Overview
P6SMB180AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in 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 (10/1000 µs waveform). It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients and ESD.
For engineers reviewing the P6SMB180AHE3_A/H datasheet, P6SMB180AHE3_A/H pinout, P6SMB180AHE3_A/H application, or P6SMB180AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C maximum junction temperature, low incremental surge resistance, and RoHS-compliant matte tin-plated terminals suitable for J-STD-002 soldering.
Technical Context
This TVS operates as a unidirectional clamping device with cathode-band polarity marking, leveraging a glass-passivated silicon junction for stable breakdown behavior and fast response (<1 ns). Its thermal resistance (RθJA = 100 °C/W) and RθJL = 20 °C/W support reliable operation under repetitive surge conditions when mounted on 5.0 mm × 5.0 mm copper pads.
The device complies with MSL Level 1 per J-STD-020 (peak reflow ≤260 °C), features UL 94 V-0 molding compound, and delivers consistent clamping performance across -65 °C to +150 °C operating range - critical for under-hood automotive modules and industrial motor drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180A | Same VWM (154 V), but lower PPPM (400 W) and higher VC (265 V); SMA package (smaller footprint, higher RθJA). | Limited to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4. | Select only where space constraints outweigh surge margin requirements and thermal budget permits higher junction rise. |
| SMCJ180A | Same VWM/VC, but higher PPPM (1500 W); larger SMC (DO-214AB) package with lower RθJA (50 °C/W). | Better thermal performance and surge endurance, but requires 2× PCB area and different land pattern. | Choose when system-level surge testing exceeds 600 W or sustained ambient temperatures exceed 105 °C. |
Compared with SMAJ180A, P6SMB180AHE3_A/H offers 50% higher surge power headroom and tighter clamping; versus SMCJ180A, it trades 60% smaller board area for reduced thermal margin - making it optimal for space-constrained AEC-Q101 automotive modules where 600 W is sufficient.

FAQ
What is the clamping voltage of P6SMB180AHE3_A/H at its rated peak pulse current?
The P6SMB180AHE3_A/H has a maximum clamping voltage (VC) of 246 V at a peak pulse current (IPPM) of 2.4 A, measured using the standard 10/1000 µs double-exponential waveform. This value is guaranteed per the Vishay datasheet revision 09-Jan-2024 and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB180AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is P6SMB180AHE3_A/H qualified for automotive applications?
Yes, P6SMB180AHE3_A/H is AEC-Q101 qualified, as indicated by the "HE3" suffix and confirmed in the Vishay P6SMB datasheet. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life - meeting requirements for under-hood and body-control module deployments. The P6SMB180AHE3_A/H is explicitly listed in Vishay's AEC-Q101 qualified product matrix for the P6SMB family.
What does the "_A/H" suffix in P6SMB180AHE3_A/H signify?
The "_A" denotes unidirectional polarity, and "/H" specifies packaging in 7-inch plastic tape-and-reel format with 750 units per reel. The "HE3" portion confirms RoHS-compliant construction and AEC-Q101 qualification. This full suffix distinguishes P6SMB180AHE3_A/H from commercial-grade (E3/M3) or non-automotive variants, ensuring traceability to qualified manufacturing lots. The P6SMB180AHE3_A/H ordering code aligns with Vishay's standardized nomenclature for automotive-grade SMB TVS diodes.
How does P6SMB180AHE3_A/H compare to bidirectional versions like P6SMB180CA?
P6SMB180AHE3_A/H is unidirectional with cathode-band marking and conducts only in reverse breakdown, whereas P6SMB180CA is bidirectional and symmetrical - clamping in both polarities. The unidirectional P6SMB180AHE3_A/H offers lower leakage current (<1 µA at VWM) and is preferred for DC rail protection, while the bidirectional variant suits AC-coupled signal lines. Both share identical VWM, VC, and PPPM, but P6SMB180AHE3_A/H cannot replace P6SMB180CA in AC applications without circuit redesign.
What is the thermal resistance of P6SMB180AHE3_A/H, and how does it affect layout design?
P6SMB180AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 5.0 mm × 5.0 mm copper pads per terminal. This value assumes no additional heatsinking; layout must provide adequate copper area and avoid thermal isolation. For continuous power dissipation above 100 mW, thermal simulation is advised. The P6SMB180AHE3_A/H datasheet specifies derating curves showing 1% power reduction per 1 °C above 25 °C ambient.
