Product details
Overview
SMBJ36D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive switching transients and ESD events on power and signal 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, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBJ36D-M3/H datasheet, SMBJ36D-M3/H pinout, SMBJ36D-M3/H application, or SMBJ36D-M3/H equivalent, key selection criteria include unidirectional polarity, tight ±3.5 % VBR tolerance, low 0.5 μA reverse leakage at VWM, M3 halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on industrial-grade PCBs.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream ICs or MOSFETs, activating when transient voltage exceeds its VBR threshold to shunt surge current away from protected circuitry. Its low incremental surge resistance and fast response time ensure effective suppression of lightning-induced surges and inductive kickback.
The SMBJ36D-M3/H is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 with 260 °C reflow peak, supporting robust thermal performance under repetitive surge conditions. Its 125 °C/W junction-to-ambient thermal resistance assumes minimum recommended pad layout per Vishay specification.

FAQ
What is the maximum clamping voltage of the SMBJ36D-M3/H under a 10/1000 μs surge?
The SMBJ36D-M3/H has a maximum clamping voltage (VC) of 57.3 V at 10.5 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ36D-M3/H maintains this clamping performance consistently across its specified operating temperature range.
Is the SMBJ36D-M3/H suitable for bidirectional transient protection?
No, the SMBJ36D-M3/H is a unidirectional TVS diode, indicated by the "D" suffix (not "CD"). It conducts only in reverse bias above VBR and must be oriented with the cathode band toward the protected line. For bidirectional protection, use SMBJ36CD-M3/H, which provides symmetrical clamping in both polarities. The SMBJ36D-M3/H is not rated for reverse conduction and will not suppress positive-going transients on grounded lines.
What does the "M3/H" suffix indicate in SMBJ36D-M3/H?
The "M3" suffix denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 tin whisker resistance, qualifying it for industrial-grade reliability. The "H" indicates packaging in 7" diameter plastic tape and reel with 750 units per reel. This configuration supports automated SMT assembly and ensures traceable, contamination-controlled handling. The SMBJ36D-M3/H meets UL 497B recognition and complies with Vishay's material categorization per doc#99912.
Can SMBJ36D-M3/H replace SMBJ33D-M3/H in a 36 V system?
Yes, the SMBJ36D-M3/H is the correct replacement for a 36 V nominal system, whereas SMBJ33D-M3/H is rated for 33 V VWM and clamps at 52.5 V. Using SMBJ33D-M3/H in a 36 V application risks premature conduction and increased leakage, as its VWM is below system operating voltage. The SMBJ36D-M3/H's 36 V VWM aligns precisely with typical 36 V DC bus tolerances, ensuring stable non-conduction during normal operation.
What is the thermal resistance and how does it affect PCB layout for SMBJ36D-M3/H?
The SMBJ36D-M3/H has a typical junction-to-ambient thermal resistance (RθJA) of 125 °C/W when mounted on the minimum recommended pad layout per Vishay spec. This value increases significantly without adequate copper area: adding a 5.0 mm × 5.0 mm copper pad reduces RθJA to 100 °C/W. Proper layout directly impacts sustained surge capability-undersized pads cause excessive junction heating during repetitive transients, potentially degrading clamping performance or shortening device life. The SMBJ36D-M3/H requires adherence to Vishay's mounting pad dimensions for rated thermal performance.
