Product details
Overview
P6SMB180AHE3_B/H 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 clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs). It protects MOSFETs, ICs, and sensor signal lines in automotive powertrain control units against inductive switching transients.
For engineers reviewing the P6SMB180AHE3_B/H datasheet, P6SMB180AHE3_B/H pinout, P6SMB180AHE3_B/H application, or P6SMB180AHE3_B/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with a cathode-band-marked polarity. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients induced by relay or solenoid switching.
The device is rated for repetitive 10/1000 μs pulses at 0.01 % duty cycle and derates linearly above 25 °C ambient per Figure 2. It meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C) and supports automotive-grade reliability via AEC-Q101 qualification (HE3_B suffix).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - Voltage at which device enters avalanche conduction; ensures predictable turn-on threshold. |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - Peak voltage seen by protected circuit during 10/1000 μs transient; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy absorption capability under standardized 10/1000 μs waveform. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | 150 °C - Maximum junction temperature; sets thermal design limits for PCB copper pad sizing and airflow requirements. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; used to calculate temperature rise under DC bias. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, matte tin-plated leads, RoHS-compliant and AEC-Q101 qualified (HE3_B suffix). Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage return path; forms clamping loop with cathode during transient events. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 12 V battery rail); avalanche conduction occurs from cathode to anode when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TCT, and ESD. |
| Glass passivated junction | Enables stable breakdown characteristics over temperature and lifetime, minimizing parameter drift in harsh environments. |
| 600 W peak pulse rating | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-earth) when combined with appropriate series impedance. |
| MSL Level 1 moisture sensitivity | Allows direct placement without baking; compatible with standard lead-free reflow profiles up to 260 °C peak. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients, reducing risk of gate oxide damage in protected MOSFETs. |
Applications
| Automotive Powertrain Control | Industrial Motor Drive Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient 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 = 140 °C/W). | Limited to lower-energy transients; unsuitable for automotive load-dump scenarios requiring 600 W rating. | Select only if board space is constrained and surge energy is verified ≤400 W. |
| 1.5SMC180A | Same electrical specs (VWM = 154 V, VC = 246 V, PPPM = 600 W), but SMC (DO-214AB) package (larger, 7.11 mm × 6.22 mm). | Higher thermal mass improves DC power handling but requires larger PCB area and may not fit dense automotive layouts. | Choose when enhanced thermal robustness under sustained surge repetition is required. |
Compared with P6SMB180AHE3_B/H, SMAJ180A-E3/5B trades peak power and thermal performance for compactness, while 1.5SMC180A retains full 600 W capability at the cost of footprint size-making P6SMB180AHE3_B/H the optimal balance of AEC-Q101 reliability, SMB form factor, and automotive-grade surge margin.

FAQ
What is the clamping voltage of P6SMB180AHE3_B/H under a 10/1000 μs surge?
The P6SMB180AHE3_B/H clamps to a maximum of 246 V when subjected to its rated peak pulse current of 2.4 A under the standardized 10/1000 μs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88370, and defines the upper voltage limit imposed on protected circuitry during transient events.
Is P6SMB180AHE3_B/H qualified for automotive use?
Yes, P6SMB180AHE3_B/H is AEC-Q101 qualified, as confirmed by the "HE3_B" suffix in its ordering code and explicitly stated in the Ordering Information table (page 3) and Features section of Vishay document 88370. This qualification covers temperature cycling, highly accelerated life testing, and ESD robustness required for automotive powertrain and chassis applications.
What does the "_B/H" suffix indicate in P6SMB180AHE3_B/H?
The "_B" denotes AEC-Q101 qualification level for the P6SMB180AHE3_B/H device, while "/H" specifies the packaging format: 7-inch diameter plastic tape and reel with 750 units per reel. This suffix structure is defined in the Ordering Information section (page 3) of Vishay document 88370 and aligns with Vishay's standard automotive-grade part numbering convention.
How does P6SMB180AHE3_B/H differ from bidirectional variants like P6SMB180CA?
P6SMB180AHE3_B/H is unidirectional, with a cathode band marking and forward conduction capability (VF = 3.5 V at 50 A), whereas P6SMB180CA is bidirectional and lacks polarity marking. The unidirectional version provides lower leakage and better DC blocking in single-rail protection schemes, while the bidirectional variant suits AC-coupled or dual-polarity signal lines.
What is the thermal resistance of P6SMB180AHE3_B/H, and how is it measured?
The P6SMB180AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured with the device mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Thermal Characteristics table (page 3) of Vishay document 88370. This value is critical for calculating junction temperature rise under DC bias or repetitive surge conditions.
