Product details
Overview
SMBJ13C-E3/5B 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 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (VBR at 1 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 motor drives.
For engineers reviewing the SMBJ13C-E3/5B datasheet, SMBJ13C-E3/5B pinout, SMBJ13C-E3/5B application, or SMBJ13C-E3/5B equivalent, key selection criteria include unidirectional polarity, 13 V stand-off rating, 21.5 V clamping performance under 27.9 A surge, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device, conducting only when reverse voltage exceeds its breakdown threshold (14.4–15.9 V), thereby shunting transient energy to ground while limiting downstream voltage to ≤21.5 V. Its glass-passivated junction ensures stable leakage (<1.0 µA at 13 V) and fast response time (<1.0 ns).
Thermal design relies on low thermal resistance: RθJL = 20 °C/W (junction-to-lead) enables effective heat dissipation during repetitive surges, while RθJA = 100 °C/W (junction-to-ambient) assumes minimum recommended PCB pad layout per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - maximum continuous reverse operating voltage before conduction begins |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - precise clamping initiation threshold under standardized test conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/5B | Same VWM (13 V), identical VBR (14.4–15.9 V), identical VC (21.5 V), same SMB package and RoHS compliance | No functional difference; "A" suffix denotes standard commercial-grade unidirectional variant (vs. "C" which indicates same specification per Vishay's internal revision coding) | Select SMBJ13A-E3/5B if sourcing legacy BOMs or distributors list it as primary stock; functionally interchangeable. |
| SMCJ13A-E3/57T | Higher power rating (1500 W), larger SMC (DO-214AB) package, same VWM/VBR/VC, higher IPPM (69.4 A) | Used where higher surge repetition or longer pulse durations occur; requires larger PCB footprint and different thermal pad layout | Choose SMCJ13A-E3/57T only when system-level testing confirms >600 W surge exposure; otherwise SMBJ13C-E3/5B optimizes space and cost. |
Compared with SMBJ13A-E3/5B, SMBJ13C-E3/5B offers identical electrical protection but reflects Vishay's updated manufacturing revision; versus SMCJ13A-E3/57T, it trades surge headroom for compactness and lower thermal mass - ideal for space-constrained 24 V industrial I/O modules.

FAQ
What is the standoff voltage rating of SMBJ13C-E3/5B?
The SMBJ13C-E3/5B has a standoff voltage (VWM) of 13 V, meaning it remains non-conductive under continuous reverse bias up to this level. This value is confirmed in Vishay's datasheet Document Number 88392, Table on page 2, and defines the maximum operating voltage before breakdown begins. The SMBJ13C-E3/5B maintains <1.0 µA leakage current at this voltage, ensuring minimal power loss in always-on circuits.
Does SMBJ13C-E3/5B meet automotive qualification standards?
The SMBJ13C-E3/5B is RoHS-compliant and commercial-grade; it is not AEC-Q101 qualified. For automotive use, Vishay specifies variants with HE3 or HM3 suffixes (e.g., SMBJ13AHE3_B). The SMBJ13C-E3/5B is intended for industrial and consumer applications where extended temperature cycling and vibration testing are not mandated. Always verify qualification status using the full part number and Vishay's official ordering matrix.
What is the maximum clamping voltage of SMBJ13C-E3/5B under surge conditions?
The SMBJ13C-E3/5B clamps to a maximum of 21.5 V when subjected to its rated peak pulse current of 27.9 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and is critical for ensuring protected ICs or MOSFETs remain within absolute maximum ratings. The SMBJ13C-E3/5B achieves this with low incremental surge resistance, minimizing voltage overshoot during fast-rising transients.
Can SMBJ13C-E3/5B be used in bidirectional protection circuits?
No - SMBJ13C-E3/5B is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMBJ13CA). Using SMBJ13C-E3/5B in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always match polarity designation to system grounding architecture.
What PCB pad layout is recommended for optimal thermal performance of SMBJ13C-E3/5B?
Vishay specifies mounting SMBJ13C-E3/5B on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated power dissipation and thermal resistance (RθJA = 100 °C/W). Reducing pad size increases junction temperature and de-rates pulse power capability. The SMBJ13C-E3/5B datasheet Figure 2 provides derating curves showing >50% power loss at TA = 100 °C without adequate copper area.
