Product details
Overview
TPIC5403DW from Texas Instruments is a monolithic gate-protected 4-channel N-channel enhancement-mode DMOS array with integrated zener diodes for ESD protection, 60 V drain-to-source breakdown voltage, 0.23 Ω typical rDS(on), and −40°C to 125°C case temperature operation - used in industrial relay drivers and solenoid control circuits.
For engineers reviewing the TPIC5403DW datasheet, TPIC5403DW pinout, TPIC5403DW application, or TPIC5403DW equivalent, key selection considerations include pulsed current capability (11.25 A per channel), fast commutation speed (trr ≤ 160 ns), high-voltage output tolerance (60 V), and integrated gate protection zeners rated for 4000 V HBM ESD.
Technical Context
The TPIC5403DW integrates four electrically isolated DMOS transistors in a single SOIC-24 package, each featuring dual integrated zener diodes (ZCXa/ZCXb) across gate–source to clamp overvoltage and prevent gate oxide damage. Its architecture supports independent channel switching without shared substrate coupling.
Each channel delivers 2.25 A continuous drain current at TC = 25°C with low on-resistance (0.23 Ω typ), fast turn-on/turn-off delay times (td(on) = 32–55 ns, td(off) = 27–50 ns), and reverse-recovery time of 160 ns for the body diodes (D1–D4), enabling reliable operation in inductive load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 60 V - supports driving inductive loads up to 48 V nominal bus systems with margin against transients. |
| rDS(on) | 0.23 Ω typ at VGS = 10 V, TC = 25°C - enables low conduction loss and <1.5 W total dissipation at full continuous load per channel. |
| Pulsed Current | 11.25 A per channel (10 ms pulse, 2% duty) - handles surge currents from relay coils and solenoids during energization. |
| ESD Protection | 4000 V HBM - eliminates need for external gate protection components in standard industrial environments. |
| Operating Temperature | −40°C to 125°C case temperature - qualified for under-hood automotive and factory-floor industrial applications. |
| Reverse Recovery Time | 160 ns (D1–D4) - limits switching losses and voltage overshoot when interrupting inductive current. |
| Thermal Resistance | RθJA = 90°C/W - requires minimal PCB copper area for thermal management in non-heatsinked layouts. |
Pinout & Package
TPIC5403DW uses a 24-pin wide-body SOIC (DW) surface-mount package with exposed thermal pad (not electrically connected). Pin assignments are validated per TI SLIS038A datasheet Figure "DW PACKAGE (TOP VIEW)" and schematic diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | DRAIN1 | Power output terminal for Channel 1; connects to load anode or inductive load return path. |
| 3 | GATE1 | CMOS-compatible logic-level input controlling Channel 1; accepts 0–10 V drive with ±50 mA zener clamping. |
| 5, 6 | SOURCE1 | Channel 1 source node; tied to GND in low-side switch configuration; provides Kelvin sense path for accurate current monitoring. |
| 10 | GND | Common reference for all four channels and internal zener clamps; must be low-impedance connection to minimize ground bounce. |
| 7, 8 | SOURCE2 | Channel 2 source node; electrically isolated from SOURCE1 but shares GND reference; supports independent load referencing. |
| 23, 24 | DRAIN4 | Power output for Channel 4; identical electrical behavior to DRAIN1–DRAIN3; supports parallel channel use for higher current. |
| 22 | GATE4 | Independent logic input for Channel 4; no cross-talk with other gates due to monolithic isolation structure. |
| 19, 20 | SOURCE3 | Channel 3 source node; pin-paired for low-inductance layout; matches SOURCE1/SOURCE2/SOURCE4 routing symmetry. |
| 13, 14 | DRAIN2 | Channel 2 power output; shares same voltage rating and pulse current capability as DRAIN1. |
| 15 | GATE2 | Channel 2 gate input; driven by same logic family as GATE1; compatible with 3.3 V or 5 V microcontroller outputs. |
| 17, 18 | SOURCE4 | Channel 4 source node; completes quad-channel low-side switching topology with dedicated Kelvin sensing capability. |
| 4, 9, 16, 21 | GND | Four dedicated ground pins - reduce common-impedance coupling and improve noise immunity in multi-channel switching. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Gate Zener Protection | ZCXa/ZCXb diodes per channel clamp VGS to ±9 V/18 V, eliminating external TVS devices and reducing BOM count. |
| Electrically Isolated Channels | Four independent DMOS transistors share no substrate coupling - prevents fault propagation and enables mixed-voltage load control. |
| High-Voltage Inductive Load Handling | 60 V VDS rating + 100 V drain-to-GND breakdown allows safe operation with 48 V systems and flyback spikes up to 80 V. |
| Fast Commutation Speed | 14–30 ns rise time and 7–15 ns fall time minimize switching losses and EMI generation in PWM-driven solenoid applications. |
| Kelvin Source Connections | Dual-source pins per channel enable precise current sensing without IR drop error - critical for closed-loop load monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel N-channel DMOS driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPIC2101DW | Lower VDS (40 V), lower pulsed current (6 A), no integrated zeners - requires external gate protection. | Restricted to 24 V systems only; unsuitable for 48 V industrial buses or high-spike inductive loads. | Select when cost sensitivity outweighs voltage margin and external protection is acceptable. |
| ULN2803ADW | Bipolar Darlington array (not MOSFET); higher VCE(sat) (1.3 V), slower switching (1 µs tr/tf), no ESD zeners. | Limited to low-frequency (<1 kHz) switching; higher power loss precludes high-duty-cycle solenoid use. | Choose only for legacy 5 V TTL-compatible designs where switching speed and efficiency are secondary. |
Compared with TPIC2101DW and ULN2803ADW, the TPIC5403DW delivers superior voltage headroom, integrated gate protection, and MOSFET-level efficiency - making it the only option among the three qualified for 48 V industrial control and fast-switching solenoid applications.

FAQ
What is the maximum continuous drain current per channel for the TPIC5403DW?
The TPIC5403DW supports 2.25 A continuous drain current per channel at case temperature TC = 25°C, derating to ~1.5 A at TC = 100°C per the thermal resistance curve in Figure 15. This rating assumes proper PCB copper area for heat dissipation and accounts for the device's 0.23 Ω typical rDS(on). The TPIC5403DW must not exceed its 1.39 W total power dissipation limit under continuous operation.
Does the TPIC5403DW require external gate resistors for safe operation?
No, the TPIC5403DW does not require external gate resistors for basic switching, as its internal gate resistance is 0.25 Ω and gate charge is only 6.6–8 nC. However, a small series resistor (10–47 Ω) is recommended to dampen ringing in high-dV/dt environments or when driving long PCB traces. The TPIC5403DW's integrated zener diodes provide inherent gate protection, eliminating the need for external TVS devices.
Can the TPIC5403DW be used in high-side switch configurations?
No, the TPIC5403DW is configured exclusively as a low-side switch. Its four N-channel DMOS transistors have source terminals referenced to GND, and the datasheet explicitly states "no terminal may be taken below GND" (Note A). High-side operation would require P-channel devices or floating gate drivers - neither supported by the TPIC5403DW's architecture or pinout.
What is the purpose of the dual zener diodes (ZCXa and ZCXb) per channel in the TPIC5403DW?
Each channel of the TPIC5403DW includes two integrated zener diodes (ZCXa and ZCXb) connected between gate and source to clamp both positive and negative gate–source voltage excursions. ZCXa protects against positive overvoltage (up to +18 V), while ZCXb clamps negative transients (down to −9 V), enabling 4000 V HBM ESD protection and preventing gate oxide rupture during inductive kickback or hot-plug events. This eliminates external protection components in the TPIC5403DW design.
Is the TPIC5403DW RoHS compliant and lead-free?
The TPIC5403DW packaging information indicates "TBD" for Eco Plan and "Call TI" for Lead/Ball Finish in the official TI documentation, meaning RoHS or Pb-Free status was not formally defined at time of obsolescence. No JEDEC MSL rating is published. For compliance-critical designs, users must verify material content through TI's archived product change notices or contact TI directly - the TPIC5403DW itself contains no explicit RoHS or Green labeling in its datasheet or packaging addendum.
