Product details
Overview
P6SMB150CAHE3_B/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 150 V standoff voltage (VWM), 207 V maximum clamping voltage (VC) at 2.9 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the P6SMB150CAHE3_B/I datasheet, P6SMB150CAHE3_B/I pinout, P6SMB150CAHE3_B/I application, or P6SMB150CAHE3_B/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports consistent clamping under repetitive transients.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (260 °C peak reflow), making it suitable for high-reliability automotive and industrial reflow processes. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification per revision B, with tape-and-reel packaging (I = 13" reel, 3200 units).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse voltage before clamping initiates; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 207 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capacity under standardized surge waveform; enables robust ESD/Lightning-level immunity. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Minimal standby current draw; critical for low-power sensor and battery-backed systems. |
| TJ max. | 150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial ambient environments. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; enables effective heat dissipation through PCB copper pads without external heatsink. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. No polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode / Anode (symmetrical) | Bidirectional terminal pair | Identical electrical behavior in either direction; no cathode band marking required - simplifies layout and eliminates polarity error risk. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified (HE3_B) | Validated for automotive applications including engine control, ADAS sensors, and infotainment power rails. |
| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 surge events up to 4 kV (line-earth) when properly mounted on 5 mm × 5 mm copper pads. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; reduces manufacturing complexity. |
| Glass-passivated junction | Ensures long-term stability of VBR and low parametric drift over temperature and lifetime. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage exposure to protected ICs - critical for 3.3 V/5 V logic and analog front-ends. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150CA | Same VWM (128 V) and VC (207 V), but lower PPPM (400 W); SMA package (DO-214AC), larger RθJA (150 °C/W). | Limited to lower-energy transients; less suitable for automotive load-dump where 600 W margin is required. | Select P6SMB150CAHE3_B/I when higher pulse power headroom and AEC-Q101 qualification are mandatory. |
| SMCJ150CA | Higher PPPM (1500 W), same VWM/VC, but larger SMC (DO-214AB) package; not AEC-Q101 qualified in standard grade. | Over-specified for space-constrained PCBs; requires redesign for pad layout and assembly tooling. | Choose P6SMB150CAHE3_B/I for footprint-constrained automotive modules needing validated qualification and optimal power density. |
Compared with SMAJ150CA and SMCJ150CA, the P6SMB150CAHE3_B/I delivers balanced performance: 600 W pulse handling in compact SMB form factor, AEC-Q101 certification out-of-box, and optimized thermal path for sustained reliability in high-temperature environments - making it the preferred choice for next-gen automotive and industrial edge nodes.

FAQ
What does the "CA" suffix indicate in P6SMB150CAHE3_B/I?
The "CA" suffix denotes a bidirectional configuration: the P6SMB150CAHE3_B/I provides symmetrical clamping in both polarities, eliminating the need for polarity-aware placement. This is essential for protecting AC-coupled signals, differential buses like RS-485 or CAN, and ungrounded power rails where voltage reversal may occur during transients.
Is P6SMB150CAHE3_B/I qualified for automotive use?
Yes - the "HE3_B" suffix certifies that the P6SMB150CAHE3_B/I is RoHS-compliant and AEC-Q101 qualified per revision B. It has passed stress tests including temperature cycling, humidity bias, and high-temperature operating life, making it suitable for under-hood and cabin applications such as ADAS camera modules and body control units.
What is the maximum clamping voltage of P6SMB150CAHE3_B/I and under what test condition?
The P6SMB150CAHE3_B/I has a maximum clamping voltage (VC) of 207 V, measured at a peak pulse current (IPPM) of 2.9 A using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the worst-case overvoltage imposed on protected circuitry during surge events.
How does the SMB (DO-214AA) package of P6SMB150CAHE3_B/I compare thermally to larger packages?
The SMB package of P6SMB150CAHE3_B/I achieves a junction-to-lead thermal resistance (RθJL) of 20 °C/W - significantly lower than typical RθJA values - enabling efficient heat transfer into PCB copper pads. When mounted on 0.2" × 0.2" (5 mm × 5 mm) copper areas, it sustains 600 W pulses without exceeding 150 °C junction temperature, unlike larger packages relying solely on ambient convection.
Can P6SMB150CAHE3_B/I be used in place of unidirectional TVS diodes?
No - the P6SMB150CAHE3_B/I is strictly bidirectional and lacks polarity marking; substituting it for a unidirectional part (e.g., P6SMB150A) would compromise forward conduction path integrity in DC-biased circuits. It must only replace other CA-suffix variants, and layout must ensure symmetrical routing to preserve its bidirectional clamping behavior.
