Product details
Overview
P6SMB180CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 180 V standoff voltage (VWM), 207 V breakdown voltage (VBR min), and 600 W peak pulse power (10/1000 μs). It clamps transients to 246 V at 2.4 A peak pulse current and operates from –65 °C to +150 °C, protecting signal lines in industrial sensor interfaces.
For engineers reviewing the P6SMB180CA-E3/52 datasheet, P6SMB180CA-E3/52 pinout, P6SMB180CA-E3/52 application, or P6SMB180CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, 246 V max clamping voltage at rated IPPM, RoHS-compliant matte tin terminations, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device functions as a voltage-clamping transient protector with symmetrical bidirectional avalanche behavior-no polarity marking required. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, while the SMB package supports 600 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle.
Thermal performance is defined by RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), with derating above 25 °C per Figure 2. It meets JESD201 Class 2 whisker resistance and is qualified to AEC-Q101 when ordered with HE3/HM3 suffixes-not applicable to the -E3/52 commercial-grade variant.
Key Specifications

Applications
| Industrial Sensor Signal Protection | Automotive Body Control Module Inputs |
|---|---|
Use Scenario: Protecting analog voltage outputs (0–10 V, 4–20 mA) of pressure/temperature sensors exposed to relay coil flyback and ESD in factory automation cabinets. IC Role / Device Role / Timing Role: Bidirectional clamping TVS placed between signal line and chassis ground, absorbing transients before they reach ADC input or op-amp buffer. Use Value: Limits induced voltage to ≤246 V during 10/1000 μs surges, preventing latch-up or damage to 12-bit SAR ADCs with 15 V absolute max ratings. | Use Scenario: Safeguarding LIN bus inputs and discrete switch sense lines in BCMs subjected to load dump and ISO 7637-2 pulse 1/2a/5a. IC Role / Device Role / Timing Role: Standoff-rated TVS shunting transient energy away from microcontroller GPIO pins and level translators. Use Value: Withstands 180 V continuous battery rail fluctuations and clamps 100 V/500 ms load dump spikes to <250 V, preserving 5 V logic interface integrity. |
| Telecom Line Interface Protection | Consumer Appliance Motor Drive Feedback |
Use Scenario: Shielding RS-485 transceiver data lines (A/B) from lightning-induced surges on outdoor cabling in security or building management systems. IC Role / Device Role / Timing Role: Differential-mode TVS pair (one per line) referenced to local ground, suppressing common-mode transients before receiver input stage. Use Value: 246 V clamping ensures transceiver survival under 1 kV/0.5 Ω IEC 61000-4-5 surge testing, maintaining >250 kbps data integrity post-event. | Use Scenario: Guarding hall-effect rotor position feedback signals in BLDC motor controllers inside washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Low-capacitance TVS on low-voltage analog feedback traces adjacent to high-dI/dt motor phases. Use Value: Sub-100 pF junction capacitance (typ.) avoids signal distortion in 10–100 kHz commutation timing, while 2.4 A IPPM handles MOSFET switching noise coupling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA | Same VWM (180 V), identical SMB package, but 600 W rating with tighter VC = 246 V (same) and lower IPPM tolerance band | No functional difference in clamping performance; differs only in manufacturing lot traceability and screening standards | Select SMBJ180CA if requiring full compliance with MIL-STD-750 test methods or extended temperature screening beyond commercial grade |
| 1.5SMC180CA | Higher package thermal mass (SMC/DO-214AB), same VWM/VC, but 1500 W PPPM and larger 7.11 mm × 6.22 mm footprint | Supports higher surge repetition rates and longer pulse durations due to superior heat dissipation | Choose 1.5SMC180CA where PCB layout allows larger footprint and system-level surge testing exceeds single-event 600 W requirements |
Compared with SMBJ180CA, P6SMB180CA-E3/52 offers identical electrical protection specs at lower cost and broader commercial availability; versus 1.5SMC180CA, it trades surge margin for compactness-ideal for space-constrained consumer and industrial control boards where 600 W coverage suffices.

FAQ
What is the maximum clamping voltage of the P6SMB180CA-E3/52 under rated surge conditions?
The P6SMB180CA-E3/52 has a maximum clamping voltage (VC) of 246 V when subjected to its rated peak pulse current (IPPM) of 2.4 A using the standard 10/1000 μs waveform. This value is guaranteed across the operating temperature range and defines the upper voltage limit imposed on protected circuits during transient events.
Is the P6SMB180CA-E3/52 suitable for automotive applications?
The P6SMB180CA-E3/52 is a commercial-grade part and not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB180CAHE3_B variant (with HE3 suffix), which undergoes stress testing per AEC-Q101. The -E3/52 version may be used in non-safety-critical aftermarket or infotainment subsystems, but design-in requires explicit validation per vehicle OEM requirements.
Does the P6SMB180CA-E3/52 have polarity markings on the package?
No. The P6SMB180CA-E3/52 is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows connection in either orientation between the protected line and ground reference without affecting clamping behavior or electrical performance.
What is the thermal resistance from junction to ambient for the P6SMB180CA-E3/52?
The typical thermal resistance from junction to ambient (RθJA) for the P6SMB180CA-E3/52 is 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes still air convection and forms the basis for derating power dissipation above 25 °C ambient per Figure 2 in the datasheet.
Can the P6SMB180CA-E3/52 be used in place of a unidirectional TVS like P6SMB180A-E3/52?
No-P6SMB180CA-E3/52 and P6SMB180A-E3/52 are electrically distinct: the "CA" suffix denotes bidirectional operation (symmetrical clamping), while "A" indicates unidirectional (cathode-banded, anode-grounded). Substituting one for the other without circuit review risks incorrect clamping polarity, especially in DC-biased signal paths or half-wave rectified supplies.
