Product details
Overview
SMB8J16C-E3/5B from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for robust overvoltage protection on signal and power lines. It features a 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 30.8 A peak pulse current (IPPM), and 800 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB8J16C-E3/5B datasheet, SMB8J16C-E3/5B pinout, SMB8J16C-E3/5B application, or SMB8J16C-E3/5B equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling suppression of positive and negative transients without polarity dependency. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while the DO-214AA package supports high surge current handling with minimal parasitic inductance.
The device complies with ANSI/IEEE C62.35 for transient suppression standards and is rated for -55 °C to +150 °C operating junction temperature. It meets MSL level 1 per J-STD-020 and passes JESD 201 class 1A whisker testing, confirming suitability for automotive-grade reflow and long-term reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VBR (min/max) | 17.8 V / 19.7 V - Breakdown occurs within this range at 1.0 mA test current; ensures predictable turn-on during fast transients. |
| VC @ IPPM | 26.0 V - Clamped voltage at 30.8 A peak pulse current; limits downstream IC stress during 800 W surges. |
| PPPM | 800 W - Peak pulse power rating with 10/1000 µs waveform; validates protection against ISO 7637-2 Pulse 1/2/5a/b events. |
| ID @ VWM | <1.0 µA - Reverse leakage at stand-off voltage; minimizes standby power loss and avoids false triggering. |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; enables efficient heat transfer to PCB copper, supporting sustained surge duty cycles. |
| AEC-Q101 | Qualified - Certified for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
Pinout & Package
DO-214AA (SMB) surface-mount package: molded epoxy case with matte tin-plated leads, 0.220" (5.59 mm) overall length, 0.155" (3.94 mm) body width, cathode band absent (bi-directional symmetry).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No polarity marking; either terminal serves as anode or cathode depending on transient polarity - simplifies layout and eliminates orientation errors. |
| Case (body) | Thermal and mechanical interface | Direct thermal path to PCB copper pads; requires minimum 5.0 mm × 5.0 mm pad area per terminal per datasheet fig. 2 for rated PPPM performance. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., CAN, LIN, RS-485) without external polarity management. |
| AEC-Q101 qualification | Validates reliability for automotive under-hood and chassis-mounted modules subject to thermal cycling, vibration, and humidity. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage drift over time and temperature - critical for long-life industrial deployments. |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 260 °C peak without moisture-induced popcorning or delamination. |
| Low incremental surge resistance | Minimizes voltage overshoot during sub-microsecond transients, improving protection margin for sensitive 3.3 V/5 V logic interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Same VWM (16 V), VC (26.0 V), and DO-214AA package; lower PPPM (600 W vs. 800 W) and IPPM (22.5 A vs. 30.8 A). | Rated for less severe surge environments (e.g., consumer-grade I/O); not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification or higher surge immunity needs. |
| SMCJ16CA | Same VWM and bi-directionality but in larger DO-214AB (SMC) package; higher PPPM (1500 W), IPPM (62.0 A), and RθJA (35 °C/W). | Requires more PCB area; better suited for high-energy industrial power line protection than space-constrained automotive modules. | Choose when system-level surge tests exceed 800 W or thermal dissipation demands exceed DO-214AA capability. |
Compared with SMBJ16CA and SMCJ16CA, SMB8J16C-E3/5B uniquely balances AEC-Q101 qualification, 800 W surge capacity, and compact DO-214AA footprint - making it optimal for automotive sensor nodes and industrial edge controllers where board space, reliability, and standardized testing are jointly constrained.

FAQ
What is the clamping voltage of SMB8J16C-E3/5B at its rated peak pulse current?
The SMB8J16C-E3/5B has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPPM) of 30.8 A with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream circuitry remains below destructive voltage thresholds during standardized surge events. The SMB8J16C-E3/5B maintains this clamping performance across its full operating temperature range.
Is SMB8J16C-E3/5B suitable for automotive applications?
Yes, SMB8J16C-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control, body electronics, and ADAS sensor interfaces. Its construction - glass-passivated junction, MSL Level 1 rating, and JESD 201 class 1A whisker resistance - meets stringent automotive reliability requirements. The SMB8J16C-E3/5B datasheet confirms qualification per AEC-Q101 Rev D test conditions.
How does the bi-directional configuration of SMB8J16C-E3/5B affect PCB layout?
The SMB8J16C-E3/5B has no polarity marking and functions identically in either orientation, eliminating orientation-dependent placement errors and simplifying automated assembly. Layout requires symmetrical 5.0 mm × 5.0 mm copper pads per terminal per Vishay's recommended mounting pad layout - no dedicated anode/cathode routing is needed. This symmetry makes SMB8J16C-E3/5B ideal for protecting differential or floating signal paths like CAN or LIN buses.
What is the maximum operating temperature for SMB8J16C-E3/5B?
The SMB8J16C-E3/5B has a maximum operating junction temperature (TJ) of +150 °C and a storage temperature range of -55 °C to +150 °C. Its thermal resistance from junction to lead (RθJL) is 20 °C/W, enabling effective heat transfer to the PCB when mounted on specified copper areas. This allows the SMB8J16C-E3/5B to sustain repeated surge events in under-hood automotive environments and high-ambient industrial enclosures.
Does SMB8J16C-E3/5B meet RoHS and halogen-free requirements?
Yes, SMB8J16C-E3/5B carries the "E3" suffix, indicating full RoHS compliance per Directive 2011/65/EU and halogen-free status per JEDEC JS709A. The matte tin-plated leads conform to J-STD-002 and JESD 22-B102 solderability standards, and the molding compound meets UL 94 V-0 flammability rating. These certifications are documented in Vishay's material category policy (doc# 99912).
