Product details
Overview
P6SMB62CAHM3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 53.0 V standoff voltage (VWM), and 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current. It protects signal lines and power rails in automotive sensor interfaces, industrial I/O modules, and telecom front-end circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB62CAHM3_B/I datasheet, P6SMB62CAHM3_B/I pinout, P6SMB62CAHM3_B/I application, or P6SMB62CAHM3_B/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its breakdown threshold (58.9–65.1 V), it rapidly switches to low-impedance conduction, diverting surge current away from downstream circuitry while maintaining clamped voltage ≤85.0 V. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive surges.
Designed for bidirectional protection, P6SMB62CAHM3_B/I exhibits symmetrical electrical characteristics in both polarities-no cathode/anode marking-and supports operation across -65 °C to +150 °C junction temperature range. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling effective heat dissipation without external heatsinking under typical PCB layout conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, 64 V VWM, 100 W peak power (vs. 600 W), higher clamping ratio (VC/VWM = 1.33 vs. 1.60) | Limited to lower-energy transients (IEC 61000-4-2 only); unsuitable for load-dump or high-repetition surges | Select when cost-sensitive designs require basic ESD protection without automotive or industrial surge compliance |
| SMCJ64CA | Same VWM (64 V), 1500 W peak power, larger SMC (DO-214AB) package (7.11 mm × 6.22 mm) | Higher surge handling but requires larger PCB area and different stencil design; not drop-in compatible | Choose when system-level surge testing exceeds 600 W requirements (e.g., MIL-STD-1275, ISO 16750-2) |

FAQ
What does the "CA" suffix indicate in P6SMB62CAHM3_B/I?
The "CA" suffix in P6SMB62CAHM3_B/I denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities without cathode/anode orientation requirements. This differs from unidirectional "A" versions, which require correct polarity placement and exhibit forward conduction behavior. Bidirectional operation simplifies layout for AC-coupled or differential signal lines and eliminates risk of incorrect mounting.
Is P6SMB62CAHM3_B/I suitable for automotive applications?
Yes, P6SMB62CAHM3_B/I is AEC-Q101 qualified, as confirmed by the "HM3_B" suffix indicating halogen-free, RoHS-compliant construction with automotive-grade reliability validation. It meets requirements for temperature cycling, mechanical shock, and humidity testing per AEC-Q101, making it appropriate for engine control units, ADAS camera modules, and body electronics where sustained operation from -40 °C to +125 °C ambient is required.
What is the maximum clamping voltage of P6SMB62CAHM3_B/I and why does it matter?
The maximum clamping voltage (VC) of P6SMB62CAHM3_B/I is 85.0 V at 7.1 A peak pulse current (10/1000 μs waveform). This value defines the highest voltage imposed on protected circuitry during a surge event. For example, if an MCU I/O pin has an absolute maximum rating of 80 V, this clamping voltage exceeds that limit-so P6SMB62CAHM3_B/I must be paired with upstream series impedance or used only where downstream components tolerate ≥85 V transient stress.
How does the SMB (DO-214AA) package of P6SMB62CAHM3_B/I compare to SMC or SMA packages?
The SMB package of P6SMB62CAHM3_B/I measures 4.57 mm × 3.94 mm × 2.20 mm-smaller than SMC (DO-214AB, 7.11 mm × 6.22 mm) and larger than SMA (DO-214AC, 4.32 mm × 2.62 mm). Its 600 W rating strikes a balance between power handling and board space; SMC offers higher surge capacity (1500 W) but consumes >2× PCB area, while SMA is limited to 400 W. P6SMB62CAHM3_B/I's SMB footprint supports automated placement without sacrificing critical energy absorption.
What is the significance of the "_B/I" suffix in P6SMB62CAHM3_B/I?
The "_B/I" suffix in P6SMB62CAHM3_B/I specifies two attributes: "B" indicates AEC-Q101 qualification for the 6.8 V to 220 V voltage range, and "I" denotes packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format ensures traceability for automotive production lots and supports high-volume SMT assembly with consistent feeding performance and moisture barrier compliance (MSL Level 1).
