Product details
Overview
SMBJ64CD-M3/I 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/power lines. It features a 64 V stand-off voltage (VWM), 72.2–77.5 V breakdown voltage (VBR) at 1 mA, 102 V maximum clamping voltage (VC) at 5.88 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and telecom line drivers.
For engineers reviewing the SMBJ64CD-M3/I datasheet, SMBJ64CD-M3/I pinout, SMBJ64CD-M3/I application, or SMBJ64CD-M3/I equivalent, key selection criteria include bidirectional clamping capability, ±3.5 % VBR tolerance, low leakage (<0.5 μA at VWM), MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction suitable for automated SMT assembly.
Technical Context
This device operates as a voltage-clamped surge protector: under normal bias it presents high impedance (>1 GΩ), but triggers into low-impedance conduction when reverse voltage exceeds VBR, limiting transient energy via controlled avalanche breakdown. Its bidirectional symmetry enables protection of AC-coupled or differential signal paths without polarity constraints.
The SMBJ64CD-M3/I delivers 600 W peak pulse power handling per 10/1000 μs waveform with thermal resistance RθJA = 125 °C/W (on minimum pad layout) and junction temperature range from –55 °C to +150 °C - enabling reliable operation in industrial and telecom environments where repetitive surges occur at ≤0.01 % duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 72.2 V / 77.5 V at 1 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 102 V at 5.88 A - defines worst-case voltage seen by protected circuit during 600 W transient |
| PPPM | 600 W - peak surge power handled with 10/1000 μs waveform, supporting IEC 61000-4-5 compliance testing |
| ID @ VWM | <0.5 μA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint and MSL Level 1 rating |
| TJ max | +150 °C - supports operation in high-temperature industrial enclosures and under PCB self-heating |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no cathode band marking - terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |

| 600 W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4 kV surge) requirements when applied with proper PCB layout and trace inductance control |
| MSL Level 1, 260 °C reflow | Supports standard lead-free reflow profiles without pre-baking, reducing manufacturing complexity and cost |
| Halogen-free, RoHS-compliant | Fulfills environmental compliance mandates for industrial and telecom equipment sold in EU, China, and North America |
Applications
| Industrial Sensor Interface Protection | Telecom Line Driver Protection |
|---|---|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA loops) from ESD and inductive switching transients in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional TVS placed between signal line and local ground to clamp both positive and negative transients before reaching precision DAC or op-amp output stage. Use Value: Prevents latch-up or permanent damage to 16-bit DACs (e.g., DAC8560) while maintaining <1 nA leakage-induced offset error. |
Use Scenario: Safeguarding RS-485 transceivers (e.g., MAX1487) connected to long outdoor cabling exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Placed across differential pair (A/B) and shield ground to suppress common-mode surges up to 4 kV per IEC 61000-4-5. Use Value: Limits clamped voltage to ≤102 V, keeping transceiver's absolute maximum rating (±12 V common-mode) intact via series impedance coordination. |
| Consumer Audio Signal Path Protection | Automotive Body Control Module (BCM) Power Input |
Use Scenario: Shielding line-out jacks and headphone amplifiers in smart speakers from user-handling ESD events (IEC 61000-4-2 ±8 kV contact). IC Role / Device Role / Timing Role: Connected between audio output and chassis ground to shunt fast ESD pulses away from Class-D amplifier inputs. Use Value: Sub-1 ns response time prevents ESD-induced pop noise or amplifier latch-up, preserving audio fidelity and user experience. |
Use Scenario: Suppressing load-dump transients (SAE J1113-11, up to 120 V/100 ms) on 12 V supply rail feeding microcontroller and CAN transceiver in BCM. IC Role / Device Role / Timing Role: Mounted at PCB entry point between fused 12 V input and bulk capacitor to clamp overshoot before LDO regulators. Use Value: Withstands 600 W peak power, enabling use without parallel MOVs - reduces BOM count and board space vs. hybrid solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA-E3/52 (Vishay) | Same VWM/VBR/VC specs; differs in packaging (tape-and-reel quantity 2500 vs. 3200) and JEDEC-compliant marking (no "M3/I" suffix) | No halogen-free or whisker-tested qualification; not rated for industrial-grade reliability screening | Select SMBJ64CD-M3/I when M3-grade matte tin plating and JESD201 Class 2 whisker resistance are required for long-life deployments. |
| 1.5SMC64CA (ON Semiconductor) | Same SMB package and bidirectional 64 V rating, but higher VC = 103 V at 5.8 A and wider VBR tolerance (±5 %) | Lacks MSL Level 1 rating; requires baking prior to reflow if exposed to ambient >60 % RH for >24 hrs | Choose SMBJ64CD-M3/I for automated SMT lines with zero-bake requirements and tighter VBR matching in multi-channel designs. |
Compared with SMBJ64CA-E3/52 and 1.5SMC64CA, the SMBJ64CD-M3/I provides guaranteed halogen-free composition, JESD201 Class 2 whisker resistance, and tighter ±3.5 % VBR tolerance - critical for high-reliability industrial and telecom systems where field failure root cause must exclude metallurgical or parametric drift issues.

FAQ
What is the clamping voltage of SMBJ64CD-M3/I at its rated peak pulse current?
The SMBJ64CD-M3/I has a maximum clamping voltage (VC) of 102 V when subjected to its peak pulse current (IPPM) of 5.88 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is SMBJ64CD-M3/I suitable for bidirectional signal line protection?
Yes, SMBJ64CD-M3/I is explicitly designed as a bidirectional TVS diode, indicated by the "CD" suffix. Its symmetrical breakdown behavior in both polarities allows placement across AC-coupled or differential signal pairs (e.g., RS-485, USB D+/D−) without concern for orientation - eliminating the need for dual unidirectional devices or polarity-aware layout routing.
Does SMBJ64CD-M3/I meet lead-free reflow requirements?
Yes, SMBJ64CD-M3/I is qualified to MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102 solderability standards, and the M3 suffix confirms it passes JESD201 Class 2 whisker testing - making it fully compatible with standard lead-free SMT assembly processes without pre-baking.
How does the ±3.5 % VBR tolerance of SMBJ64CD-M3/I impact system-level surge design?
The ±3.5 % VBR tolerance (72.2–77.5 V at 1 mA) ensures consistent clamping onset across production units, reducing the need for over-designing series impedance or derating protected ICs. For example, in a 64 V system, this tight window guarantees clamping initiates before reaching 77.5 V - allowing precise coordination with upstream fuses or downstream overvoltage lockout circuits in safety-critical applications.
Can SMBJ64CD-M3/I be used in place of a unidirectional SMBJ64D-M3/I?
No - SMBJ64CD-M3/I is bidirectional and lacks a cathode band, while SMBJ64D-M3/I is unidirectional with defined polarity. Substituting them requires verifying circuit topology: bidirectional use cases (e.g., AC lines, differential buses) require SMBJ64CD-M3/I, whereas DC rails referenced to ground typically need unidirectional devices like SMBJ64D-M3/I to avoid forward-conduction during normal operation.
