Product details
Overview
TPIC5223LD from Texas Instruments is a dual-channel, electrically isolated N-channel enhancement-mode power DMOS array with integrated gate protection zeners and logic-level drive capability. It delivers 60 V drain-source breakdown, 0.38 Ω typical rDS(on) at VGS = 5 V, and 3 A pulsed current per channel, enabling robust switching in industrial relay drivers and solenoid control circuits.
For engineers reviewing the TPIC5223LD datasheet, TPIC5223LD pinout, TPIC5223LD application, or TPIC5223LD equivalent, key selection criteria include its gate-protected architecture, –40°C to 125°C case temperature range, 4000 V HBM ESD rating, and SOIC-8 surface-mount package compatibility with logic-level microcontroller outputs.
Technical Context
The TPIC5223LD integrates two independent DMOS transistors with on-chip ZCXa/ZCXb zener diodes per channel for gate overvoltage clamping up to 18 V and ESD protection. Each channel operates with separate drain, source, and gate terminals, ensuring electrical isolation between outputs.
It features low-threshold operation (VGS(th) = 1.5–2.2 V), supports direct interface to 3.3 V/5 V logic, and includes internal source/drain diodes with 210 ns reverse recovery time (D1/D2) and 50 ns (Z1/Z2). Thermal design is enabled by RθJA = 130°C/W and RθJB = 78.6°C/W on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 60 V - Supports load switching up to 48 V DC without avalanche stress under normal operation. |
| rDS(on) | 0.38 Ω typ at VGS = 5 V, TC = 25°C - Enables <1 V conduction loss at 1 A, minimizing heat generation in compact layouts. |
| Pulsed Current | 3 A per channel (10 ms, 2% duty) - Handles short-duration inductive kickback from relays and solenoids. |
| ESD Rating | 4000 V HBM - Integrated zener protection eliminates need for external TVS diodes on gate inputs. |
| Operating Temperature | –40°C to 125°C case range - Qualified for under-hood automotive and industrial control environments. |
| Gate Threshold | 1.5–2.2 V - Ensures reliable turn-on with standard 3.3 V GPIO, reducing risk of partial enhancement. |
| Thermal Resistance | RθJA = 130°C/W - Requires minimal copper area for thermal management in SOIC-8 footprint. |
Pinout & Package
TPIC5223LD is housed in an 8-pin SOIC (D package), surface-mount outline with exposed pad not present. Pin 5 is NC (no internal connection); all other pins are electrically active and functionally assigned as shown below.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Common reference for both channels; must be lowest potential node in system (no terminal may go below GND). |
| 2 | SOURCE1 | Source terminal of Channel 1; connects to load return path or ground-side switching configuration. |
| 3 | GATE2 | Logic-level input for Channel 2; accepts 0–5 V signals with ±50 mA zener-limited gate current. |
| 4 | DRAIN2 | High-side output of Channel 2; rated for 60 V, 3 A pulsed, with integrated body diode (D2). |
| 5 | NC | No internal connection - left unconnected per datasheet; no routing or stitching required. |
| 6 | DRAIN1 | High-side output of Channel 1; electrically isolated from Channel 2, with dedicated D1 body diode. |
| 7 | GATE1 | Logic-level input for Channel 1; independently protected by ZC1a/ZC1b zeners up to 18 V. |
| 8 | SOURCE2 | Source terminal of Channel 2; enables dual low-side or high-side configurations depending on layout. |
Key Features
| Feature | Design Value |
|---|---|
| Independent Gate Protection | Per-channel ZCXa/ZCXb zeners clamp VGS to ≤18 V and provide 4000 V HBM ESD immunity without external components. |
| Logic-Level Compatibility | Turns on fully at VGS = 4.5–5 V, eliminating need for level-shifting circuitry when driven by MCU GPIOs. |
| Electrically Isolated Channels | Zero shared conduction path between Channel 1 and Channel 2 - supports dual independent loads with different ground domains. |
| Integrated Body Diodes | D1/D2 (210 ns trr) and Z1/Z2 (50 ns trr) enable freewheeling and fast clamping for inductive loads. |
| High-Temperature Operation | Rated for continuous operation at TC = 125°C - suitable for sealed enclosures and engine bay applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel logic-level power DMOS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPIC2603D | Single-channel, identical SOIC-8 package and gate protection, but lacks second output; rDS(on) = 0.45 Ω. | Requires two devices for dual-load control; higher conduction loss per channel. | Choose when only one high-current switch is needed and board space allows duplication. |
| ULN2803ADWR | 8-channel Darlington array, 500 mA per channel, no integrated gate protection, VCE(sat) ≈ 1.3 V. | Lower peak current (0.5 A vs. 3 A), higher saturation voltage, no ESD zeners - needs external protection. | Prefer for low-speed, low-power logic buffering where cost-per-channel is prioritized over surge handling. |
Compared with TPIC5223LD, TPIC2603D offers identical protection and thermal specs but halves channel count, while ULN2803ADWR trades surge capability and integrated protection for higher channel density and lower cost in non-critical 500 mA applications.

FAQ
What is the maximum safe gate-to-source voltage for TPIC5223LD?
The TPIC5223LD specifies a gate-to-source voltage range of –9 V to +18 V under absolute maximum ratings. Operation beyond ±18 V risks permanent damage to the integrated ZCXa/ZCXb zener clamps. For reliable long-term use, keep VGS within 0–5 V during normal switching, as the device is optimized for logic-level drive. The 18 V upper limit reflects the zener breakdown threshold, not recommended operating voltage.
Can TPIC5223LD drive inductive loads without external flyback diodes?
Yes, TPIC5223LD can drive inductive loads without external flyback diodes due to its integrated D1/D2 source-drain body diodes and Z1/Z2 gate-protection zeners. D1/D2 provide freewheeling paths with 210 ns reverse recovery time, sufficient for typical relay and solenoid switching frequencies. However, for high-di/dt or high-energy inductive loads, external snubbers may still be advised to manage voltage overshoot beyond the 100 V drain-to-GND rating.
Is TPIC5223LD pin-compatible with newer TI alternatives like TPIC2603D?
No, TPIC5223LD is not pin-compatible with TPIC2603D. While both use the SOIC-8 (D) package, TPIC5223LD has eight functional pins including GND, two independent SOURCE/GATE/DRAIN sets, and one NC pin (Pin 5), whereas TPIC2603D repurposes several pins for single-channel operation and different internal routing. Direct substitution would require PCB redesign and signal reassignment.
What is the thermal performance of TPIC5223LD on a standard FR4 PCB?
On a standard FR4 PCB with no heatsink, TPIC5223LD exhibits a junction-to-ambient thermal resistance (RθJA) of 130°C/W. At 1 A continuous drain current and 0.38 Ω rDS(on), power dissipation is ~0.38 W, resulting in ~50°C junction-to-ambient rise above ambient. This allows full-rated operation up to ~75°C ambient temperature before reaching the 150°C max junction limit, assuming proper copper pour and airflow.
Does TPIC5223LD support high-side or low-side switching configurations?
TPIC5223LD supports both high-side and low-side switching via flexible pin assignment: DRAIN1/DRAIN2 serve as high-side outputs, while SOURCE1/SOURCE2 serve as low-side returns. When used in high-side mode, the load connects between VCC and DRAINx, with SOURCEx tied to GND; in low-side mode, the load connects between VCC and SOURCEx, with DRAINx grounded. GND (Pin 1) must remain the system reference - no terminal may go below it.
