Product details
Overview
P6SMB200CAHM3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM). It delivers 600 W peak pulse power with 10/1000 µs waveform and is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB200CAHM3_B/H datasheet, P6SMB200CAHM3_B/H pinout, P6SMB200CAHM3_B/H application, or P6SMB200CAHM3_B/H equivalent, this device serves as a robust, low-profile overvoltage clamp for bidirectional signal lines and power rails in harsh environments-especially where automotive-grade reliability, fast response (<1 ns), and repeatable surge immunity are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VWM, VBR, and VC specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage performance (≤1.0 µA at VWM) and low incremental surge resistance, enabling precise clamping under repetitive transients.
The device uses a planar silicon avalanche structure optimized for low capacitance (typ. <50 pF at 0 V, per family data), fast response time (<1.0 ns), and thermal stability up to TJ = 150 °C. It meets J-STD-020 MSL Level 1 and supports reflow soldering at peak 260 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Same VWM (200 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for automotive under-hood use. | Select when space-constrained PCBs require smaller footprint and surge requirements are ≤400 W. |
| 1.5KE200CA | Higher PPPM (1500 W), through-hole DO-201 package; VC = 324 V (higher overshoot); no AEC-Q101 or halogen-free certification. | Designed for industrial mains-level protection; incompatible with SMT assembly and automotive qualification needs. | Choose only for legacy through-hole designs needing >600 W rating and where reflow compatibility is irrelevant. |

FAQ
What is the clamping voltage of P6SMB200CAHM3_B/H at its rated peak pulse current?
The P6SMB200CAHM3_B/H has a maximum clamping voltage (VC) of 274 V at its specified peak pulse current (IPPM) of 2.2 A under a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB200CAHM3_B/H maintains this clamping performance consistently across its qualified operating temperature range.
Is P6SMB200CAHM3_B/H suitable for automotive applications?
Yes, P6SMB200CAHM3_B/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (HM3 suffix), making it approved for automotive use in engine control, body electronics, and ADAS subsystems. Its 150 °C maximum junction temperature, MSL Level 1 moisture sensitivity, and 260 °C reflow compatibility align with automotive manufacturing and field reliability requirements. The P6SMB200CAHM3_B/H is explicitly designated for automotive-grade deployment per Vishay's ordering nomenclature (_B/H suffix).
How does the bidirectional design of P6SMB200CAHM3_B/H affect its circuit implementation?
The bidirectional design of P6SMB200CAHM3_B/H eliminates polarity concerns during placement-no cathode band marking is present, and either terminal functions as anode or cathode depending on transient polarity. This simplifies layout for AC-coupled lines (e.g., CAN bus, RS-485), reduces BOM count versus dual unidirectional devices, and ensures symmetrical clamping behavior. The P6SMB200CAHM3_B/H achieves identical VWM, VBR, and VC in both directions, verified per datasheet electrical characteristics table.
What is the thermal resistance of P6SMB200CAHM3_B/H, and how does it impact power dissipation?
P6SMB200CAHM3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended pad layout (0.2" × 0.2" copper pads per terminal). At ambient temperatures above 25 °C, its 5.0 W steady-state power dissipation (PD) must be derated linearly per Figure 2 in the datasheet. This RθJA value directly governs safe continuous operation and influences layout decisions-such as copper area and thermal vias-to maintain TJ ≤ 150 °C. The P6SMB200CAHM3_B/H thermal performance is validated per JESD51 standards.
Can P6SMB200CAHM3_B/H replace older P6SMB200CA variants in existing designs?
Yes, P6SMB200CAHM3_B/H is a direct replacement for prior P6SMB200CA versions with E3 or M3 suffixes, retaining identical electrical specs, SMB package dimensions, and pinout. The HM3 suffix adds halogen-free construction and AEC-Q101 qualification without altering form, fit, or function. No PCB changes are required-footprint, solder profile, and clamping behavior remain unchanged. The P6SMB200CAHM3_B/H is fully backward-compatible while enhancing environmental and automotive compliance.
