Product details
Overview
SMBJ6.0AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping inductive switching transients and ESD events on power rails and signal lines. 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), and clamps to ≤10.3 V at 58.3 A peak surge current - used in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the SMBJ6.0AHE3_B/I datasheet, SMBJ6.0AHE3_B/I pinout, SMBJ6.0AHE3_B/I application, or SMBJ6.0AHE3_B/I equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity with cathode band marking, low clamping ratio (VC/VBR ≈ 1.49), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<800 µA at VWM), while the 100 °C/W junction-to-ambient thermal resistance requires careful PCB copper pad design for sustained surge handling.
The SMBJ6.0AHE3_B/I is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and meets MSL Level 1 per J-STD-020 (peak reflow 260 °C). Its AEC-Q101 qualification confirms suitability for automotive under-hood and infotainment power rail protection where reliability across -55 °C to +150 °C is mandatory.

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. | Lacks automotive qualification; suitable for consumer/industrial use only. | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive compliance needs. |

FAQ
What is the maximum clamping voltage of SMBJ6.0AHE3_B/I at its rated peak pulse current?
The SMBJ6.0AHE3_B/I clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ6.0AHE3_B/I maintains this clamping performance across its full operating temperature range of -55 °C to +150 °C.
Is SMBJ6.0AHE3_B/I suitable for bidirectional transient protection?
No, SMBJ6.0AHE3_B/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., SMBJ6.0CA). Using SMBJ6.0AHE3_B/I in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit.
Does SMBJ6.0AHE3_B/I require derating at elevated ambient temperatures?
Yes, SMBJ6.0AHE3_B/I must be derated above 25 °C ambient per Figure 2 in the datasheet. Its peak pulse power capability decreases linearly with rising junction temperature, reaching ~50% of 600 W at 100 °C ambient when mounted on minimum recommended copper pads. Thermal design using 5.0 mm × 5.0 mm pads per terminal is essential to maintain specified surge ratings.
What does the "HE3_B/I" suffix indicate in SMBJ6.0AHE3_B/I?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification; "B" is the revision code; "I" specifies packaging in 13-inch tape-and-reel format with 3200 units per reel. This distinguishes it from "H" (7-inch reel, 750 units) and non-HE3 variants like "E3" (commercial grade only). All HE3 variants meet JESD201 Class 2 whisker resistance.
Can SMBJ6.0AHE3_B/I be used in place of SMAJ6.0AHE3 in an existing design?
No - SMBJ6.0AHE3_B/I uses the SMB (DO-214AA) package, while SMAJ6.0AHE3 uses the smaller SMA (DO-214AC) package. Though both share similar electrical specs, their footprints, thermal resistance (RθJA = 100 °C/W vs. 140 °C/W), and surge current handling differ. Direct substitution would require PCB layout changes and thermal validation due to the 25% larger SMB pad area and lower thermal impedance.
