Product details
Overview
SMBJ36CD-M3/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 or power lines. It features a 36 V stand-off voltage (VWM), 40.6–43.6 V breakdown voltage (VBR) at 1 mA, 57.3 V maximum clamping voltage (VC) at 10.5 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ36CD-M3/H datasheet, SMBJ36CD-M3/H pinout, SMBJ36CD-M3/H application, or SMBJ36CD-M3/H equivalent, this page delivers verified electrical parameters, bidirectional polarity behavior, thermal derating curves, MSL Level 1 reflow compatibility, and RoHS-compliant halogen-free construction - all critical for ESD/surge protection design-in and BOM validation.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR min/max (40.6–43.6 V), VWM (36 V), and VC (57.3 V at IPPM = 10.5 A) in forward and reverse directions. Its low incremental surge resistance and fast response time enable effective suppression of lightning-induced surges and inductive switching transients.
Thermal performance is defined by RθJA = 125 °C/W (on minimum pad layout) and RθJM = 20 °C/W, supporting operation up to TJ = 150 °C. Power dissipation is rated at 1.0 W at TA = 25 °C and derates linearly above that temperature per Fig. 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse stand-off voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (min/max) | 40.6 V / 43.6 V at IT = 1 mA - Tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 57.3 V at 10.5 A - Clamped voltage during 10/1000 μs surge; limits stress on downstream components |
| PPPM | 600 W - Peak pulse power handling capability under standardized transient waveform (duty cycle ≤ 0.01 %) |
| ID @ VWM | ≤ 0.5 μA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss |
| TJ max | 150 °C - Maximum junction temperature; enables reliable operation in industrial ambient environments |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA-E3/52 (Vishay) | Same VWM/VBR/VC specs; differs in packaging (tape-and-reel vs. bulk) and MSL rating (Level 1 vs. unspecified in older revision) | Identical electrical performance; suited for legacy procurement where M3/H suffix not mandated | Select SMBJ36CA-E3/52 only if halogen-free and JESD201 Class 2 whisker compliance are not required. |
| 1.5SMC36CA (ON Semiconductor) | Same 36 V VWM, but higher VC = 58.1 V at 10.3 A; larger SMC (DO-214AB) package (7.11 mm × 6.22 mm) | Requires PCB layout change due to larger footprint; suitable where higher surge margin justifies added board area | Choose 1.5SMC36CA only when 600 W rating must be sustained at elevated ambient temperatures where SMB thermal resistance becomes limiting. |
Compared with SMBJ36CD-M3/H, SMBJ36CA-E3/52 offers identical protection performance but lacks documented halogen-free and whisker-test compliance, while 1.5SMC36CA trades compact SMB size for higher thermal mass and slightly relaxed clamping - making SMBJ36CD-M3/H optimal for space-constrained, environmentally regulated industrial designs.

FAQ
What is the clamping voltage of SMBJ36CD-M3/H at its rated peak pulse current?
The SMBJ36CD-M3/H exhibits a maximum clamping voltage (VC) of 57.3 V when subjected to its rated peak pulse current (IPPM) of 10.5 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry sees no more than 57.3 V during surge events - a critical parameter for ensuring compatibility with 3.3 V or 5 V logic interfaces. The SMBJ36CD-M3/H maintains this clamping performance across its full operating temperature range.
Is SMBJ36CD-M3/H suitable for bidirectional signal line protection?
Yes, SMBJ36CD-M3/H is explicitly designed for bidirectional protection: the "CD" suffix denotes bidirectional functionality, and its electrical characteristics - including VBR, VC, and IPPM - apply identically in both polarities. Unlike unidirectional variants, it has no cathode band and can be installed without orientation concern. This makes SMBJ36CD-M3/H ideal for protecting differential buses (e.g., RS-485, CAN) or AC-coupled signal paths where voltage transients may swing positive or negative relative to ground.
Does SMBJ36CD-M3/H meet lead-free and RoHS requirements?
Yes, SMBJ36CD-M3/H carries the "M3" suffix, which certifies halogen-free construction, RoHS compliance, and industrial-grade qualification. It satisfies JEDEC JESD201 Class 2 whisker testing and is rated MSL Level 1 per J-STD-020 - allowing direct placement into Pb-free reflow profiles peaking at 260 °C without preconditioning. These attributes are fully documented in Vishay's 87606 datasheet revision 09-Jan-2024 and confirmed on Vishay's official product page.
How does the thermal resistance of SMBJ36CD-M3/H affect its power handling?
SMBJ36CD-M3/H has a typical junction-to-ambient thermal resistance (RθJA) of 125 °C/W when mounted on the minimum recommended pad layout. This means a 1.0 W steady-state power dissipation raises the junction temperature by 125 °C above ambient - limiting continuous use. However, its 600 W peak pulse rating applies only to short-duration transients (≤50 ms), where thermal mass dominates. For repeated surges, designers must apply derating per Fig. 2 in the datasheet to avoid exceeding TJ(max) = 150 °C.
Can SMBJ36CD-M3/H replace unidirectional SMBJ36D-M3/H in existing designs?
No - SMBJ36CD-M3/H is not a drop-in replacement for SMBJ36D-M3/H. While both share identical VWM (36 V), VBR, and VC ratings, the unidirectional SMBJ36D-M3/H requires correct cathode orientation and only clamps in reverse bias, whereas SMBJ36CD-M3/H clamps symmetrically in both directions and has no polarity marking. Swapping them without reviewing circuit topology risks ineffective protection on forward-polarity transients or unintended conduction paths. Always validate layout and signal polarity before substitution.
