Product details
Overview
SMBJ10AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 10 V standoff voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform), commonly deployed for I/O protection in industrial sensor interfaces and automotive body control modules.
For engineers reviewing the SMBJ10AHE3_B/I datasheet, SMBJ10AHE3_B/I pinout, SMBJ10AHE3_B/I application, or SMBJ10AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with UL 497B for telecom/signal line protectors.
Technical Context
This TVS diode operates as a voltage-clamping device in reverse-biased configuration, conducting only when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5.0 μA at VWM), while the low incremental surge resistance enables effective energy diversion during 10/1000 μs surges.
The SMBJ10AHE3_B/I is rated for -55 °C to +150 °C operating junction temperature and meets J-STD-020 MSL Level 1 (260 °C peak reflow). Its cathode-band marking identifies polarity, and it supports automated SMT placement per JEDEC-compliant matte tin plating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V at IT = 1 mA - Confirmed breakdown range defining turn-on threshold under standardized test conditions |
| VC @ IPPM | 17.0 V at 35.3 A - Clamped voltage during 600 W 10/1000 μs surge, directly limiting downstream IC stress |
| PPPM | 600 W - Peak pulse power handling capability with industry-standard 10/1000 μs waveform |
| ID @ VWM | ≤5.0 μA - Reverse leakage current at rated standoff voltage, critical for low-power sensor rail integrity |
| TJ max | +150 °C - Maximum junction temperature enabling use in under-hood automotive environments |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads, guiding PCB thermal layout |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, single-ended unidirectional configuration with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H), compliant with IPC-7351B footprint standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; defines conduction path during positive transients on cathode side |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 12 V supply or CAN_H); conducts surge current to anode when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including BCM, infotainment power rails, and sensor interfaces requiring reliability under thermal cycling and vibration |
| 600 W peak pulse power (10/1000 μs) | Handles IEC 61000-4-5 Level 4 (4 kV) surges without degradation when mounted per recommended pad layout |
| Low clamping voltage (17.0 V) | Protects 12 V-rated ICs (e.g., LIN transceivers, microcontrollers) by limiting transient overvoltage below damage thresholds |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without moisture-induced popcorn failure or delamination |
| Glass passivated junction | Ensures long-term VBR stability and low leakage drift across 15-year automotive service life |
Applications

|---|---|
|
Use Scenario: Protecting 12 V power input and LIN bus lines against load dump and inductive switching transients in door module ECUs. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between LIN transceiver VCC pin and chassis ground. Use Value: Limits transient voltage to ≤17.0 V, preventing latch-up or gate oxide rupture in LIN PHY ICs during ISO 7637-2 Pulse 5a events. |
Use Scenario: Shielding RS-485 transceiver data lines (A/B) from ESD and field-induced surges in factory-floor temperature sensors. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional pair (SMBJ10AHE3_B/I + SMBJ10CAHE3_B/I) used on differential pair with common-mode choke. Use Value: Clamps common-mode surges to <17.0 V while maintaining signal integrity up to 10 Mbps due to low junction capacitance (~100 pF at 0 V). |
| Telecom Power Supply Input | Consumer Appliance Motor Driver |
|
Use Scenario: Safeguarding AC-DC adapter secondary-side 12 V output against lightning-induced surges entering via Ethernet or PoE lines. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC output rail upstream of DC-DC converter input. Use Value: Absorbs 600 W surge energy within 1000 μs, preventing overvoltage shutdown or MOSFET avalanche failure in downstream regulators. |
Use Scenario: Suppressing back-EMF spikes from brushed DC motors in smart washing machine control boards. IC Role / Device Role / Timing Role: Mounted across motor terminals with cathode tied to high-side switch (e.g., N-channel MOSFET drain). Use Value: Diverts 35.3 A peak current away from driver IC, reducing voltage overshoot to ≤17.0 V and extending MOSFET lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10AHM3_B/I | Halogen-free, RoHS-compliant variant with identical electrical specs and AEC-Q101 qualification | No functional difference; selected where halogen-free material compliance is mandated (e.g., EU medical equipment) | Direct substitution if halogen-free bill-of-materials required; same thermal and clamping performance |
| SMBJ10A-E3/5B | Commercial-grade (non-AEC-Q101), same SMB package, identical VWM/VBR/VC/PPPM, but rated for TJ = -55 °C to +150 °C without automotive qualification testing | Approved for industrial/commercial use only; not validated for automotive thermal cycling or humidity exposure | Cost-optimized alternative for non-automotive applications where AEC-Q101 is not required |
Compared with SMBJ10AHE3_B/I, the HM3 variant adds halogen-free compliance without altering clamping behavior, while the E3/5B version removes automotive qualification-making it suitable for cost-sensitive industrial designs where AEC-Q101 is unnecessary.

FAQ
What is the maximum clamping voltage of SMBJ10AHE3_B/I under a 10/1000 μs surge?
The SMBJ10AHE3_B/I has a maximum clamping voltage (VC) of 17.0 V at 35.3 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components see no more than 17.0 V during a 600 W transient event, provided the device is mounted on the recommended 0.2" × 0.2" copper pads.
Is SMBJ10AHE3_B/I qualified for automotive applications?
Yes, SMBJ10AHE3_B/I is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 09-Jan-2024 (Document Number: 88392). This qualification covers stress tests including temperature cycling, humidity bias HAST, and mechanical shock, making SMBJ10AHE3_B/I suitable for under-hood and cabin automotive modules such as body control units and sensor interfaces.
What does the "HE3" suffix indicate in SMBJ10AHE3_B/I?
The "HE3" suffix in SMBJ10AHE3_B/I denotes a RoHS-compliant, AEC-Q101-qualified version with matte tin-plated leads meeting J-STD-002 solderability and JESD 22-B102 whisker resistance Class 2. The "B/I" indicates tape-and-reel packaging: "B" is the revision code, and "I" specifies 3200-unit reels on 13-inch diameter carriers.
Can SMBJ10AHE3_B/I be used for bidirectional transient protection?
No, SMBJ10AHE3_B/I is strictly unidirectional. For bidirectional protection, Vishay specifies the CA-suffix variant (e.g., SMBJ10CAHE3_B/I). Using SMBJ10AHE3_B/I on AC-coupled or symmetrical signal lines risks forward conduction during negative transients, potentially damaging the device or failing to suppress.
What is the thermal resistance junction-to-ambient (RθJA) for SMBJ10AHE3_B/I?
The SMBJ10AHE3_B/I has a typical RθJA of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This value guides PCB layout decisions-larger copper areas or internal planes can reduce effective RθJA and improve sustained surge handling.
