Product details
Overview
SMBJ13C-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in industrial sensor interfaces and automotive body control modules.
For engineers reviewing the SMBJ13C-E3/52 datasheet, SMBJ13C-E3/52 pinout, SMBJ13C-E3/52 application, or SMBJ13C-E3/52 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and RoHS-compliant commercial-grade sourcing details - all aligned to Vishay Document #88392 (Rev. 09-Jan-2024).
Technical Context
This TVS diode operates as a unidirectional clamping device, conducting only during reverse-biased transients above its breakdown threshold while remaining high-impedance under normal 13 V DC operation. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 µA at VWM), critical for low-power sensor supply rail protection.
Thermal design relies on RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), enabling reliable operation up to TJ = +150 °C when mounted on 5.0 mm × 5.0 mm copper pads per Vishay's recommended layout. The device meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - maximum continuous reverse operating voltage before significant conduction begins; defines upper limit of protected circuit's nominal DC rail. |
| VBR (Breakdown Voltage) | 14.4–15.9 V at IT = 1 mA - precise voltage threshold where avalanche conduction initiates; ensures predictable clamping onset. |
| VC (Clamping Voltage) | 21.5 V at IPPM = 27.9 A (10/1000 µs) - maximum voltage seen by downstream ICs during worst-case surge; limits stress on 24 V-tolerant receivers. |
| PPPM (Peak Pulse Power) | 600 W - surge energy handling capability under standardized 10/1000 µs waveform; supports IEC 61000-4-5 Level 3 (1 kV/2 kV) compliance. |
| IPPM (Peak Pulse Current) | 27.9 A - maximum non-repetitive surge current the device safely clamps without degradation; validated per Fig. 1 & 2 in Doc. #88392. |
| TJmax | +150 °C - maximum junction temperature; enables use in under-hood automotive environments and industrial enclosures without forced cooling. |
| Package | SMB (DO-214AA) - surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and reflow soldering per J-STD-020. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band marking on unidirectional variant SMBJ13C-E3/52.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to circuit ground or return path; completes clamping loop during transient events. |
| Cathode | High-side connection point | Connected to protected line (e.g., 13 V supply or CAN_H); conducts avalanche current when VAK exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables single-device protection against severe lightning-induced surges per IEC 61000-4-5, eliminating need for cascaded protection stages. |
| 21.5 V clamping at 27.9 A | Keeps downstream 24 V-rated microcontrollers and transceivers within safe operating area during 1 kV surge events. |
| 1.0 µA max reverse leakage at VWM | Minimizes standby power loss in battery-powered sensor nodes and avoids false triggering in high-impedance analog inputs. |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free assembly processes without pre-baking or special handling, reducing manufacturing overhead. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental regulations while maintaining cost-effective BOM positioning for industrial and consumer applications. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM (13 V), identical VBR (14.4–15.9 V), but lower IPPM = 27.9 A and same VC = 21.5 V; no "C" suffix denotes standard unidirectional variant. | Functionally identical clamping behavior; "C" suffix in SMBJ13C-E3/52 indicates Vishay's enhanced reliability screening per internal qualification. | Select SMBJ13C-E3/52 for higher-reliability deployments requiring extended lifetime under repeated surge stress. |
| SMCJ13A-E3/52 | Same VWM/VBR/VC, but in larger SMC (DO-214AB) package with 1500 W PPPM; RθJA = 35 °C/W vs. 100 °C/W for SMBJ. | Higher surge margin for infrequent but extreme events (e.g., direct lightning coupling); requires larger PCB area and different pad layout. | Choose SMCJ13A-E3/52 only if system-level testing confirms need for >600 W clamping capacity and board space permits SMC footprint. |
Compared with SMBJ13A-E3/52, the SMBJ13C-E3/52 offers identical electrical specs with enhanced process screening, while SMCJ13A-E3/52 trades compact SMB size for 2.5× higher pulse power - making SMBJ13C-E3/52 optimal for space-constrained 13 V rail protection where reliability under cyclic stress is prioritized.

FAQ
What is the clamping voltage of SMBJ13C-E3/52 at its rated peak pulse current?
The SMBJ13C-E3/52 has a maximum clamping voltage (VC) of 21.5 V at IPPM = 27.9 A using the 10/1000 µs waveform. This value is measured per Vishay Document #88392 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - ensuring compatibility with 24 V-rated interface ICs and microcontrollers.
Is SMBJ13C-E3/52 suitable for bidirectional signal line protection?
No, SMBJ13C-E3/52 is a unidirectional TVS diode, intended for DC power rail or single-polarity signal protection. For bidirectional applications such as RS-485 or USB data lines, Vishay recommends the SMBJ13CA-E3/52 variant, which provides symmetrical clamping in both directions and uses the "CA" suffix per the datasheet's device coding table.
What does the "C" suffix in SMBJ13C-E3/52 signify?
The "C" suffix in SMBJ13C-E3/52 indicates Vishay's enhanced reliability screening level beyond standard commercial qualification - including additional burn-in, parameter verification, and lot acceptance testing. It is not a package or polarity designation, and does not alter VWM, VBR, or VC values compared to SMBJ13A-E3/52.
Does SMBJ13C-E3/52 meet automotive AEC-Q101 requirements?
No, SMBJ13C-E3/52 is a commercial-grade part with E3 suffix (RoHS-compliant, non-automotive). For AEC-Q101 qualified versions, Vishay offers SMBJ13HE3_X (e.g., SMBJ13HE3_A), which carries the "HE3" suffix and is explicitly listed in the ordering table as AEC-Q101 qualified per Note (1) on page 3 of Document #88392.
What is the thermal resistance from junction to ambient for SMBJ13C-E3/52?
The typical junction-to-ambient thermal resistance (RθJA) for SMBJ13C-E3/52 is 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Thermal Characteristics table of Vishay Document #88392. This value assumes standard FR-4 PCB construction and natural convection cooling.
