Product details
Overview
P6SMB180A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 180 V standoff voltage (VWM), 246 V clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects sensitive ICs, MOSFETs, and sensor signal lines against inductive switching transients and lightning-induced surges in industrial and telecom power rails.
For engineers reviewing the P6SMB180A-E3/52 datasheet, P6SMB180A-E3/52 pinout, P6SMB180A-E3/52 application, or P6SMB180A-E3/52 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant commercial-grade construction, and real-world ESD/transient protection design context - all confirmed from Vishay's official P6SMB Series specification document (Rev. 09-Jan-2024, Doc. #88370).
Technical Context
This TVS diode operates as a unidirectional clamping device with a cathode-band-marked polarity. Its silicon junction is glass passivated for stable leakage and robust surge handling, and it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
It delivers 600 W peak pulse power under standardized 10/1000 μs waveform testing at 0.01 % duty cycle, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to 150 °C junction temperature in properly laid-out PCB environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 154 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 171–189 V at 1 mA - Measured breakdown range ensures consistent turn-on threshold across production lots. |
| VC (Clamping) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during worst-case transient; critical for downstream component voltage rating selection. |
| PPPM | 600 W - Sustains 10/1000 μs surge energy without failure; enables protection against IEC 61000-4-5 Level 4 surges when properly mounted. |
| ID (Leakage) | 1.0 μA max at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; requires thermal pad layout per Vishay's 0.2" × 0.2" copper recommendation for full power rating. |
| RθJA | 100 °C/W - Thermal resistance dictates required board copper area and airflow for sustained surge duty cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180A | Same VWM (154 V), VC = 246 V, but lower PPPM (400 W); SMA package (DO-214AC), higher RθJA (150 °C/W). | Limited to lower-energy transients; less suitable for repeated 600 W surges or high-temperature ambient designs. | Select when cost or footprint constraints favor SMA, and surge energy remains ≤400 W. |
| SMCJ180A | Same VWM/VC ratings, but higher PPPM (1500 W); larger SMC package (DO-214AB), lower RθJA (35 °C/W). | Better thermal performance and surge endurance; requires larger PCB area and higher mounting force. | Choose for mission-critical 48 V power rails where single-event survivability >600 W is mandated. |
Compared with P6SMB180A-E3/52, SMAJ180A trades peak power and thermal capability for smaller size, while SMCJ180A provides superior surge handling at the cost of footprint and assembly complexity - making P6SMB180A-E3/52 the balanced choice for space-constrained 600 W protection in commercial industrial systems.

FAQ
What is the clamping voltage of P6SMB180A-E3/52 and how is it measured?
The clamping voltage (VC) of P6SMB180A-E3/52 is 246 V, measured at a peak pulse current (IPPM) of 2.4 A using the standardized 10/1000 μs double-exponential waveform. This value represents the maximum voltage that appears across the device during a surge event and is critical for ensuring protected components remain within their absolute maximum voltage ratings. The test condition is defined in Vishay's P6SMB datasheet (Doc. #88370, Rev. 09-Jan-2024) and applies at TA = 25 °C with specified PCB mounting.
Is P6SMB180A-E3/52 suitable for automotive applications?
P6SMB180A-E3/52 is a commercial-grade, RoHS-compliant part (E3 suffix) and is not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB180AHE3_B variant (with HE3 suffix and revision code B), which is explicitly AEC-Q101 qualified and tested per automotive reliability standards. Engineers must select the HE3 or HM3 version - not P6SMB180A-E3/52 - for under-hood or safety-critical automotive deployments.
What is the thermal resistance and how does it affect PCB layout for P6SMB180A-E3/52?
P6SMB180A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. To achieve rated 600 W peak pulse power, Vishay specifies mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Reducing pad area increases thermal impedance, causing higher junction temperatures and potential derating of surge capability - especially under repetitive surge conditions.
Does P6SMB180A-E3/52 have bidirectional capability?
No, P6SMB180A-E3/52 is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). It conducts only in reverse bias above VBR and blocks forward current like a standard diode. For bidirectional protection (e.g., AC lines or differential buses), the equivalent part is P6SMB180CA-E3/52, which has symmetrical clamping in both directions and no polarity marking.
What is the maximum reverse leakage current for P6SMB180A-E3/52 at its stand-off voltage?
The maximum reverse leakage current (ID) for P6SMB180A-E3/52 is 1.0 μA at its rated stand-off voltage (VWM) of 154 V and TA = 25 °C. This ultra-low leakage ensures minimal impact on high-impedance sensing nodes and battery-powered circuits, preserving accuracy and extending operational life - a key advantage over higher-leakage alternatives in precision analog or low-power IoT sensor interfaces.
