Product details
Overview
SMB8J10CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 10 A peak pulse current (IPPM), and 800 W peak pulse power (PPPM) with 10/1000 μs waveform - optimized for automotive sensor interface and industrial I/O protection.
For engineers reviewing the SMB8J10CAHE3_A/H datasheet, SMB8J10CAHE3_A/H pinout, SMB8J10CAHE3_A/H application, or SMB8J10CAHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, bidirectional polarity, low clamping ratio (VC/VWM = 1.7), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with bidirectional symmetry enabling suppression of both positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM).
Thermal performance is defined by RθJA = 72 °C/W and RθJL = 20 °C/W, supporting reliable operation up to TJ = +150 °C. The device meets MSL Level 1 per J-STD-020 and is rated for 8.3 ms half-sine surge currents up to 100 A in unidirectional variants - though SMB8J10CAHE3_A/H itself is bidirectional and not rated for IFSM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins; defines safe signal line bias margin |
| VBR min / max | 11.1 V / 12.3 V at IT = 1.0 mA - guaranteed breakdown onset range ensures consistent trigger threshold across production lots |
| VC @ IPPM | 17.0 V at IPPM = 10 A (10/1000 μs) - clamping voltage limits downstream IC stress during ESD or load-switching surges |
| PPPM | 800 W - peak transient energy handling capacity under standardized surge waveform; enables robust protection in automotive environments |
| ID @ VWM | <1.0 μA - ultra-low leakage preserves signal integrity and battery life in always-on sensor circuits |
| Polarity | Bidirectional - protects against voltage transients of either polarity without requiring orientation during placement |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per AEC specification |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with matte tin-plated leads; dimensions 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Reference terminal for bidirectional conduction | No functional polarity - marking is for mechanical orientation only; terminals are symmetric and interchangeable |
| Anode | Reference terminal for bidirectional conduction | Electrically identical to cathode; device conducts identically in both directions above VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics including engine control units, ADAS sensors, and body electronics |
| Low clamping ratio (VC/VWM = 1.7) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio TVS devices |
| Glass-passivated junction | Ensures stable VBR over time and temperature, with reduced parameter drift in harsh environments |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free reflow profiles without moisture-related delamination risk |
| RoHS-compliant & halogen-free option available | HE3 suffix denotes RoHS compliance; HM3 suffix adds halogen-free formulation for stringent environmental programs |
Applications
| Automotive Sensor Interface | Industrial Digital I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from ISO 7637-2 pulses and ESD events in vehicle cabins. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between connector and transceiver input pins. Use Value: Limits transient voltage to ≤17.0 V during 10/1000 μs surges, preventing latch-up or damage to 3.3 V/5 V automotive ICs. |

IC Role / Device Role / Timing Role: First-stage protector on RJ-45 jack side, upstream of gas discharge tube (GDT) secondary stage. Use Value: Responds in <1 ns to limit let-through voltage before GDT fires, reducing overall system clamping level. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CAHE3_A/H | Same SMB package and 10 V VWM, but lower PPPM (600 W vs. 800 W) and higher VC (20.0 V vs. 17.0 V) | Limited to lower-energy surge environments; less margin for ISO 7637-2 Pulse 5a testing | Select when cost sensitivity outweighs need for highest surge headroom |
| 1.5SMC10CA | Higher-power SMC package (1500 W PPPM), same VWM/VC specs, larger footprint (7.11 mm × 6.22 mm) | Requires PCB layout change; suited for primary-level protection where space permits | Choose when system-level surge requirements exceed 800 W and board area allows SMC |
Compared with SMBJ10CAHE3_A/H and 1.5SMC10CA, SMB8J10CAHE3_A/H delivers superior clamping performance (17.0 V vs. 20.0 V) in the compact SMB footprint, making it optimal for space-constrained automotive and industrial modules where both size and low let-through voltage are critical.

FAQ
What is the maximum clamping voltage of SMB8J10CAHE3_A/H under standard test conditions?
The SMB8J10CAHE3_A/H has a maximum clamping voltage (VC) of 17.0 V when subjected to a 10 A peak pulse current with a 10/1000 μs waveform. This value is measured at TJ = 25 °C and reflects the upper limit of voltage let-through during surge events - critical for ensuring protected ICs remain within absolute maximum ratings.
Is SMB8J10CAHE3_A/H qualified for automotive applications?
Yes, SMB8J10CAHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock - validating its suitability for under-hood and cabin-mounted automotive electronics.
Does SMB8J10CAHE3_A/H have polarity markings, and how does that affect circuit design?
SMB8J10CAHE3_A/H is bidirectional and carries a cathode band solely for mechanical orientation - both terminals are functionally identical. No polarity-sensitive routing is required, simplifying PCB layout and eliminating risk of incorrect placement in symmetric protection circuits like differential data lines.
What is the thermal resistance from junction to ambient for SMB8J10CAHE3_A/H?
The typical thermal resistance from junction to ambient (RθJA) for SMB8J10CAHE3_A/H is 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard JEDEC test conditions and informs derating calculations for sustained power dissipation or elevated ambient temperatures.
How does the 800 W peak pulse power rating of SMB8J10CAHE3_A/H compare to similar SMB-package TVS diodes?
SMB8J10CAHE3_A/H delivers 800 W peak pulse power (PPPM) - among the highest in the SMB footprint - exceeding standard SMBJ-series devices (e.g., SMBJ10CAHE3_A/H at 600 W). This higher rating enables robust protection against severe transients like ISO 7637-2 Pulse 5a without requiring larger packages or parallel devices.
