Product details
Overview
SMBJ5.0C-E3/5B 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 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤9.2 V at 65.2 A peak surge current - protecting MOSFETs, ICs, and sensor interfaces in industrial power supplies and telecom line cards.
For engineers reviewing the SMBJ5.0C-E3/5B datasheet, SMBJ5.0C-E3/5B pinout, SMBJ5.0C-E3/5B application, or SMBJ5.0C-E3/5B equivalent, key selection criteria include unidirectional polarity, 9.2 V clamping voltage at rated IPPM, RoHS-compliant matte tin plating, MSL Level 1 rating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a fast-acting shunt protector: under normal bias it presents high impedance (>800 µA leakage at 5.0 V), but triggers into low-impedance conduction when transient voltage exceeds VBR, clamping the line to ≤9.2 V within <1 ns. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Rated for -55 °C to +150 °C junction temperature, it delivers 600 W peak pulse power with 0.01% duty cycle, derated linearly above 25 °C ambient per Fig. 2. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation without heatsinking on standard PCB copper areas.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC working margin. |
| VBR @ IT = 10 mA | 6.4–7.07 V - Breakdown onset range; ensures reliable triggering above system nominal voltage with margin. |
| VC @ IPPM = 65.2 A | ≤9.2 V - Clamped voltage during 600 W transient; determines maximum stress imposed on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling (10/1000 µs waveform); supports robust protection against lightning-induced surges and inductive switching spikes. |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); enables survival of brief overcurrent events in power rail applications. |
| Junction Temp Range | -55 °C to +150 °C - Enables deployment in automotive engine bays, industrial motor drives, and outdoor telecom enclosures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.155" footprint; compatible with J-STD-020 reflow profiles up to 260 °C peak. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads; cathode indicated by band marking on unidirectional devices. Meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point under forward bias; connected to lower-potential side of protected line. | Accepts surge current during clamping; must be routed with low-inductance trace to minimize overshoot. |
| Cathode | Current exit point under forward bias; marked with band; connected to higher-potential side (e.g., VCC or signal return). | Provides reference for clamping action; ties to local ground or supply rail to define clamp voltage baseline. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) without external series impedance. |
| Clamping voltage ≤9.2 V at 65.2 A | Protects 5 V logic rails and USB/RS-485 transceivers without violating absolute maximum ratings. |
| Response time <1 ns | Engages before ESD or fast transients damage sensitive gate oxides in MOSFETs or CMOS inputs. |
| MSL Level 1, 260 °C peak reflow | Eliminates pre-baking requirement; compatible with standard lead-free assembly processes. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets global environmental compliance mandates without performance trade-offs or cost premium. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/5B | Unidirectional; identical VWM, VBR, and VC; same SMB package and RoHS/E3 compliance. | No functional difference; "A" and "C" suffixes denote identical electrical specs per Vishay documentation (both listed in same SMBJ5.0A-C family table). | Select SMBJ5.0A-E3/5B only if legacy BOM references "A" suffix; otherwise SMBJ5.0C-E3/5B is direct functional match. |
| SMCJ5.0A-E3/57T | Same VWM/VBR/VC, but SMC (DO-214AB) package: 20 % larger footprint, 1.5× higher thermal mass, RθJA = 40 °C/W. | Better thermal dissipation for high-duty-cycle surges; requires PCB layout change due to larger pad pattern and 0.275" × 0.215" outline. | Choose SMCJ5.0A-E3/57T only when 600 W pulses occur >0.01 % duty cycle or ambient exceeds 85 °C; not drop-in replacement. |
Compared with SMBJ5.0A-E3/5B, the original SMBJ5.0C-E3/5B offers identical protection performance in the same compact SMB footprint; versus SMCJ5.0A-E3/57T, it trades thermal headroom for space-constrained designs where board area is prioritized over sustained surge repetition.

FAQ
What is the polarity configuration of SMBJ5.0C-E3/5B?
SMBJ5.0C-E3/5B is a unidirectional TVS diode: it conducts only in reverse bias above VBR, with the cathode identified by a band marking. This configuration provides asymmetric clamping ideal for DC power rails and single-ended signal lines where polarity is fixed, unlike bidirectional variants (e.g., SMBJ5.0CA) used for AC or differential signals.
Does SMBJ5.0C-E3/5B meet automotive qualification standards?
SMBJ5.0C-E3/5B is RoHS-compliant commercial-grade (E3 suffix) and does not carry AEC-Q101 qualification. For automotive use, select the HE3 variant (e.g., SMBJ5.0CHE3_B/I), which adds AEC-Q101 stress testing and extended temperature validation while retaining identical electrical specs and SMB packaging.
What is the maximum clamping voltage of SMBJ5.0C-E3/5B under rated surge conditions?
The maximum clamping voltage (VC) of SMBJ5.0C-E3/5B is 9.2 V when subjected to its rated peak pulse current of 65.2 A (10/1000 µs waveform). This value is guaranteed per Vishay's datasheet Table 1 and defines the upper voltage limit imposed on protected circuitry during transient events.
Can SMBJ5.0C-E3/5B be used in bidirectional signal protection?
No - SMBJ5.0C-E3/5B is unidirectional and unsuitable for bidirectional signal lines like USB D+/D− or RS-485 A/B. For such applications, use the bidirectional variant SMBJ5.0CA-E3/5B, which clamps symmetrically in both directions and lacks polarity marking, ensuring protection regardless of signal swing direction.
What PCB pad layout is recommended for optimal thermal performance of SMBJ5.0C-E3/5B?
Vishay specifies mounting SMBJ5.0C-E3/5B on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and 100 °C/W thermal resistance. Reducing pad size increases junction temperature and de-rates peak power; thermal vias under pads further improve heat dissipation in high-ambient environments.
