Product details
Overview
P6SMB150CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 150 V standoff voltage (VWM), 165 V minimum breakdown voltage (VBR), 207 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line cards.
For engineers reviewing the P6SMB150CA-E3/52 datasheet, P6SMB150CA-E3/52 pinout, P6SMB150CA-E3/52 application, or P6SMB150CA-E3/52 equivalent, key selection criteria include bidirectional clamping symmetry, low thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification eligibility via HE3 suffix variants, and SMB (DO-214AA) package compatibility with automated SMT assembly.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity - critical for AC-coupled or floating signal paths. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), while the low incremental surge resistance minimizes voltage overshoot during high-di/dt events.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; its thermal resistance (RθJA = 100 °C/W on 0.2" × 0.2" copper pads) supports reliable operation in compact, convection-cooled layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 150 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown) | 165–183 V at 1 mA - Voltage at which device transitions from high-impedance to low-impedance clamping state. |
| VC (Clamping) | 207 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream ICs. |
| PPPM | 600 W - Peak transient energy absorption capacity under standardized 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 3 surges. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; optimized for pick-and-place and reflow compatibility. |
| Leakage (ID) | ≤1.0 μA at 150 V - Minimal standby current draw; preserves battery life and avoids false triggering in high-impedance nodes. |
| Temp Range | −65 °C to +150 °C - Full operational range supports under-hood automotive, industrial control, and outdoor telecom environments. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability requirements. Bidirectional construction has no polarity marking - terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Both terminals serve as interchangeable surge current entry/exit points; no cathode band marking required for bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for polarity-aware layout in AC or differential signal lines. |
| 600 W peak pulse power | Withstands 10/1000 μs transients up to 2.9 A - meets IEC 61000-4-5 surge immunity requirements for industrial and telecom equipment. |
| Glass passivated junction | Stable leakage (<1 μA) and long-term reliability under thermal cycling - critical for automotive and extended-life embedded systems. |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without preconditioning - reduces manufacturing complexity and cost. |
| AEC-Q101 qualification path | HE3/HM3 suffix variants available - enables direct use in automotive ECUs, ADAS sensors, and body electronics. |

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 SMB package, identical VWM/VBR/VC specs, but rated for 600 W with tighter VC tolerance (±5 % vs ±10 % for P6SMB series). | Preferred where tighter clamping consistency is required across production lots, e.g., medical-grade power supplies. | Select SMBJ150CA when statistical clamping variation must be minimized; P6SMB150CA-E3/52 offers broader cost-effective volume availability. |
| 1.5SMC150CA | Larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), same electrical specs, higher RθJA (70 °C/W) due to larger thermal mass. | Better suited for high-reliability, low-volume applications where board space permits and manual rework is acceptable. | Choose 1.5SMC150CA only if existing layout accommodates SMC footprint; P6SMB150CA-E3/52 delivers identical protection in 30 % smaller area. |
Compared with SMBJ150CA and 1.5SMC150CA, P6SMB150CA-E3/52 provides optimal balance of SMB footprint efficiency, AEC-Q101 upgrade path, and commercial-grade cost structure - making it ideal for high-volume automotive and industrial designs requiring proven surge resilience without over-engineering.

FAQ
What is the clamping voltage of P6SMB150CA-E3/52 at its rated peak pulse current?
The P6SMB150CA-E3/52 has a maximum clamping voltage (VC) of 207 V at a peak pulse current (IPPM) of 2.9 A under a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6SMB150CA-E3/52 suitable for automotive applications?
P6SMB150CA-E3/52 itself is commercial-grade (RoHS-compliant, MSL Level 1), but Vishay offers AEC-Q101 qualified variants under HE3/HM3 suffixes (e.g., P6SMB150CAHE3_B). The P6SMB150CA-E3/52 shares identical electrical characteristics and SMB package with those qualified versions, allowing seamless migration to automotive-grade builds when needed - no layout change required.
How does the bidirectional design of P6SMB150CA-E3/52 affect PCB layout?
The bidirectional construction of P6SMB150CA-E3/52 eliminates polarity sensitivity: no cathode band marking exists, and either terminal may connect to line or ground. This simplifies layout for AC-coupled interfaces like RS-485, CAN, or Ethernet, removes orientation verification during assembly, and avoids costly rework from reversed placement - especially valuable in high-speed automated SMT lines.
What is the thermal resistance of P6SMB150CA-E3/52, and how does it impact power dissipation?
P6SMB150CA-E3/52 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 100 °C/W on 0.2" × 0.2" copper pads. This means under sustained 5.0 W power dissipation (PD), junction temperature rise is ~100 °C above ambient - confirming suitability for intermittent surge duty (0.01 % duty cycle), not continuous operation. Derating curves in Figure 2 must be applied for elevated ambient temperatures.
Can P6SMB150CA-E3/52 replace unidirectional TVS diodes in existing designs?
No - P6SMB150CA-E3/52 is strictly bidirectional and lacks polarity marking; substituting it for a unidirectional part (e.g., P6SMB150A) would compromise protection on DC-biased lines, as forward conduction could short the rail during normal operation. Always verify circuit topology: use P6SMB150CA-E3/52 only where symmetrical clamping is required, such as AC signal paths or floating grounds.
