Product details
Overview
P6SMB22CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 22 V standoff voltage (VWM), 23.1 V minimum breakdown voltage (VBR), and 30.6 V maximum clamping voltage (VC) at 19.6 A peak pulse current (IPPM), designed to protect signal lines and power rails in automotive and industrial electronics against ESD and inductive switching transients.
For engineers reviewing the P6SMB22CAHE3_B/H datasheet, P6SMB22CAHE3_B/H pinout, P6SMB22CAHE3_B/H application, or P6SMB22CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 600 W peak pulse power rating with 10/1000 μs waveform, low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin-plated terminals suitable for J-STD-002 soldering.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction, enabling suppression of both positive and negative polarity transients without polarity sensitivity. It features glass-passivated junctions for stable leakage performance and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
The P6SMB22CAHE3_B/H delivers 600 W peak pulse power handling under standardized 10/1000 μs surge conditions at 0.01 % duty cycle, with clamping voltage tightly controlled at ≤30.6 V up to 19.6 A, ensuring robust protection margin for 24 V nominal systems. Its 20 °C/W junction-to-lead thermal resistance supports reliable power dissipation during repetitive surges when mounted on recommended 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 22 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating window for 24 V rail protection. |
| VBR (Breakdown Voltage) | 20.9–23.1 V at 1 mA - Voltage at which device transitions from high-impedance to low-impedance clamping state; ensures predictable turn-on threshold. |
| VC (Clamping Voltage) | 30.6 V at IPPM = 19.6 A - Maximum voltage seen by protected circuit during worst-case 10/1000 μs surge; provides 27 % overvoltage margin above 24 V system. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capacity under standard 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 3 surges. |
| RθJL (Junction-to-Lead Thermal Resistance) | 20 °C/W - Enables efficient heat transfer from silicon die to PCB copper pads; critical for reliability under repeated surge events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22CA | Same SMB package, 22 V VWM, but lower PPPM (400 W) and higher VC (35.5 V at 11.5 A); not AEC-Q101 qualified. | Limited to commercial-grade consumer/industrial use; insufficient for automotive under-hood surge requirements. | Select when cost sensitivity outweighs automotive qualification and 600 W surge headroom. |
| SMCJ22CA | Higher-power SMC (DO-214AB) package, same 22 V VWM, 1500 W PPPM, lower VC (36.5 V at 41.3 A); AEC-Q101 available in HE3 variant. | Requires larger PCB footprint (7.11 × 6.22 mm vs. 4.57 × 3.94 mm) and higher mounting pad area. | Choose when system-level surge threat exceeds 600 W or when design allows larger footprint for extended lifetime under repetitive stress. |
Compared with SMAJ22CA and SMCJ22CA, the P6SMB22CAHE3_B/H uniquely balances AEC-Q101 compliance, 600 W surge capability, and SMB footprint-making it optimal for space-constrained automotive modules where qualification and moderate surge levels coexist.

FAQ
What does the "CA" suffix indicate in P6SMB22CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB22CAHE3_B/H provides symmetrical clamping for both positive- and negative-polarity transients without polarity dependence. This eliminates the need for orientation-aware placement and simplifies layout for AC-coupled or floating signal paths, unlike unidirectional variants (e.g., P6SMB22A) that require cathode alignment.
Is P6SMB22CAHE3_B/H suitable for automotive applications?
Yes, the P6SMB22CAHE3_B/H is AEC-Q101 qualified, as confirmed by its "HE3" and "_B" suffixes indicating RoHS-compliant and automotive-grade construction. It has passed stress tests including temperature cycling, humidity bias, and mechanical shock, making it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is mandatory.
What is the maximum clamping voltage of P6SMB22CAHE3_B/H and why does it matter?
The P6SMB22CAHE3_B/H has a maximum clamping voltage (VC) of 30.6 V at 19.6 A peak pulse current. This value matters because it defines the highest voltage imposed on the protected circuit during a surge event; for a 24 V nominal system, this 27 % overvoltage margin ensures downstream ICs remain within their absolute maximum ratings and avoid latch-up or permanent damage during IEC 61000-4-5 compliant transients.
How does the SMB (DO-214AA) package of P6SMB22CAHE3_B/H compare to larger packages like SMC?
The SMB (DO-214AA) package of P6SMB22CAHE3_B/H measures 4.57 mm × 3.94 mm, offering 40 % smaller footprint than SMC (DO-214AB). While SMC variants (e.g., SMCJ22CA) deliver higher peak power (1500 W), the P6SMB22CAHE3_B/H achieves 600 W in compact form-ideal for dense PCB layouts in automotive ECUs and portable telecom equipment where board space is constrained but 600 W surge immunity suffices.
What soldering standards does P6SMB22CAHE3_B/H comply with?
P6SMB22CAHE3_B/H features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 for solderability, and meets MSL Level 1 per J-STD-020 with a maximum reflow peak temperature of 260 °C. This allows direct integration into standard lead-free SMT processes without pre-baking or special handling, reducing manufacturing complexity and cost in high-volume automotive and industrial assembly lines.
