Texas Instruments TPIC5302D

Overview

TPIC5302D from Texas Instruments is a monolithic triple N-channel enhancement-mode DMOS power transistor array in a 16-pin SOIC (D) package, delivering 60 V drain-to-source breakdown voltage, 0.3 Ω typical r_DS(on) at 10 V_GS, and 7 A pulsed current per channel. It operates from −40°C to 125°C case temperature and integrates three electrically isolated high-voltage switches with built-in source-to-drain diodes for inductive load control in industrial motor drivers and solenoid interfaces.

For engineers reviewing the TPIC5302D datasheet, TPIC5302D pinout, TPIC5302D application, or TPIC5302D equivalent, this device is evaluated for high-side/low-side switching in 24–48 V DC systems requiring fast commutation, avalanche energy tolerance (10.5 mJ), and robust thermal performance on FR4 PCBs without heatsinks.

Technical Context

The TPIC5302D implements three independent DMOS transistors with common GND terminal and isolated source/drain terminals-each channel features intrinsic body diode (Z1–Z3) and reverse-biased GND-to-drain diodes (D1–D3). Gate drive requires 10 V for full conduction, with threshold voltage specified at 1.5–2.2 V at 1 mA ID.

Switching behavior is characterized by 23–46 ns turn-on delay, 25–50 ns turn-off delay, and sub-10 ns rise/fall times into 50 Ω loads. Thermal design relies on R_θJA = 115°C/W (FR4, no heatsink) and R_θJP = 32°C/W, enabling sustained 1.4 A continuous drain current per channel at T_C = 25°C.

FAQ

What is the maximum continuous drain current per channel for TPIC5302D at 125°C case temperature?

The TPIC5302D supports 1.4 A continuous drain current per channel at T_C = 25°C. At T_C = 125°C, derating applies: r_DS(on) increases to 0.41–0.5 Ω, and maximum continuous current drops to approximately 0.95 A per channel based on thermal limits and power dissipation (1087 mW total). Always verify junction temperature using R_θJA = 115°C/W and actual board layout.

Does TPIC5302D include internal protection diodes for inductive loads?

Yes, TPIC5302D integrates three intrinsic source-to-drain body diodes (Z1, Z2, Z3) and three reverse-biased GND-to-drain diodes (D1, D2, D3). The source-to-drain diodes provide freewheeling paths for inductive loads, with t_rr(SD) = 35 ns and Q_RR = 0.04 µC at 25°C. These eliminate the need for external flyback diodes in most solenoid and relay driving applications.

Can TPIC5302D be used in high-side switching configurations?

TPIC5302D is configured as a low-side switch: its sources connect to GND or load return, and drains drive the load high-side. To implement high-side switching, external level-shifting circuitry or gate drivers are required because the device lacks floating gate drive capability. Its GND-referenced architecture makes it optimal for grounded-load topologies like PLC output stages and motor brake circuits.

What is the avalanche energy rating of TPIC5302D and how is it tested?

The TPIC5302D is rated for 10.5 mJ single-pulse avalanche energy (E_AS) at T_C = 25°C, measured per Figure 4 in the datasheet using a controlled inductive test circuit with I_AS = 7 A, V_(BR)DSX ≥ 60 V, and defined avalanche time (t_av). This rating confirms ruggedness against unclamped inductive switching events, such as solenoid de-energization without external snubbers.

Is TPIC5302D still in active production and what is its RoHS status?

No - according to TI's official packaging addendum, TPIC5302D is marked "OBSOLETE" with no active production or Pb-Free conversion plan (TBD). It remains available through authorized distributors and Aetrix Electronics' legacy inventory, but new designs should consider alternatives like TPIC2603D or modern integrated drivers. RoHS compliance cannot be guaranteed as eco-plan data is unspecified.
