Product details
Overview
P6SMB180AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 180 V standoff voltage (VWM), 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB180AHM3/I datasheet, P6SMB180AHM3/I pinout, P6SMB180AHM3/I application, or P6SMB180AHM3/I equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, thermal resistance (RθJA = 100 °C/W), AEC-Q101 qualification status, unidirectional polarity marking, and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1 μA leakage at 154 V), but triggers avalanche breakdown when transient voltage exceeds its 171–189 V breakdown range (VBR at 1 mA), diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable, repeatable clamping performance across temperature.
The device is optimized for automated SMT placement on PCBs with 0.2" × 0.2" copper pads per terminal, supports 100 A non-repetitive forward surge (IFSM), and maintains operation from −65 °C to +150 °C junction temperature. Its MSL Level 1 rating confirms compatibility with standard reflow profiles up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse operating voltage before significant leakage; defines upper limit of normal system voltage tolerance. |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - Confirmed avalanche initiation range; ensures reliable triggering above system max operating voltage. |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; must stay below downstream device's absolute max rating. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capacity per single 10/1000 μs event; determines survivability against common IEC 61000-4-5 threats. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits. |
| TJ max | +150 °C - Enables use in under-hood automotive or high-ambient industrial environments without derating. |
| Package | SMB (DO-214AA) - Standardized 2-pin surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with JEDEC MS-012AC. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional configuration with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-voltage rail; forms return path for clamped surge current. |
| Cathode | High-side protection node | Connected to protected line (e.g., power rail or signal trace); polarity band identifies this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Supports robust immunity to IEC 61000-4-5 Level 3/4 surges without external heat sinking. |

| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declarations for green manufacturing. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without pre-baking or special handling. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD or inductive kick), improving protection fidelity. |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V supply rails in engine control units (ECUs) and body control modules (BCMs) from load dump and alternator ripple.

Use Scenario: Snubbing inductive kickback from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Flyback diode replacement for faster, more predictable clamping than standard rectifiers. Use Value: Tight VBR tolerance (±5.5%) and low VC ensure consistent motor driver FET gate-source voltage stays within safe limits during commutation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ180A-E3/5B | Same VWM (154 V), VC = 246 V, but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 150 °C/W). | Limited to lower-energy surges; unsuitable for automotive load dump where 600 W is required. | Select only if board space is constrained and surge threat level is ≤ IEC 61000-4-5 Level 2. |
| 1.5SMC180AHE3_A/H | Same electrical specs (VWM, VBR, VC), but SMC package (larger, 7.11 mm × 6.22 mm); AEC-Q101 qualified, halogen-free. | Higher thermal mass enables better sustained surge handling; requires larger PCB area and different stencil design. | Choose when thermal performance under repetitive surges is critical and layout allows SMC footprint. |
Compared with SMAJ180A-E3/5B and 1.5SMC180AHE3_A/H, P6SMB180AHM3/I delivers optimal balance of 600 W surge capability, SMB footprint compactness, AEC-Q101 qualification, and halogen-free compliance-making it preferred for space-constrained automotive and industrial designs requiring full IEC 61000-4-5 Level 4 immunity.

FAQ
What is the clamping voltage of P6SMB180AHM3/I at its rated peak pulse current?
The P6SMB180AHM3/I has a maximum clamping voltage (VC) of 246 V when subjected to its specified peak pulse current (IPPM) of 2.4 A using the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet (Document Number: 88370) and defines the upper voltage limit imposed on protected circuitry during surge events. Maintaining VC below the absolute maximum rating of downstream components is essential for reliable protection.
Is P6SMB180AHM3/I qualified for automotive applications?
Yes, P6SMB180AHM3/I is AEC-Q101 qualified, as confirmed by the "HM3" suffix and documentation in the Vishay P6SMB datasheet (Revision: 09-Jan-2024). The HM3 designation indicates halogen-free, RoHS-compliant construction with full AEC-Q101 stress testing-including temperature cycling, humidity bias, and mechanical shock-making P6SMB180AHM3/I suitable for under-hood and chassis-mounted automotive electronics.
What does the "I" suffix in P6SMB180AHM3/I indicate?
The "I" suffix in P6SMB180AHM3/I specifies the packaging format: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This is defined in the Ordering Information table (page 3 of Document Number: 88370) and distinguishes it from the "H" suffix (7-inch reel, 750 units). The "I" format supports high-volume SMT production with extended reel life and reduced changeover frequency.
How does the thermal resistance of P6SMB180AHM3/I affect its surge handling capability?
P6SMB180AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This value directly impacts its ability to dissipate energy during repetitive surges: higher RθJA limits duty cycle and repetition rate before junction temperature exceeds 150 °C. For single-event protection (e.g., lightning), thermal resistance is less critical than peak power rating-but for burst-mode transients, board layout and copper area become decisive factors for P6SMB180AHM3/I reliability.
Can P6SMB180AHM3/I be used in bidirectional configurations?
No, P6SMB180AHM3/I is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA") and absence of bidirectional VBR/VWM specifications in its row of the Electrical Characteristics table. Its cathode band marking confirms polarity-sensitive installation. For bidirectional protection at 180 V, a part like P6SMB180CAHM3/I would be required-but that variant is not offered in the P6SMB family per the datasheet; the highest bidirectional VWM listed is 185 V (P6SMB185CA), making P6SMB180AHM3/I strictly unidirectional.
