Product details
Overview
SMBJ10CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 µs waveform - deployed in industrial sensor interfaces and telecom line protection.
For engineers reviewing the SMBJ10CAHE3/5B datasheet, SMBJ10CAHE3/5B pinout, SMBJ10CAHE3/5B application, or SMBJ10CAHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and bidirectional clamping behavior critical for ESD/surge co-design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) of 11.1–12.3 V at 1.0 mA test current and reverse leakage current ≤5.0 µA at VWM. Its low clamping ratio (VC/VWM ≈ 1.7) ensures effective overvoltage suppression without excessive voltage overshoot during transient events.
Designed for automated SMT assembly, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), has matte tin-plated leads compliant with JESD 22-B102, and exhibits low incremental surge resistance for stable clamping under repetitive surges at 0.01% duty cycle.
Key Specifications

|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 11.1 V / 12.3 V at IT = 1.0 mA - Ensures reliable breakdown onset within tight tolerance band |
| VC @ IPPM | 17.0 V at 35.3 A - Clamped voltage during 10/1000 µs surge; defines protected circuit's max stress level |
| PPPM | 600 W - Peak transient energy handling capacity under standardized surge waveform |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads |
| TJ range | –55 °C to +150 °C - Full operational junction temperature range for harsh-environment deployment |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability per stress-test requirements |

Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
|
Use Scenario: Protecting analog output lines of pressure/temperature sensors exposed to load dump and inductive switching noise in factory automation systems. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt transients before reaching ADC input or signal conditioner. Use Value: Prevents sensor signal corruption and ADC saturation by limiting transient voltage to 17.0 V while maintaining 10 V system operating margin. |
Use Scenario: Safeguarding LIN bus communication lines in door modules against battery reverse connection and jump-start surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on LIN data line, leveraging bidirectional symmetry to absorb ±100 V transients without polarity alignment. Use Value: Enables robust LIN communication integrity under ISO 7637-2 Pulse 1/2a/5a stress profiles due to sub-20 V clamping and AEC-Q101 validation. |
| Telecom Line Interface | Consumer USB Port Protection |
|
Use Scenario: Shielding Ethernet PHY differential pairs (e.g., 10/100BASE-TX) from lightning-induced surges in outdoor access points. IC Role / Device Role / Timing Role: Paired SMBJ10CAHE3/5B devices on each line (TX+/TX−, RX+/RX−) to provide balanced, low-capacitance transient suppression. Use Value: Maintains signal integrity with <10 pF junction capacitance at zero bias while clamping common-mode surges to safe levels. |
Use Scenario: Guarding USB 2.0 D+/D− lines in portable speakers against ESD events per IEC 61000-4-2 ±15 kV contact discharge. IC Role / Device Role / Timing Role: Fast-response TVS placed adjacent to USB connector to divert ESD current away from USB transceiver IC. Use Value: Achieves <1 ns response time and 17.0 V clamping to prevent latch-up or gate oxide damage in downstream USB PHY. |
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 | No AEC-Q101 qualification; commercial-grade only; same electrical specs and SMB package | Suitable for non-automotive industrial or consumer use where automotive reliability testing is not required | Select when cost sensitivity outweighs need for automotive qualification and lifecycle assurance |
| SAC10CA | Same VWM (10 V) and VC (17 V), but lower PPPM (400 W); SOD-123FL package (smaller, lower thermal mass) | Limited to lower-energy transients; not recommended for IEC 61000-4-5 or load-dump scenarios | Choose only for space-constrained, low-surge environments like handheld device I/O where 600 W headroom is unnecessary |
Compared with SMBJ10CAHE3/5B, the SMBJ10CA-E3/5B offers identical surge performance without automotive qualification, while SAC10CA trades 33% peak power capability for 40% smaller footprint - making SMBJ10CAHE3/5B the optimal choice for AEC-Q101–mandated or high-energy transient environments.

FAQ
What is the clamping voltage of SMBJ10CAHE3/5B at its rated peak pulse current?
The SMBJ10CAHE3/5B has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A under the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuits during worst-case surge events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings. The SMBJ10CAHE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBJ10CAHE3/5B suitable for automotive applications?
Yes, SMBJ10CAHE3/5B is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, humidity bias, and high-temperature operating life - specifically validated for automotive subsystems such as body control modules, infotainment interfaces, and sensor nodes. Its –55 °C to +150 °C junction temperature range and MSL Level 1 reflow compatibility further support under-hood and cabin deployment. The SMBJ10CAHE3/5B is explicitly designated for automotive use via the "HE3" suffix.
How does the bidirectional design of SMBJ10CAHE3/5B affect its placement on PCBs?
The SMBJ10CAHE3/5B has no polarity marking and functions identically in both directions, eliminating orientation constraints during automated placement - unlike unidirectional TVS diodes that require cathode alignment. This simplifies layout for AC-coupled lines (e.g., RS-485, CAN, LIN) and floating references, reduces assembly errors, and enables direct replacement in legacy bidirectional designs. The SMBJ10CAHE3/5B's symmetric VBR (11.1–12.3 V) and VC ensure consistent clamping regardless of transient polarity.
What is the thermal resistance of SMBJ10CAHE3/5B, and how does it impact power derating?
The SMBJ10CAHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. This value directly governs power derating above 25 °C ambient: for example, at 85 °C ambient, its 5.0 W steady-state power dissipation drops to ~2.0 W. Engineers must apply this derating curve (Fig. 2 in datasheet 88392) when estimating sustained surge repetition rates or ambient thermal conditions - a key consideration for SMBJ10CAHE3/5B in enclosed industrial enclosures.
Does SMBJ10CAHE3/5B meet RoHS and halogen-free requirements?
Yes, SMBJ10CAHE3/5B is RoHS-compliant and halogen-free, as indicated by the "HE3" suffix per Vishay's ordering nomenclature. It uses molding compound meeting UL 94 V-0 flammability rating and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The "HE3" variant satisfies both environmental compliance and AEC-Q101 qualification - distinguishing it from "E3" (RoHS only) and "HM3" (halogen-free + RoHS, no AEC-Q101) variants. This makes SMBJ10CAHE3/5B suitable for green electronics programs in EU, China, and North America.
