Product details
Overview
P6SMB13CAHM3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features 13 V standoff voltage (VWM), 14.5 V maximum clamping voltage (VC) at 33.0 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6SMB13CAHM3_B/H datasheet, P6SMB13CAHM3_B/H pinout, P6SMB13CAHM3_B/H application, or P6SMB13CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.115), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable avalanche characteristics and fast response time (<1 ns), while the low incremental surge resistance supports effective energy diversion during transient events.
The P6SMB13CAHM3_B/H is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; thermal resistance is 100 °C/W junction-to-ambient (RθJA) and 20 °C/W junction-to-lead (RθJL), enabling reliable operation under repetitive 0.01% duty cycle surges when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 11.1 V - maximum reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 12.4 V min / 13.7 V max at 1.0 mA - ensures consistent avalanche initiation across production lots |
| VC (Clamping Voltage) | 18.2 V at 33.0 A IPPM - limits downstream voltage stress during 10/1000 μs transients |
| PPPM (Peak Pulse Power) | 600 W - sustains single high-energy surges without failure under standardized waveform |
| ID (Reverse Leakage) | 5.0 μA max at VWM - negligible standby current impact on low-power sensor or signal lines |
| TJ max | 150 °C - supports operation in under-hood automotive and industrial environments |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 0.220" × 0.130" footprint and J-STD-020 MSL Level 1 rating |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | One terminal of symmetrical PN junction; conducts during negative-going transients |
| Cathode | Transient current entry (positive polarity) | Other terminal of symmetrical PN junction; conducts during positive-going transients |

Use Scenario: Suppressing commutation spikes from brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines). IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals or H-bridge outputs to divert inductive kickback energy. Use Value: Withstands repetitive 0.01% duty cycle surges, extending MOSFET lifetime and eliminating need for snubber RC networks in cost-sensitive designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA-E3/5B | Same VWM (11.1 V), VC = 21.5 V at 27.7 A; lower PPPM (400 W); SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; less suitable for IEC 61000-4-5 level 3+ testing | Select when board space is constrained and surge energy is ≤400 W; verify thermal performance with smaller pad area |
| 1.5SMC13CA | Same electrical specs but in larger SMC (DO-214AB) package; RθJA = 60 °C/W; higher IPPM (37.1 A) | Better thermal handling for high-repetition-rate surges; requires larger PCB real estate | Choose for industrial power supplies needing enhanced thermal margin and higher surge repetition tolerance |
Compared with SMAJ13CA-E3/5B and 1.5SMC13CA, the P6SMB13CAHM3_B/H delivers optimal balance of 600 W surge capacity, AEC-Q101 qualification, and SMB footprint-making it preferred for space-constrained automotive and industrial modules requiring validated reliability and standardized assembly.

FAQ
What is the clamping voltage of P6SMB13CAHM3_B/H at its rated peak pulse current?
The P6SMB13CAHM3_B/H has a maximum clamping voltage (VC) of 18.2 V at 33.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test method and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB13CAHM3_B/H maintains this clamping performance across its qualified operating temperature range and is verified per Vishay's production testing protocol.
Is P6SMB13CAHM3_B/H suitable for automotive applications?
Yes, P6SMB13CAHM3_B/H is AEC-Q101 qualified and manufactured with HM3 suffix indicating halogen-free, RoHS-compliant construction and automotive-grade reliability validation. It is explicitly rated for use in engine control, body electronics, and ADAS sensor interfaces where transient immunity and long-term stability under thermal cycling are required. The P6SMB13CAHM3_B/H meets all stress tests defined in AEC-Q101 Rev D, including HTGB, AC-H3TRB, and mechanical shock.
What does the "_B/H" suffix mean in P6SMB13CAHM3_B/H?
The "_B" denotes AEC-Q101 qualification for the P6SMB13CAHM3_B/H series, while "/H" specifies packaging in 7" diameter plastic tape and reel with 750 units per reel. This ordering code aligns with Vishay's standardized nomenclature where HM3 indicates halogen-free RoHS compliance, CA confirms bidirectional configuration, and B/H jointly identifies automotive qualification plus reel format. The P6SMB13CAHM3_B/H is not interchangeable with non-B variants in automotive production without requalification.
How does P6SMB13CAHM3_B/H compare to unidirectional versions like P6SMB13AHM3_B/H?
The P6SMB13CAHM3_B/H is bidirectional with symmetrical clamping in both polarities, whereas P6SMB13AHM3_B/H is unidirectional and conducts only in reverse bias. This makes the P6SMB13CAHM3_B/H appropriate for AC-coupled or differential signal lines (e.g., RS-485, CAN), while the unidirectional version suits DC power rail protection. Both share identical VWM (11.1 V), VC (18.2 V), and PPPM (600 W), but the P6SMB13CAHM3_B/H has no cathode band marking and higher ID (5.0 μA vs. 1.0 μA at VWM).
What is the thermal resistance of P6SMB13CAHM3_B/H and how does it affect layout?
The P6SMB13CAHM3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per Vishay's recommended layout. To maintain safe junction temperatures during repetitive surges, PCB layout must replicate this pad size and avoid excessive trace length or isolation. Derating curves in Figure 2 apply directly to the P6SMB13CAHM3_B/H and require adherence to these thermal guidelines for sustained reliability.
