Product details
Overview
P6SMB150CAHE3_A/I 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 150 V standoff voltage (VWM), 165 V minimum breakdown voltage (VBR), 207 V maximum clamping voltage (VC) at 2.9 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 interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB150CAHE3_A/I datasheet, P6SMB150CAHE3_A/I pinout, P6SMB150CAHE3_A/I application, or P6SMB150CAHE3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, SMB (DO-214AA) package thermal performance, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping behavior above ±165 V breakdown threshold with ≤207 V clamping voltage at rated IPPM. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for protecting sensitive analog and digital inputs against ESD and lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and exhibits low incremental surge resistance, enabling robust energy absorption without thermal runaway. Its MSL Level 1 rating (J-STD-020) and matte tin-plated leads support lead-free reflow soldering at 260 °C peak, making it suitable for high-reliability automated assembly in automotive and industrial control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 150 V - Maximum continuous reverse voltage before clamping begins; defines operating margin for protected circuitry. |
| VBR (Breakdown Voltage) | 165–185 V - Minimum voltage at which device enters avalanche conduction; ensures reliable triggering during transients. |
| VC (Clamping Voltage) | 207 V at 2.9 A - Peak voltage seen by downstream components during 10/1000 μs surge; determines protection level. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity under standardized 10/1000 μs waveform; supports IEC 61000-4-5 Level 3/4 compliance. |
| ID (Reverse Leakage) | ≤1.0 μA at 150 V - Minimal standby current; avoids loading of high-impedance signal paths or battery-powered circuits. |
| TJ max. | 150 °C - Maximum junction temperature; enables operation in under-hood automotive or enclosed industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same SMB package, 150 V VWM, but lower PPPM (600 W same), higher VC (219 V at 2.7 A); no AEC-Q101 qualification. | Commercial-grade only; not validated for automotive temperature cycling or humidity testing. | Select when AEC-Q101 is not required and cost optimization is prioritized over automotive reliability documentation. |
| 1.5KE150CA | Through-hole DO-15 package, same 150 V VWM and bidirectional function, but larger footprint and lower thermal efficiency (RθJA ≈ 150 °C/W vs. 100 °C/W). | Not suitable for high-density SMT layouts; requires manual or wave soldering; less compatible with automated test handling. | Choose only if legacy through-hole design constraints prevent SMB adoption or if board-level mechanical robustness outweighs size penalty. |
Compared with SMBJ150CA and 1.5KE150CA, P6SMB150CAHE3_A/I delivers automotive-grade reliability in a compact SMT package with superior thermal resistance and verified surge endurance - making it optimal for new designs targeting ISO 16750-2 and AEC-Q200-compliant systems.

FAQ
What does the "CA" suffix indicate in P6SMB150CAHE3_A/I?
The "CA" suffix denotes that P6SMB150CAHE3_A/I is a bidirectional Transient Voltage Suppressor. Unlike unidirectional variants (e.g., P6SMB150A), this version provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, differential buses like RS-485 or CAN, and floating power rails where polarity reversal may occur during surge events.
Is P6SMB150CAHE3_A/I qualified for automotive use?
Yes, P6SMB150CAHE3_A/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and Vishay's ordering code documentation. It has undergone full stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D, making it suitable for under-hood and cabin electronics in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of P6SMB150CAHE3_A/I and how is it measured?
The maximum clamping voltage (VC) of P6SMB150CAHE3_A/I is 207 V, measured at a peak pulse current (IPPM) of 2.9 A using the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value represents the highest voltage imposed on protected circuitry during worst-case surge conditions and is guaranteed across the full operating temperature range.
How does the SMB (DO-214AA) package of P6SMB150CAHE3_A/I compare thermally to larger packages like DO-15?
P6SMB150CAHE3_A/I in the SMB (DO-214AA) package has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, significantly lower than the ~150 °C/W of through-hole DO-15 packages like 1.5KE150CA. This improved thermal performance allows higher sustained power dissipation in dense SMT layouts and better reliability in thermally constrained automotive and industrial enclosures.
Can P6SMB150CAHE3_A/I be used in place of a unidirectional TVS like P6SMB150A?
No - P6SMB150CAHE3_A/I is bidirectional and lacks polarity marking, whereas P6SMB150A is unidirectional with a cathode band. Substituting them requires verifying circuit topology: P6SMB150CAHE3_A/I is appropriate for AC or floating nodes, but P6SMB150A must be used where DC bias polarity is fixed and forward conduction must be blocked. Interchange alters clamping behavior and may compromise protection.
