Product details
Overview
SMBJ13CD-M3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 13 V stand-off voltage (VWM), 14.6–15.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamping voltage of 21.2 V at 28.3 A peak surge current. It protects signal lines and power rails in industrial sensor interfaces against ESD and inductive switching transients.
For engineers reviewing the SMBJ13CD-M3/H datasheet, SMBJ13CD-M3/H pinout, SMBJ13CD-M3/H application, or SMBJ13CD-M3/H equivalent, this page delivers verified electrical specs, bidirectional polarity behavior, thermal derating curves, M3 halogen-free RoHS-compliant construction, and direct alternatives for circuit protection design-in.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of transient polarity-critical for AC-coupled or floating signal paths. Its 1.0 W power dissipation at 25 °C ambient and 5.0 W at 50 °C case temperature reflects thermal design constraints when mounted on minimum recommended PCB pad layout.
The device meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C), features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing-ensuring long-term solder joint reliability in industrial-grade applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold |
| VBR (Breakdown) | 14.6–15.7 V at 1 mA - Tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC (Clamping) | 21.2 V at IPPM = 28.3 A - Limits transient voltage seen by downstream ICs during 10/1000 μs surge |
| PPPM | 600 W - Peak pulse power handling per single 10/1000 μs waveform; duty cycle limited to 0.01 % |
| ID (Leakage) | 0.5 μA max at VWM - Minimal standby current avoids loading sensitive analog or low-power circuits |
| RθJA | 125 °C/W - Thermal resistance junction-to-ambient on standard PCB pad; dictates derating above 25 °C |
| TJ max | 150 °C - Maximum junction temperature; requires thermal management for sustained high-power transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA-E3/52 (Vishay) | Same VWM/VBR/PPPM specs but non-M3 variant; lacks JESD 201 Class 2 whisker resistance and halogen-free certification | Suitable for commercial-grade designs where industrial reliability and environmental compliance are not mandated | Select SMBJ13CD-M3/H when MSL Level 1 reflow, RoHS/halogen-free, and whisker resistance are required per IPC-1752 or IATF 16949 |
| P6SMB13CA (Littelfuse) | Identical SMB package, 13 V VWM, 14.4–15.6 V VBR, 600 W PPPM-but rated only to 125 °C TJ max and no MSL Level 1 guarantee | Valid for cost-sensitive consumer electronics with lower thermal stress and less stringent reflow requirements | Choose SMBJ13CD-M3/H for extended temperature operation up to 150 °C and guaranteed lead-free assembly compatibility |
Compared with SMBJ13CA-E3/52 and P6SMB13CA, the SMBJ13CD-M3/H provides verified MSL Level 1 handling, JESD 201 Class 2 whisker resistance, and 150 °C junction rating-making it the preferred choice for industrial and automotive applications demanding long-term solder joint integrity and high-temperature reliability.

FAQ
What does the "CD" suffix indicate in SMBJ13CD-M3/H?
The "CD" suffix denotes a bidirectional Transient Voltage Suppressor. Unlike unidirectional variants (e.g., SMBJ13D), SMBJ13CD-M3/H provides symmetrical clamping for both positive and negative transients-eliminating the need for polarity-aware placement and enabling use in AC-coupled or floating signal paths without external biasing.
Is SMBJ13CD-M3/H compatible with lead-free reflow processes?
Yes, SMBJ13CD-M3/H is qualified to MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the M3 suffix confirms compliance with JESD 201 Class 2 whisker testing-ensuring reliable interconnects in Pb-free assembly lines.
How does the 0.5 μA maximum leakage current at VWM benefit circuit design?
The 0.5 μA maximum reverse leakage current at 13 V stand-off voltage minimizes loading on high-impedance nodes-critical for precision analog front-ends, battery-powered sensors, and current-loop interfaces. For example, in a 4–20 mA transmitter, this leakage introduces less than 0.025 µA error, well within 0.1 % accuracy requirements.
Can SMBJ13CD-M3/H be used in place of a unidirectional SMBJ13D?
No-SMBJ13CD-M3/H is not a drop-in replacement for SMBJ13D. While both share identical VWM, VBR, and PPPM ratings, the unidirectional SMBJ13D requires correct cathode orientation and clamps only negative transients on the anode side. Substituting SMBJ13CD-M3/H may cause unintended conduction in DC-biased circuits due to its bidirectional symmetry.
What is the significance of the 125 °C/W RθJA value for SMBJ13CD-M3/H?
The 125 °C/W junction-to-ambient thermal resistance applies when mounted on Vishay's minimum recommended PCB pad layout. It means that at 1.0 W steady-state dissipation, junction temperature rises 125 °C above ambient-so operation above 25 °C ambient requires derating. For example, at 75 °C ambient, max safe continuous power drops to 0.6 W to stay within 150 °C TJ limit.
