Product details
Overview
SMBJ6.0AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), 58.3 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge current - deployed on IC power rails, MOSFET gate drivers, and sensor signal lines in industrial and automotive systems.
For engineers reviewing the SMBJ6.0AHE3_B/H datasheet, SMBJ6.0AHE3_B/H pinout, SMBJ6.0AHE3_B/H application, or SMBJ6.0AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 100 °C/W junction-to-ambient thermal resistance, low clamping voltage under surge, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with power or signal paths, triggering into avalanche conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the unidirectional configuration provides forward conduction capability up to 50 A (VF ≤ 3.5 V).
The device is rated for repetitive 10/1000 µs surge waveforms at 0.01 % duty cycle and derates linearly above 25 °C ambient per Fig. 2. It meets MSL Level 1 per J-STD-020, supports lead-free reflow up to 260 °C peak, and is qualified to AEC-Q101 for automotive-grade reliability.

IC Role / Device Role / Timing Role: TVS connected between sensor output and ground, absorbing ±8 kV contact ESD (IEC 61000-4-2) without latch-up or parameter shift. Use Value: Low 800 µA leakage at 6.0 V VWM avoids loading the sensor's high-impedance output stage; 10.3 V clamping preserves ADC input integrity. |
| DC-DC Converter Input Protection | MOSFET Gate Driver Transient Suppression |
|
Use Scenario: Safeguarding 5 V input of buck converter feeding FPGA core voltage in telecom base station power management. IC Role / Device Role / Timing Role: Placed upstream of input capacitor to clamp fast-rising transients from hot-swap events or relay bounce on backplane power feeds. Use Value: 600 W rating handles 500 A surge peaks typical in 48 V telecom systems; 100 °C/W RθJA allows thermal design with minimal copper area. |
Use Scenario: Preventing gate oxide damage in high-side N-channel MOSFETs driven by PWM controllers in motor drive inverters. IC Role / Device Role / Timing Role: Connected between gate and source terminals to clamp Miller-induced voltage spikes during switching transitions. Use Value: Fast <1 ns response ensures clamping occurs before gate threshold is exceeded; 10.3 V VC limits stress below 20 V absolute max rating of common gate drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Commercial-grade (non-AEC-Q101), same electrical specs and SMB package; RoHS-compliant but not automotive-qualified. | Limited to non-automotive industrial or consumer use where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive qualification requirements and long-term reliability under thermal cycling is less critical. |
| SMBJ6.0CAHE3_B/H | Bidirectional variant with symmetric breakdown (±6.67–7.37 V); same AEC-Q101 qualification and package. | Required for AC-coupled or dual-polarity signal lines (e.g., RS-485, CAN bus) where reverse polarity surges must also be suppressed. | Choose only if bidirectional clamping is needed; otherwise, unidirectional SMBJ6.0AHE3_B/H offers lower leakage and tighter VBR tolerance for DC rails. |
Compared with SMBJ6.0A-E3/52, SMBJ6.0AHE3_B/H adds AEC-Q101 qualification for automotive deployment, while SMBJ6.0CAHE3_B/H trades unidirectional efficiency for symmetrical surge handling - making SMBJ6.0AHE3_B/H optimal for cost-sensitive yet reliability-critical DC power rail protection.

FAQ
What is the clamping voltage of SMBJ6.0AHE3_B/H at its rated peak pulse current?
The SMBJ6.0AHE3_B/H clamps to a maximum of 10.3 V when subjected to its rated 58.3 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at the device terminals with specified mounting conditions (0.2" × 0.2" copper pads), and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events. The SMBJ6.0AHE3_B/H maintains this clamping performance across its full operating temperature range.
Is SMBJ6.0AHE3_B/H qualified for automotive applications?
Yes, SMBJ6.0AHE3_B/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in the SMBJ5.0A–SMBJ188A datasheet (Rev. 09-Jan-2024, p. 1). This qualification covers stress tests including temperature cycling, humidity bias, and high-temperature operating life - validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS sensor interfaces. The SMBJ6.0AHE3_B/H meets all required failure rate and parametric stability criteria.
What is the maximum reverse leakage current of SMBJ6.0AHE3_B/H at its stand-off voltage?
The SMBJ6.0AHE3_B/H exhibits a maximum reverse leakage current (ID) of 800 µA at its 6.0 V stand-off voltage (VWM), tested at 25 °C ambient per the Vishay datasheet (p. 2, Electrical Characteristics table). This low leakage ensures minimal power loss and avoids interference with high-impedance nodes such as sensor outputs or reference inputs. Leakage remains within specification across the full -55 °C to +150 °C operating junction temperature range.
How does the thermal resistance of SMBJ6.0AHE3_B/H affect PCB layout?
The SMBJ6.0AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads per terminal. To maintain safe junction temperatures during repetitive surge events or elevated ambient conditions, designers should allocate adequate copper area and consider thermal vias beneath the pads. Reducing RθJA improves surge endurance and long-term reliability - especially critical in automotive applications where SMBJ6.0AHE3_B/H may experience repeated transient exposure.
What packaging format is used for SMBJ6.0AHE3_B/H?
SMBJ6.0AHE3_B/H is supplied in 7" diameter plastic tape and reel packaging, with a base quantity of 750 units per reel (ordering code suffix "_B/H").
