Product details
Overview
SMBJ6.0CAHE3_B/H 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 6.4 V minimum breakdown voltage (VBR), 6.0 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak surge current - used in automotive sensor protection, industrial I/O interfaces, and telecom line surge suppression.
For engineers reviewing the SMBJ6.0CAHE3_B/H datasheet, SMBJ6.0CAHE3_B/H pinout, SMBJ6.0CAHE3_B/H application, or SMBJ6.0CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, 10.3 V clamping voltage at rated IPPM, thermal resistance (RθJA = 100 °C/W), 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 with symmetrical avalanche breakdown in both directions, enabling robust transient suppression without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low incremental surge resistance, and fast response time (<1 ns).
Rated for -55 °C to +150 °C operating junction temperature and qualified to AEC-Q101, SMBJ6.0CAHE3_B/H supports automotive-grade reliability under repetitive surge stress (0.01% duty cycle). It meets UL 497B recognition (QVGQ2) and J-STD-020 MSL Level 1 reflow profile (260 °C peak).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA-E3/52 | Commercial-grade (non-AEC-Q101), same electrical specs and SMB package | Lacks automotive qualification; suitable for consumer/industrial non-automotive use | Select when AEC-Q101 is not required and cost optimization is prioritized |
| SMCJ6.0CAHE3_A/H | Higher-power variant (1500 W PPPM), larger SMC (DO-214AB) package, identical VBR/VWM | Used where higher surge energy handling is needed but PCB space allows larger footprint | Choose when system-level surge testing exceeds 600 W or longer pulse durations apply |
Compared with SMBJ6.0CAHE3_B/H, the E3/52 alternative offers identical clamping performance at lower qualification cost, while the SMCJ6.0CAHE3_A/H provides 2.5× higher pulse power in a physically larger package - enabling design flexibility across automotive, industrial, and telecom surge classes.

FAQ
What does the "CA" suffix indicate in SMBJ6.0CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration: SMBJ6.0CAHE3_B/H conducts symmetrically in both polarities, making it suitable for AC-coupled or differential signal lines where polarity is undefined. Unlike unidirectional "A" variants, it has no cathode band marking and exhibits matched VBR in forward and reverse directions - confirmed by its 6.4 V to 7.07 V breakdown range at 10 mA in both directions per Vishay Document 88392.
Is SMBJ6.0CAHE3_B/H compatible with lead-free reflow processes?
Yes, SMBJ6.0CAHE3_B/H is fully compatible with lead-free reflow. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and it is rated for MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C - verified in Vishay's packaging specifications and thermal characterization data.
How does the clamping voltage of SMBJ6.0CAHE3_B/H compare to its stand-off voltage?
SMBJ6.0CAHE3_B/H clamps to ≤10.3 V at its rated 58.3 A peak pulse current (10/1000 µs), while its maximum stand-off voltage is 6.0 V. This yields a clamping ratio (VC/VWM) of approximately 1.72, indicating effective overvoltage limiting with sufficient margin above normal operating voltage to avoid false triggering during ripple or noise.
Can SMBJ6.0CAHE3_B/H be used in place of a unidirectional TVS like SMBJ6.0AHE3_B/H?
No - SMBJ6.0CAHE3_B/H is not a drop-in replacement for unidirectional SMBJ6.0AHE3_B/H. While both share identical VWM (6.0 V) and package, the CA version lacks polarity marking and conducts in both directions, which may cause unintended conduction in DC-biased circuits. Use only where bidirectional protection is explicitly required and circuit topology supports symmetrical clamping.
What is the maximum reverse leakage current for SMBJ6.0CAHE3_B/H at its rated VWM?
At VWM = 6.0 V and TA = 25 °C, SMBJ6.0CAHE3_B/H exhibits a maximum reverse leakage current (ID) of 800 µA - specified in Vishay Document 88392 under ELECTRICAL CHARACTERISTICS for the SMBJ6.0CA variant. This value remains stable across its full operating temperature range due to glass-passivated junction construction.
