Product details
Overview
SDA006-7 from Diodes Incorporated is a 3-phase full-wave bridge rectifier and data bus transient suppressor in a single SOT-363 package, integrating six ultra-fast switching diodes with 75 V peak repetitive reverse voltage, 215 mA forward current per element, and 16 V clamping voltage at 14.5 A surge - used for industrial motor drive DC-link protection and 3-line RS-485/RS-422 bus rail clamping.
For engineers reviewing the SDA006-7 datasheet, SDA006-7 pinout, SDA006-7 application, or SDA006-7 equivalent, this device serves dual roles in AC-to-DC conversion and ESD/surge suppression across three differential signal pairs, with verified IEC 61000-4-2 (±10 kV air) and 61000-4-5 (14.5 A, 8×20 μs) compliance, low 4.0 ns reverse recovery time, and 11 pF I/O-to-ground capacitance critical for high-speed data integrity.
Technical Context
The SDA006-7 implements a monolithic 3-phase full-wave bridge configuration with internal interconnection of six diodes: three anodes tied to AC1/AC2/AC3 inputs and three cathodes joined at DC+, while GND serves as the common return node. Its dual-function topology supports simultaneous rectification and bidirectional transient clamping between each AC line and ground or VCC rail.
Designed for compact industrial and communication interfaces, it delivers 2.0 A non-repetitive surge capability with 16 V clamping under 14.5 A 8×20 μs waveform, and maintains ≤1.25 V forward drop at 150 mA per diode - enabling efficient low-voltage DC bus generation and robust ±8 kV contact ESD protection without external TVS arrays.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase transient suppression and rectification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMC30D75CA | Discrete dual TVS array (75 V bi-directional), no rectification function; higher 35 pF I/O-to-I/O capacitance. | Requires external bridge rectifier; suited only for pure data line protection, not combined AC-DC conversion. | Select when surge-only protection is needed and board space permits separate rectifier + TVS placement. |
| GBU4K | Through-hole 4A 400 V bridge rectifier; no integrated transient suppression; no ESD/surge ratings provided. | Supports higher current but lacks IEC compliance; requires external TVS for data line use. | Select for high-power AC-DC supplies where transient protection is handled separately via PCB layout or dedicated ICs. |
Compared with SMC30D75CA and GBU4K, the SDA006-7 uniquely integrates both functions in one ultra-small package - delivering verified 3-phase rectification, 14.5 A surge clamping, and <12 pF I/O-to-ground capacitance - making it irreplaceable in space-constrained, dual-role industrial interfaces.

FAQ
What is the maximum continuous current per diode in the SDA006-7?
The SDA006-7 is rated for 215 mA forward continuous current per diode at 25°C ambient on FR-4 PCB. Derating applies above 25°C per the 625°C/W thermal resistance curve - at 70°C ambient, usable current drops to approximately 135 mA per diode to maintain safe junction temperature.
Can the SDA006-7 be used for single-phase rectification?
Yes - the SDA006-7 can be configured for single-phase full-wave rectification by connecting AC1 and AC2 together as one AC input, AC3 as the other, and using DC+ and DC− as output terminals. However, its optimized layout and internal symmetry are intended for true 3-phase operation; single-phase use does not leverage its full design advantage.
Is the SDA006-7 pinout compatible with standard SOT-363 logic ICs?
No - the SDA006-7 uses a custom pin assignment specific to its 3-phase bridge + clamp topology. Pin 1 is AC1 (anode), Pin 4 is GND (common cathode reference), and Pin 6 is DC+ (shared cathode/anode node); this differs fundamentally from digital logic or amplifier SOT-363 footprints and requires dedicated layout.
Does the SDA006-7 require external decoupling capacitors for ESD protection?
No - the SDA006-7's internal structure inherently provides bidirectional clamping between each AC line and GND/DC+ rails. However, a 100 nF ceramic capacitor between VCC and GND near the device is recommended to stabilize the clamping reference during fast transients, as noted in Diodes' test setup (Note 5).
