Diodes Incorporated DLPA006-7

Overview

DLPA006-7 from Diodes Incorporated is a 3-phase full-wave bridge rectifier and data bus transient suppressor in SOT-363 package, integrating six ultra-fast switching diodes with ±15 kV IEC 61000-4-2 contact ESD protection per line, 85 V peak reverse voltage, and 160 mA forward current rating. It serves as rail clamp for three-dataline interfaces (DL1–DL3 to GND) and AC-to-DC conversion in compact industrial sensor nodes.

For engineers reviewing the DLPA006-7 datasheet, DLPA006-7 pinout, DLPA006-7 application, or DLPA006-7 equivalent, key selection factors include per-line capacitance (CLG = 2.5–3.5 pF), low trr = 3.0 μs, thermal resistance (RθJA = 417 °C/W on alumina), and RoHS-compliant matte tin terminations on alloy 42 leadframe.

Technical Context

The DLPA006-7 integrates six monolithic diodes in a single SOT-363 package configured as three independent bidirectional clamping pairs (DL1–GND, DL2–GND, DL3–GND) and simultaneously as a 3-phase full-wave bridge (AC1/AC2/AC3 inputs → DC+/DC− outputs). Its internal topology supports dual-mode operation without external reconfiguration.

All diodes share common thermal mass and exhibit matched VF (max 1.25 V at 150 mA) and IR (≤80 nA at 75 V, TJ = 150°C), enabling balanced clamping and rectification performance across temperature and signal polarity. The device meets IEC 61000-4-2 Level 4 ESD immunity with no external TVS required.

FAQ

What is the maximum recommended operating temperature for DLPA006-7 in a 3-phase rectifier configuration?

The DLPA006-7 has an operating temperature range of −65°C to +150°C. When used in 3-phase rectifier mode with continuous 100 mA load, junction temperature must remain ≤150°C. On alumina PCB (RθJA = 417 °C/W), ambient must stay ≤75°C to maintain safe thermal margin under 300 mW dissipation.

Can DLPA006-7 be used for CAN FD bus protection?

Yes - its CLG of 2.5–3.5 pF and trr of 3.0 μs preserve signal integrity up to 5 Mbps, meeting CAN FD physical layer requirements. The ±15 kV IEC 61000-4-2 contact rating exceeds ISO 11898-2 immunity targets, and VRRM = 85 V accommodates CAN common-mode transients.

Is pin 5 (NC) required to be grounded or left floating in layout?

Pin 5 is a true no-connect terminal with no internal bond wire. Diodes Incorporated's AP02001 pad layout specifies it as floating. Grounding it may introduce unintended parasitic capacitance or leakage; leaving it unconnected per datasheet avoids risk of signal coupling or thermal imbalance.

How does DLPA006-7 achieve dual functionality without external switches or configuration pins?

The internal die integrates six diodes in fixed topology: pins 1/3/4 serve as anodes for DL1/DL2/DL3 (or AC1/AC2/AC3), pin 2 is common cathode (GND/DC−), and pin 6 is dedicated cathode bank (DC+). This passive arrangement inherently supports both clamping (DLx→GND) and bridge rectification (ACx→DC+/DC−) simultaneously - no control logic or reconfiguration needed.
