Product details
Overview
SMBJ13A/54 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1.0 mA, 21.5 V maximum clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ13A/54 datasheet, SMBJ13A/54 pinout, SMBJ13A/54 application, or SMBJ13A/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and AEC-Q101-qualified variants for automotive-grade deployment.
Technical Context
The SMBJ13A/54 operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1 ps) to ESD and lightning-induced surges. Its low incremental surge resistance (rd) ensures stable clamping during repetitive 10/1000 µs transients at 0.01% duty cycle, while its MSL Level 1 moisture sensitivity rating supports lead-free reflow up to 260 °C peak.
Thermal design relies on RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), requiring minimum 5.0 mm × 5.0 mm copper pads per terminal for rated 600 W pulse handling. The cathode band denotes polarity; no marking applies to bidirectional versions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Bidirectional variant; symmetric VBR = 14.4–15.9 V in both polarities; same VC, PPPM, and package. | Required for AC-coupled signal lines (e.g., RS-485, USB D+/D−) where polarity reversal occurs. | Select SMBJ13CA only when protecting balanced differential pairs or AC rails; not interchangeable with SMBJ13A/54 in unidirectional DC circuits. |
| SMAJ13A | Lower PPPM = 400 W; same VWM/VBR/VC; SMA (DO-214AC) package with smaller 4.5 mm × 2.7 mm footprint. | Suitable for space-constrained consumer designs where 400 W surge margin suffices (e.g., USB-C PD adapters). | Choose SMAJ13A only if board area is critical and surge threat level is limited to IEC 61000-4-5 Level 2; not recommended for industrial 600 W requirements. |
Compared with SMBJ13CA and SMAJ13A, the SMBJ13A/54 provides optimal balance of 600 W surge capacity, SMB package manufacturability, and 13 V system compatibility - making it the preferred choice for industrial DC power rail protection where unidirectional clamping and proven thermal performance are required.

FAQ
What is the maximum clamping voltage of SMBJ13A/54 under rated surge conditions?
The SMBJ13A/54 exhibits a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 27.9 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 09-Jan-2024, Document Number 88392. It defines the upper voltage limit imposed on protected circuitry during worst-case transient events, ensuring compatibility with 15 V logic and power stages.
Is SMBJ13A/54 RoHS-compliant and halogen-free?
Yes, SMBJ13A/54 is available in multiple compliance variants: base part number ending in "-E3" is RoHS-compliant (commercial grade), while "-M3" denotes halogen-free and RoHS-compliant construction. Both meet JESD201 Class 2 whisker resistance and UL 94 V-0 flammability standards. The specific suffix for SMBJ13A/54 must be verified against ordering codes in the Vishay datasheet Table "ORDERING INFORMATION".
Can SMBJ13A/54 be used in automotive applications?
Yes - the AEC-Q101-qualified version of SMBJ13A/54 is designated with "HE3" (RoHS-compliant) or "HM3" (halogen-free + RoHS) suffixes, such as SMBJ13AHE3_B/H. These variants undergo stress testing per AEC-Q101 Rev D, including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST), qualifying them for under-hood and body electronics use.
What is the thermal resistance from junction to ambient for SMBJ13A/54?
The typical thermal resistance from junction to ambient (RθJA) for SMBJ13A/54 is 100 °C/W, measured on a standard 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad layout per terminal. This value assumes no additional heatsinking and is critical for calculating allowable power dissipation at elevated ambient temperatures using the derating curve in Figure 2 of the Vishay datasheet.
How does SMBJ13A/54 differ from SMBJ13A without the "/54" suffix?
The "/54" suffix in SMBJ13A/54 indicates a specific tape-and-reel packaging configuration - typically 750 units per 7-inch reel (package code "52") or 3200 units per 13-inch reel (package code "5B"), as defined in Vishay's ordering information table. Electrically and mechanically, SMBJ13A/54 is identical to SMBJ13A; the suffix reflects logistics and handling format, not functional differentiation.
