Product details
Overview
P6SMB180CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 154 V standoff voltage (VWM), 171–189 V breakdown voltage (VBR) at 1 mA, 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB180CAHE3_A/H datasheet, P6SMB180CAHE3_A/H pinout, P6SMB180CAHE3_A/H application, or P6SMB180CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, thermal resistance (RθJA = 100 °C/W), and compliance with IEC 61000-4-2/4-5 surge immunity requirements.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity - critical for protecting AC-coupled or differential signal paths. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 moisture sensitivity, supporting lead-free reflow up to 260 °C peak. The HE3 suffix confirms RoHS-compliance and AEC-Q101 qualification, making it suitable for automotive under-hood and infotainment applications requiring long-term reliability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180CA | Same VWM (154 V), lower PPPM (400 W), SMA package (larger RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for IEC 61000-4-5 Level 4 compliance | Select when board space allows larger SMA footprint and surge requirements are ≤400 W. |
| SMCJ180CA | Same VWM (154 V), higher PPPM (1500 W), SMC package (RθJA = 50 °C/W) | Overqualified for 600 W needs; requires larger PCB area and higher assembly cost | Choose only when system-level surge testing exceeds 600 W or thermal constraints demand lower RθJA. |
Compared with SMAJ180CA and SMCJ180CA, P6SMB180CAHE3_A/H delivers optimal balance of 600 W surge handling, SMB footprint efficiency, and AEC-Q101 qualification - making it the preferred choice for space-constrained automotive and industrial designs requiring validated reliability without over-engineering.

FAQ
What is the clamping voltage of P6SMB180CAHE3_A/H at its rated peak pulse current?
The P6SMB180CAHE3_A/H has a maximum clamping voltage (VC) of 246 V at its specified peak pulse current (IPPM) of 2.4 A under a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuits during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6SMB180CAHE3_A/H suitable for automotive applications?
Yes, P6SMB180CAHE3_A/H is AEC-Q101 qualified (indicated by the HE3 suffix) and tested for temperature cycling, high-temperature reverse bias, and ESD per automotive reliability standards. It is approved for use in engine control units, body electronics, and ADAS sensor interfaces where sustained operation from −65 °C to +150 °C and surge immunity are required.
How does the bidirectional design of P6SMB180CAHE3_A/H affect circuit layout?
The bidirectional design of P6SMB180CAHE3_A/H eliminates polarity marking - both terminals are functionally identical, allowing placement across any two-point node without orientation concerns. This simplifies layout on differential lines (e.g., CAN, RS-485) and AC-coupled paths, reducing routing constraints and eliminating risk of reverse installation during assembly.
What is the thermal resistance of P6SMB180CAHE3_A/H, and how does it impact PCB design?
P6SMB180CAHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under 5.0 W steady-state dissipation, designers must allocate adequate copper area and avoid excessive local heating - especially important in high-density automotive modules.
Does P6SMB180CAHE3_A/H meet industry surge immunity standards?
Yes, P6SMB180CAHE3_A/H is characterized for 600 W peak pulse power with a 10/1000 μs waveform, aligning with IEC 61000-4-5 Level 3 (1 kV line-to-ground, 2 kV line-to-line) and ISO 7637-2 Pulse 1/2/3a/b test profiles. Its 246 V clamping voltage ensures protected circuits remain within safe operating zones during standardized surge events.
