Product details
Overview
P6SMB130CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 3.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor units, industrial I/O modules, and telecom interface circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB130CAHM3_A/H datasheet, P6SMB130CAHM3_A/H pinout, P6SMB130CAHM3_A/H application, or P6SMB130CAHM3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, 179 V VC under 3.4 A surge, thermal resistance (RθJA = 100 °C/W), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its 130 V stand-off threshold, it avalanches symmetrically in both directions to clamp the line at ≤179 V while diverting up to 3.4 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown and low leakage (<1 μA at VWM).
Designed for automated SMT assembly, it meets MSL Level 1 (260 °C peak reflow) and JESD201 Class 2 whisker resistance. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification - critical for automotive-grade reliability in engine control, ADAS sensor interfaces, and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 130 V - maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown |
| VBR (Breakdown) | 124–137 V at 1 mA - tight 5% tolerance ensures predictable turn-on across temperature and unit variation |
| VC (Clamping) | 179 V at IPPM = 3.4 A - limits transient voltage seen by downstream ICs to safe levels during surge events |
| PPPM | 600 W - peak power handling capability with 10/1000 μs waveform enables robust protection against lightning-induced surges |
| ID (Leakage) | <1 μA at 130 V - negligible standby current preserves signal integrity and battery life in always-on circuits |
| TJ max | +150 °C - extended junction temperature rating supports operation in under-hood automotive environments |
| RθJA | 100 °C/W - thermal resistance informs PCB copper pad sizing (0.2" × 0.2") for sustained 5.0 W power dissipation |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; symmetrical cathode/anode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink (bidirectional) | Accepts surge current during positive or negative overvoltage excursions; connects to protected line |
| Cathode | Transient current sink (bidirectional) | Completes low-impedance path to ground or reference rail during clamping; electrically identical to anode |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA | Same VWM (130 V), lower PPPM (400 W), higher VC (193 V at 3.1 A), SMA package (larger RθJA) | Limited to lower-energy transients; less suitable for automotive load dump where 600 W margin is required | Select when cost sensitivity outweighs peak power headroom and board space permits larger SMA footprint |
| SMCJ130CA | Same VWM (130 V), higher PPPM (1500 W), same VC (179 V), SMC package (lower RθJA = 25 °C/W) | Better thermal performance and surge margin but requires 3× PCB area; overqualified for compact consumer designs | Choose for industrial motor drives or EV charging stations needing >1000 W surge capacity and enhanced thermal derating |
Compared with P6SMB130CAHM3_A/H, SMAJ130CA trades peak power and thermal efficiency for smaller size and lower cost, while SMCJ130CA delivers superior surge handling and cooling at the expense of footprint - making P6SMB130CAHM3_A/H the optimal balance of AEC-Q101 reliability, 600 W capability, and SMB space efficiency.

FAQ
What does the "HM3" suffix indicate in P6SMB130CAHM3_A/H?
The HM3 suffix in P6SMB130CAHM3_A/H denotes halogen-free, RoHS-compliant construction and AEC-Q101 qualification. This means the device meets automotive reliability standards for temperature cycling, humidity resistance, and mechanical shock, while also complying with environmental directives restricting brominated flame retardants and other halogens - essential for Tier 1 automotive suppliers and green manufacturing programs.
Is P6SMB130CAHM3_A/H unidirectional or bidirectional?
P6SMB130CAHM3_A/H is a bidirectional TVS diode, indicated by the "CA" suffix. It provides symmetrical clamping in both polarities - ideal for protecting AC-coupled signal lines, differential buses like CAN or RS-485, and any circuit where voltage transients may swing positive or negative relative to ground. Unlike unidirectional variants (e.g., P6SMB130A), it has no cathode band marking.
What is the clamping voltage of P6SMB130CAHM3_A/H and why does it matter?
The clamping voltage (VC) of P6SMB130CAHM3_A/H is 179 V at 3.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value defines the maximum voltage imposed on the protected circuit during a surge event. A lower VC relative to VWM (130 V) - here a ratio of 1.38 - ensures downstream ICs experience minimal overvoltage stress, directly improving system robustness against ISO 7637-2 and IEC 61000-4-5 threats.
Can P6SMB130CAHM3_A/H replace P6SMB130A in a design?
No - P6SMB130CAHM3_A/H cannot directly replace unidirectional P6SMB130A without circuit review. While both share identical VWM (130 V) and VC (179 V), P6SMB130A is unidirectional (cathode-marked) and intended for DC-biased lines like power rails. Substituting the bidirectional P6SMB130CAHM3_A/H on a DC path introduces unintended conduction during reverse bias, risking latch-up or damage. Always verify polarity requirements before interchange.
What PCB layout guidance applies to P6SMB130CAHM3_A/H?
For optimal thermal and electrical performance, mount P6SMB130CAHM3_A/H using the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, per Vishay's datasheet Figure 2. Minimize trace length between the device and protected node, avoid vias in high-current paths, and ensure ground plane continuity beneath the SMB footprint to reduce inductance and improve clamping response. Thermal relief patterns are not recommended for surge paths.
