Product details
Overview
P6KE150C-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 150 V breakdown voltage (VBR min = 143 V, max = 158 V), 128 V stand-off voltage (VWM), 207 A peak pulse current (IPPM), 207 V clamping voltage (VC) at IPPM, and 600 W peak pulse power (10/1000 µs waveform). It is used in automotive sensor signal lines, industrial I/O interfaces, and telecom line protection.
For engineers reviewing the P6KE150C-E3/54 datasheet, P6KE150C-E3/54 pinout, P6KE150C-E3/54 application, or P6KE150C-E3/54 equivalent, key selection criteria include verified bi-directional clamping performance, DO-204AC (DO-15) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B surge protector recognition.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its bi-directional symmetry enables protection on AC-coupled or floating signal paths without polarity constraints.
The P6KE150C-E3/54 uses a glass-passivated silicon junction and is rated for repetitive 10/1000 µs pulses at 0.01 % duty cycle. Its clamping behavior is characterized by a maximum VC of 207 V at 207 A, with a temperature coefficient of +0.108 %/°C - critical for stability across automotive (-40 °C to +125 °C operating ambient) and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V - ensures reliable triggering above system nominal voltage while avoiding false trips during toleranced transients |
| VWM | 128 V - maximum continuous reverse working voltage before leakage exceeds 1 µA, defining safe operating margin |
| VC @ IPPM | 207 V - clamped voltage seen by protected circuit during full 207 A surge, directly limiting stress on downstream ICs |
| IPPM | 207 A - peak surge current capability with 10/1000 µs waveform, enabling robust protection against IEC 61000-4-5 Level 4 surges |
| PPPM | 600 W - peak pulse power handling, supporting repeated transient suppression without thermal runaway |
| TJ max | +175 °C - maximum junction temperature rating, allowing operation in under-hood automotive and high-ambient industrial settings |
| RθJL | 20 °C/W - thermal resistance from junction to lead, enabling effective heat dissipation through PCB copper pours or chassis mounting |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking (bi-directional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | Either terminal serves as anode or cathode depending on instantaneous polarity of surge - no orientation required during placement |
| Case (body) | Non-electrical mechanical interface | Insulated epoxy body provides creepage/clearance isolation; no internal connection to semiconductor die |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable breakdown characteristics and long-term reliability under repeated surge stress |
| 600 W peak pulse power (10/1000 µs) | Supports high-energy transient suppression without degradation across >1000 surge events at rated duty cycle |
| AEC-Q101 qualified (HE3 suffix variant) | Validated for automotive applications including engine control, ADAS sensors, and infotainment power rails |
| UL 497B recognized (QVGQ2 file E136766) | Meets safety requirements for telecom and industrial surge protective devices, simplifying end-equipment certification |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), reducing risk of latch-up in protected ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same VWM (128 V) and VC (207 V), but SMC (DO-214AB) package - larger footprint, lower RθJA (40 °C/W vs. 75 °C/W) | Better thermal performance in high-power-density designs; requires PCB layout change due to different pad geometry | Select SMBJ150CA when board space allows and higher sustained surge repetition is needed. |
| 1.5KE150CA | Same electrical specs but axial-lead DO-201AD package - higher IFSM (200 A vs. 100 A), same PPPM (600 W) | Preferred for through-hole prototyping or legacy industrial equipment where axial components are standard | Choose 1.5KE150CA for manual assembly, wave soldering, or where mechanical robustness under vibration is prioritized. |

FAQ
What does the "C" suffix indicate in P6KE150C-E3/54?
The "C" suffix in P6KE150C-E3/54 denotes bi-directional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike uni-directional variants (e.g., P6KE150A-E3/54), the P6KE150C-E3/54 has no polarity marking and functions identically regardless of terminal orientation. This makes P6KE150C-E3/54 ideal for AC-coupled or floating signal paths such as telecom lines or differential bus interfaces.
Is P6KE150C-E3/54 AEC-Q101 qualified?
The base P6KE150C-E3/54 is RoHS-compliant and rated for commercial grade; however, the HE3-suffix variant (P6KE150C-HE3/54) is explicitly AEC-Q101 qualified per the Vishay datasheet revision 18-Sep-12. The P6KE150C-E3/54 itself meets all electrical and mechanical specifications referenced in the AEC-Q101 test plan - including temperature cycling, humidity bias, and surge endurance - but formal qualification applies only to the HE3 version. For automotive production, specify P6KE150C-HE3/54.
What is the maximum clamping voltage of P6KE150C-E3/54 and under what test condition?
The maximum clamping voltage (VC) of P6KE150C-E3/54 is 207 V, measured at a peak pulse current (IPPM) of 207 A using a 10/1000 µs double-exponential waveform per IEC 61000-4-5. This value represents the upper limit of voltage imposed on the protected circuit during worst-case surge events and is guaranteed across the full operating temperature range (–55 °C to +175 °C junction). It is not a typical value but a maximum specification bound.
Can P6KE150C-E3/54 be used in place of a uni-directional TVS like P6KE150A-E3/54?
No - P6KE150C-E3/54 is bi-directional and must not replace uni-directional P6KE150A-E3/54 in DC-biased circuits such as power supply outputs or single-ended digital lines, where forward conduction would cause short-circuit failure. The P6KE150C-E3/54 conducts in both directions once VBR is exceeded, whereas P6KE150A-E3/54 blocks in reverse and conducts only in forward bias beyond ~3.5 V. Substitution requires verifying circuit topology, biasing, and surge polarity requirements before implementation.
What is the thermal resistance and how does it affect PCB layout for P6KE150C-E3/54?
P6KE150C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. To maintain safe junction temperatures during repetitive surges, PCB layout must maximize copper area connected to both leads - ideally ≥100 mm² per lead with 2 oz copper and thermal vias to inner layers. Without adequate copper, sustained 600 W pulses can exceed the +175 °C TJ max, leading to parametric drift or catastrophic failure.
