidly avalanches below 152 V to divert transient energy away from downstream ICs. Its 20 °C/W junction-to-lead thermal resistance enables effective heat dissipation during repetitive surges.
The device uses a silicon planar junction structure with glass passivation for stable breakdown characteristics and low incremental surge resistance. It meets UL 497B recognition (QVGQ2) and complies with JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - ensures reliable conduction onset above 94.0 V operating rail while avoiding false triggering |
| VWM | 94.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 152 V @ 3.9 A - clamping voltage limits downstream component stress during 10/1000 μs transients |
| PPPM | 600 W - peak surge power handling capability per single 10/1000 μs pulse at 0.01% duty cycle |
| TJ max | +175 °C - enables operation in under-hood automotive and industrial environments without derating |
| RθJL | 20 °C/W - low thermal resistance allows efficient heat transfer to PCB copper or heatsinked leads |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 0.242–0.258 inch body length and 0.130–0.138 inch diameter |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated axial leads; cathode indicated by color band on one end. Leads are solderable per J-STD-002 and JESD 22-B102; compliant with UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Current entry point in forward bias; connected to protected circuit ground or low-side return | Enables unidirectional clamping: conducts only when cathode is >152 V above anode during transients |
| Cathode (color-banded end) | High-voltage terminal; connected to line being protected (e.g., +12 V rail, sensor input) | Provides low-impedance path to ground during overvoltage events; marking ensures correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance (±5%) and long-term reliability under thermal cycling and humidity |
| 600 W peak pulse power (10/1000 μs) | Protects against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 3 surges without degradation |
| AEC-Q101 qualified (HE3 variant) | Validated for automotive powertrain and body electronics applications requiring zero defect field performance |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes voltage overshoot across protected MOSFET gates or microcontroller I/O pins during fast transients |
| Fast response time <1 ns | Clamps before induced transients propagate through PCB traces, preventing latch-up or gate oxide rupture |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Same VWM (94 V), lower PPPM (600 W → 600 W), but SMC package (higher IPPM = 5.2 A) and lower RθJA (30 °C/W vs. 75 °C/W) | Better suited for high-density layouts where axial leads are impractical; requires rework of footprint and thermal relief | Select SMBJ110A when board space is constrained and higher surge repetition rate is required. |
| 1.5KE110A | Same VBR range and DO-15 package, but higher PPPM (1500 W) and larger body (1.25" length); VF = 3.5 V (vs. 5.0 V for P6KE250A+) | Designed for legacy industrial systems needing higher single-pulse margin; incompatible with tape-and-reel automation due to longer lead spacing | Choose 1.5KE110A only if system-level testing confirms need for >600 W single-event immunity. |
Compared with SMBJ110A and 1.5KE110A, P6KE110A-E3/54 offers optimal balance of cost, manufacturability (E3/54 tape-and-reel), and proven field reliability in commercial and automotive-qualified variants-making it ideal for high-volume consumer and industrial power rail protection.

FAQ
What is the maximum clamping voltage of P6KE110A-E3/54 under standard test conditions?
The P6KE110A-E3/54 has a maximum clamping voltage (VC) of 152 V when subjected to its rated peak pulse current of 3.9 A using the 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that downstream components will not experience voltages exceeding 152 V during defined transient events. The clamping performance remains stable across its full operating temperature range of –55 °C to +175 °C.
Is P6KE110A-E3/54 suitable for automotive applications?
Yes, P6KE110A-E3/54 is RoHS-compliant and manufactured to commercial-grade specifications; its AEC-Q101-qualified counterpart is P6KE110AHE3/54. While the E3 suffix itself is not AEC-Q101 certified, the identical die and construction enable drop-in qualification with minimal additional testing. Engineers deploying P6KE110A-E3/54 in non-safety-critical automotive subsystems (e.g., HVAC controls, lighting modules) must verify compliance per their Tier 1 requirements-but the P6KE110A-E3/54 shares all electrical and mechanical specs with the qualified version.
How does the DO-15 package of P6KE110A-E3/54 affect thermal performance?
The DO-15 (DO-204AC) package of P6KE110A-E3/54 provides a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling effective heat transfer to PCB copper pours or chassis-connected leads. Its junction-to-ambient resistance (RθJA) is 75 °C/W under standard conditions-meaning thermal design must allocate ≥25 mm² of 1 oz. copper per lead for sustained 5.0 W power dissipation. This makes P6KE110A-E3/54 well-suited for intermittent surge duty but requires layout attention for continuous high-power operation.
What is the reverse leakage current specification for P6KE110A-E3/54 at its standoff voltage?
At its maximum working voltage (VWM = 94.0 V) and ambient temperature of 25 °C, the P6KE110A-E3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This ultra-low leakage ensures minimal standby power loss in always-on circuits such as automotive body control modules or IoT sensor nodes. Leakage remains below 5.0 μA up to 85 °C, supporting reliable operation in thermally demanding enclosures without compromising battery life.
Can P6KE110A-E3/54 be used in bidirectional configurations?
No, P6KE110A-E3/54 is a unidirectional TVS diode, identified by its cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., P6KE110CA). Using P6KE110A-E3/54 in reverse-biased AC applications would result in forward conduction and catastrophic failure. For bidirectional protection at ~110 V, select P6KE110CA-whose breakdown occurs symmetrically in both directions with VBR = 105–116 V and VC = 177 V at 3.5 A.
