Product details
Overview
P6SMB36CA-M3/5B 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 a 30.8 V standoff voltage (VWM), 34.2–37.8 V breakdown voltage (VBR) at 1 mA test current, 49.9 V maximum clamping voltage (VC) at 12.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive control units.
For engineers reviewing the P6SMB36CA-M3/5B datasheet, P6SMB36CA-M3/5B pinout, P6SMB36CA-M3/5B application, or P6SMB36CA-M3/5B equivalent, this device delivers verified bidirectional surge suppression with halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification eligibility via HM3 suffix variants - critical for high-reliability board-level ESD and lightning transient protection design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while the low incremental surge resistance enables rapid clamping response during fast transients such as IEC 61000-4-5 surge events.
The device 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 (on recommended 0.2" × 0.2" copper pads) and 20 °C/W junction-to-lead, supporting reliable operation under repetitive surge conditions up to 0.01% duty cycle.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36CA | Same VWM/VC specs but lower 400 W PPPM; SMA package (smaller footprint, higher thermal resistance) | Limited to lower-energy transients; less suitable for IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is ≤ Level 2 |
| 1.5SMC36CA | Same electrical ratings but larger SMC (DO-214AB) package; 1000 W PPPM rating | Higher surge margin and better thermal dissipation; requires larger PCB area | Choose for mission-critical industrial controls where extended surge endurance is prioritized over size |
Compared with SMAJ36CA and 1.5SMC36CA, P6SMB36CA-M3/5B offers optimal balance of 600 W surge capacity, SMB footprint compatibility, and halogen-free compliance - making it ideal for cost-sensitive, high-volume automotive and industrial designs requiring validated AEC-Q101 readiness.

FAQ
What is the clamping voltage of P6SMB36CA-M3/5B at its rated peak pulse current?
The P6SMB36CA-M3/5B has a maximum clamping voltage (VC) of 49.9 V at 12.0 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuits during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings. The P6SMB36CA-M3/5B maintains this clamping performance across its specified operating temperature range.
Is P6SMB36CA-M3/5B suitable for automotive applications requiring AEC-Q101 qualification?
The base P6SMB36CA-M3/5B is halogen-free and RoHS-compliant but not AEC-Q101 qualified. However, Vishay offers the HM3 variant (e.g., P6SMB36CAHM3_B/I) with full AEC-Q101 qualification for automotive use. Engineers specifying P6SMB36CA-M3/5B for automotive designs should verify whether the HM3 suffix version is required for qualification compliance - the P6SMB36CA-M3/5B itself meets all electrical and mechanical specs needed for such applications except formal stress-test certification.
How does the bidirectional configuration of P6SMB36CA-M3/5B affect PCB layout?
The P6SMB36CA-M3/5B has no polarity marking and functions identically in both directions, eliminating orientation constraints during PCB placement. This simplifies layout for AC-coupled lines, differential buses (e.g., RS-485), or floating sensors where voltage polarity may reverse. Unlike unidirectional TVS diodes, the P6SMB36CA-M3/5B requires no cathode band alignment - reducing assembly errors and enabling automated optical inspection (AOI) tolerance. Its SMB footprint remains unchanged from unidirectional variants.
What is the thermal resistance of P6SMB36CA-M3/5B, and how does it impact surge handling?
The P6SMB36CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per JEDEC standards. This value directly affects its ability to sustain repetitive surges: higher ambient temperatures reduce allowable pulse repetition rate. For example, at 75 °C ambient, the device must be derated to ~65% of its 600 W rating per Figure 2. Proper pad sizing and thermal vias are essential to maintain P6SMB36CA-M3/5B performance under sustained stress.
Does P6SMB36CA-M3/5B meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, the P6SMB36CA-M3/5B meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This means it can be processed using standard lead-free soldering profiles without baking or dry-pack requirements - significantly simplifying manufacturing logistics. The matte tin-plated leads also comply with J-STD-002 and JESD22-B102 for solderability, and the device passes JESD201 Class 2 whisker testing, ensuring long-term reliability in P6SMB36CA-M3/5B-based assemblies.
