Product details
Overview
SMB8J10C-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 of signal and power lines. It features 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 47.1 A peak pulse current (IPPM), and 800 W peak pulse power (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect automotive sensor interfaces against ESD and load-dump transients.
For engineers reviewing the SMB8J10C-E3/5B datasheet, SMB8J10C-E3/5B pinout, SMB8J10C-E3/5B application, or SMB8J10C-E3/5B equivalent, key selection criteria include bi-directional clamping capability, low leakage (<1.0 µA at VWM), RoHS-compliant matte tin terminations, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically across both polarities, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance under repetitive transient stress.
The device complies with ANSI/IEEE C62.35 for transient suppression and meets AEC-Q101 stress test requirements for automotive under-hood applications. Thermal resistance is characterized at RθJA = 72 °C/W (typ.) and RθJL = 20 °C/W (typ.), supporting reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin for 12 V automotive systems. |
| VBR (min/max) | 11.1 V / 12.3 V - Breakdown occurs within this range at 1.0 mA test current; ensures predictable turn-on during transients. |
| VC @ IPPM | 17.0 V - Clamped voltage at 47.1 A peak pulse current; limits downstream IC stress during 800 W surges. |
| IPPM | 47.1 A - Peak surge current survivable with 10/1000 µs waveform; validated on 5.0 mm × 5.0 mm copper pads. |
| ID @ VWM | <1.0 µA - Reverse leakage at rated stand-off voltage; minimizes standby power loss in battery-sensitive designs. |
| TJ max. | 150 °C - Maximum junction temperature; supports under-hood deployment in automotive ECUs and ADAS modules. |
| Package | DO-214AA (SMB) - Surface-mount package with 2.13–2.44 mm body width; compatible with standard SMB footprint and reflow profiles. |
Pinout & Package
DO-214AA (SMB) package: bi-directional device with no polarity marking; symmetrical terminals suitable for either orientation in PCB layout. Cathode band absent per bi-directional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals serve identical roles; bidirectional clamping enables use on AC lines, differential pairs, or unmarked PCB traces. |
| Case (exposed cathode pad not present) | Thermal and mechanical interface | No thermal pad; heat dissipation relies on soldered leads and adjacent copper; requires minimum 5.0 mm × 5.0 mm pad per terminal per datasheet fig. 2. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling, humidity bias, and mechanical shock per JESD22 standards. |
| Glass passivated junction | Ensures long-term stability of VBR and low parameter drift over lifetime, critical for safety-critical protection circuits. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking; compatible with high-volume SMT assembly at peak 260 °C. |
| RoHS-compliant matte tin plating | Meets J-STD-002 and JESD22-B102 solderability; passes JESD201 Class 1A whisker testing for reliability in vibration-prone systems. |
| Low clamping ratio (VC/VBR ≈ 1.53) | Indicates efficient energy diversion with minimal voltage overshoot-critical for protecting 12 V logic interfaces and CAN transceivers. |
Applications
| Automotive Sensor Interface Protection | Industrial RS-485 Transceiver Protection |
|---|---|
|
Use Scenario: Protecting LIN/CAN bus nodes and analog sensor outputs (e.g., pressure, temperature) in engine control units exposed to ISO 7637-2 pulses and ESD events. IC Role / Device Role / Timing Role: Bi-directional clamping element placed directly at connector entry point to shunt transients before reaching MCU I/O or analog front-end. Use Value: Limits induced voltage to ≤17.0 V during 47.1 A surges, preserving signal integrity and preventing latch-up in 12 V-rated transceivers. |
Use Scenario: Safeguarding half-duplex RS-485 transceivers in factory automation PLCs subjected to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Primary line protector on A/B differential pair; operates symmetrically to clamp both positive and negative transients without polarity dependency. Use Value: Maintains data integrity by clamping common-mode surges to <17.0 V while adding <0.5 pF capacitance at 0 V bias-no signal distortion at 10 Mbps. |
| Consumer USB Port ESD Protection | DC Power Rail Surge Suppression |
|
Use Scenario: Secondary-level ESD protection on USB 2.0 D+/D− lines in automotive infotainment head units, supplementing integrated I/O ESD cells. IC Role / Device Role / Timing Role: Board-level TVS placed after connector, providing >30 kV contact ESD immunity per IEC 61000-4-2. Use Value: Responds in <1 ns to divert >15 A ESD currents, reducing voltage seen by PHY to safe levels without affecting 480 Mbps signaling. |
Use Scenario: Suppressing load-dump transients (ISO 16750-2 Pulse 5a) on 12 V supply rails feeding ADAS cameras and radar modules. IC Role / Device Role / Timing Role: Parallel-connected transient absorber across input capacitor, activated only during overvoltage events above 10 V. Use Value: Absorbs up to 800 W for 1 ms without failure, limiting rail voltage to 17.0 V and preventing brownout or reset of downstream PMICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/5B | Same DO-214AA package and 10 V VWM, but lower PPPM (600 W vs. 800 W) and higher VC (19.9 V vs. 17.0 V). | Less effective clamping margin for fast-rising 12 V system transients; suitable where lower surge energy is expected. | Select SMBJ10CA-E3/5B only if design validates <19.9 V clamping is acceptable and peak surge energy remains below 600 W. |
| 1.5KE10CA | Through-hole DO-201 package, same 10 V VWM and bi-directionality, but higher VC (19.0 V) and larger footprint. | Not suitable for high-density SMT layouts; requires manual or wave soldering; less ideal for automotive vibration environments. | Choose 1.5KE10CA only when board space allows through-hole mounting and legacy manufacturing processes are in place. |
Compared with SMBJ10CA-E3/5B and 1.5KE10CA, SMB8J10C-E3/5B delivers superior clamping performance (17.0 V) and higher surge capacity (800 W) in the compact DO-214AA package-making it optimal for space-constrained, high-reliability automotive and industrial SMT designs requiring tight voltage margins.
