Product details
Overview
P6KE150C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode designed for overvoltage protection of sensitive electronics in power and signal lines. It features a 150 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 207 A peak pulse current (IPPM), and clamps transients to ≤375 V at rated surge, with 600 W peak pulse power capability per 10/1000 μs waveform. It is used in automotive sensor interfaces and industrial I/O protection where bidirectional surge immunity is required.
For engineers reviewing the P6KE150C-E3/73 datasheet, P6KE150C-E3/73 pinout, P6KE150C-E3/73 application, or P6KE150C-E3/73 equivalent, key selection criteria include its bi-directional polarity, DO-15 package compatibility, clamping voltage under 375 V at 207 A, and AEC-Q101 qualification for automotive-grade reliability - all critical for robust transient suppression in unidirectional or AC-coupled circuits.
Technical Context
The P6KE150C-E3/73 operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both forward and reverse directions due to its bi-directional construction. Its 10/1000 μs surge rating supports repetitive transients up to 0.01 % duty cycle, and thermal resistance (RθJL = 20 °C/W) enables effective lead-based heat dissipation without heatsinking.
It exhibits low incremental surge resistance and fast response time (<1 ns), enabling protection against ESD, lightning-induced surges, and inductive switching spikes. The device maintains stable clamping performance across -55 °C to +175 °C operating junction temperature, with temperature coefficient of VBR at +0.108 %/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - Guaranteed avalanche onset range; ensures predictable triggering during overvoltage events. |
| VC (Clamping Voltage) | ≤375 V at 207 A IPPM - Peak voltage seen by protected circuit during full-rated surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; validates robustness against common surge threats. |
| ID (Reverse Leakage) | ≤1.0 μA at 128 V - Negligible standby current; avoids loading on high-impedance signal or bias networks. |
| TJ max. | +175 °C - Enables operation in under-hood automotive or high-temperature industrial environments without derating. |
| Package | DO-204AC (DO-15) - Industry-standard axial-leaded package with UL 94 V-0 molded epoxy; compatible with through-hole assembly and manual rework. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body, matte tin-plated leads solderable per J-STD-002. Bi-directional devices have no polarity marking; terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetric) | Transient conduction path | Either lead serves as input/output terminal; identical clamping behavior in both directions - no orientation requirement in PCB layout. |
| Lead 1 / Lead 2 | Thermal and electrical interface | Leads conduct surge current and dissipate heat; RθJL = 20 °C/W allows direct PCB copper pour for thermal relief without additional heatsink. |
Key Features

Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in engine bay or chassis modules from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Standby shunt clamp that remains non-conductive until transient exceeds 128 V, then clamps within nanoseconds to limit voltage to ≤375 V. Use Value: Prevents damage to 16-bit ADC inputs and op-amp front-ends while maintaining signal integrity during normal operation due to <1.0 μA leakage. |
Use Scenario: Safeguarding 24 V DC digital input channels on programmable logic controllers exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Fast-acting voltage limiter placed between field wire and optocoupler input, conducting only during transient events. Use Value: Eliminates need for external series resistors or RC filters while sustaining 600 W surge handling - reduces BOM count and board space. |
| RS-485 Bus Protection | Consumer Appliance Power Supply Clamp |
|
Use Scenario: Bidirectional protection of differential RS-485 data lines (A/B) in building automation systems subject to EFT and lightning-induced coupling. IC Role / Device Role / Timing Role: Symmetrical TVS pair (one per line to GND) or single bi-directional device across differential pair, suppressing common-mode transients. Use Value: Maintains signal eye diagram integrity at 10 Mbps by limiting clamping overshoot to <375 V with sub-nanosecond response - no data corruption. |
Use Scenario: Clamping secondary-side rectifier output in switch-mode power supplies for white goods, preventing MOSFET gate oxide failure during output short-circuit recovery. IC Role / Device Role / Timing Role: Parallel-connected surge suppressor across bulk capacitor or rectifier output, absorbing turn-off spikes from transformer leakage inductance. Use Value: Extends power stage lifetime by limiting transient voltage to 375 V - well below 600 V rating of typical 500 V electrolytic capacitors. |
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 150 V VWM and bi-directional function but in SMB surface-mount package (3.5 mm × 3.5 mm); lower IPPM (123 A) and VC (243 V). | Better suited for space-constrained PCBs; requires reflow assembly and lacks axial-leaded mechanical robustness for high-vibration environments. | Select SMBJ150CA when board area is limited and vibration exposure is low; P6KE150C-E3/73 preferred for through-hole reliability and higher surge margin. |
| 1.5KE150CA | Higher PPPM (1500 W), same DO-15 package and VWM; clamps at ≤260 V (lower VC) but has larger body and higher cost. | Used where surge threat level exceeds IEC 61000-4-5 Level 4 or where tighter clamping is mandatory for low-voltage ICs. | Choose 1.5KE150CA if system-level surge testing requires >600 W margin or VC <260 V; P6KE150C-E3/73 balances cost, size, and standard industrial surge compliance. |
Compared with SMBJ150CA and 1.5KE150CA, the P6KE150C-E3/73 delivers optimal cost-performance trade-off for commercial and automotive applications requiring 600 W surge handling in axial-leaded form - offering proven field reliability, RoHS/AEC-Q101 compliance, and seamless drop-in replacement in legacy DO-15 designs.

FAQ
What does the "C" suffix in P6KE150C-E3/73 indicate?
The "C" suffix denotes bi-directional polarity - meaning the P6KE150C-E3/73 provides symmetrical transient suppression in both forward and reverse directions, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity. This makes it ideal for AC lines, differential signals, or floating nodes where polarity is undefined. Unlike uni-directional variants (e.g., P6KE150A), the P6KE150C-E3/73 has no cathode marking and functions identically across either lead orientation.
Is P6KE150C-E3/73 AEC-Q101 qualified?
Yes, the P6KE150C-E3/73 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P6KE150CHE3/73). The E3/73 variant is RoHS-compliant and commercial-grade; however, the HE3 suffix explicitly indicates AEC-Q101 qualification per Vishay's ordering nomenclature. For automotive applications requiring formal qualification, specify P6KE150CHE3/73 - the P6KE150C-E3/73 itself meets all electrical and mechanical specs but carries commercial-grade certification unless HE3 is included.
What is the maximum clamping voltage of P6KE150C-E3/73 at rated surge current?
The maximum clamping voltage (VC) of the P6KE150C-E3/73 is 375 V at 207 A peak pulse current (IPPM), measured under the standard 10/1000 μs double-exponential waveform. This value represents the worst-case voltage imposed on the protected circuit during full-rated surge, and is guaranteed across the operating temperature range. It directly determines whether downstream components - such as 300 V-rated capacitors or 400 V MOSFETs - remain within safe operating limits when the P6KE150C-E3/73 activates.
Can P6KE150C-E3/73 be used in place of P6KE150A?
No - P6KE150C-E3/73 and P6KE150A are not interchangeable without circuit review. The P6KE150A is uni-directional (cathode-marked), conducts only in reverse bias, and has different leakage and forward voltage behavior. Substituting the bi-directional P6KE150C-E3/73 in a uni-directional design may cause unintended conduction during normal forward-biased operation. Always verify polarity requirements, VF constraints, and system grounding before replacing P6KE150A with P6KE150C-E3/73.
What is the thermal resistance and power derating behavior of P6KE150C-E3/73?
The P6KE150C-E3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Its 5.0 W steady-state power dissipation (PD) is rated at TL = 75 °C on an infinite heatsink; above this lead temperature, power must be linearly derated to zero at 175 °C. For example, at TL = 100 °C, allowable PD drops to ~3.3 W. This derating curve (Fig. 5 in Vishay doc #88369) ensures safe operation under sustained ambient heating while preserving surge capability.
