Product details
Overview
TBD62502AFG from Toshiba Electronic Devices & Storage Corporation is a 7-channel sink-type DMOS transistor array IC designed for high-voltage, medium-current switching in industrial control and relay driver applications. It delivers 50 V output voltage rating, 300 mA per channel maximum output current, and requires ≥14 V input to activate outputs - used to drive solenoids, LEDs, and small DC loads in PLC I/O modules and printer mechanisms.
For engineers reviewing the TBD62502AFG datasheet, TBD62502AFG pinout, TBD62502AFG application, or TBD62502AFG equivalent, key selection criteria include verified sink-current capability per channel, thermal derating behavior on SOP-16 PCB layouts, input logic threshold compatibility with 14 V TTL/CMOS drivers, and absence of internal overcurrent protection requiring external design safeguards.
Technical Context
This device integrates seven independent N-channel DMOS transistors in a single SOP16 package, each configured as a low-side switch with no internal flyback diodes or current limiting. Its operation relies on externally supplied load voltage up to 50 V and demands careful thermal management due to 0.625 W power dissipation limit at 25°C ambient on standard PCB layout.
The TBD62502AFG exhibits fixed-input-threshold logic: outputs turn ON only when input voltage exceeds 14 V (min), and turn OFF when input drops below 7.0 V (max), making it incompatible with 3.3 V or 5 V microcontroller direct drive without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Rating | 50 V max - supports driving inductive loads like 24 V/48 V solenoids and relays without external clamping if properly snubbed. |
| Output Current per Channel | 300 mA max - usable for LED arrays or small DC motors; derates to 120 mA at 85°C ambient with 50% duty cycle in SOP16 package. |
| Input Voltage (ON) | 14 V min - requires dedicated 14–25 V logic supply; not compatible with standard 5 V or 3.3 V GPIO without level translation. |
| Input Voltage (OFF) | 7.0 V max - ensures reliable turn-off when driven by open-collector or pull-down interfaces at ≤7 V. |
| On-Resistance (RDS(on)) | 0.4 V typ. @ 200 mA - yields ~2 W/channel power loss at full current; mandates heatsinking or current derating in multi-channel operation. |
| Turn-on/turn-off Delay | 0.4 μs / 0.8 μs - enables PWM switching up to ~500 kHz, but limited by output capacitance and load inductance. |
| Power Dissipation (SOP16) | 0.625 W @ 25°C - drops to zero at 145°C ambient; requires 5 mW/°C derating beyond 25°C on 30 mm × 30 mm PCB. |
Pinout & Package
SOP16-P-225-1.27 surface-mount package (1.27 mm pitch, 10.0 × 4.4 mm body size, 0.16 g typical weight) with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–7 (I1–I7) | Input control signal | Active-high logic inputs; each enables corresponding output sink when ≥14 V applied. |
| 8 | GND | Common source reference for all DMOS channels; must be low-impedance connection to minimize ground bounce. |
| 9 | NC | No internal connection; must remain unconnected and unstubbed to avoid parasitic coupling. |
| 10–16 (O7–O1) | Output drain terminals | Seven independent open-drain outputs; each sinks current from external load to GND when its input is high. |
Key Features
| Feature | Design Value |
|---|---|
| 7-channel integration | Reduces board space and component count vs. discrete MOSFETs; eliminates need for 7 separate gate resistors and level shifters. |
| 50 V output voltage rating | Enables direct interface with 24 V industrial bus systems without external voltage translation or Zener clamping. |
| 300 mA per channel | Supports driving multiple 20 mA LEDs in parallel or single 24 V/100 mA solenoid per channel without external current amplification. |
| High-threshold input logic | Immune to noise-induced false triggering in electrically noisy environments such as factory automation cabinets. |
| No internal protection circuits | Requires external flyback diodes across inductive loads and current-limiting resistors on inputs to prevent latch-up or avalanche failure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar sink-type transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TBD62502APG | DIP-16 through-hole package; higher 1.47 W power dissipation rating; 1.11 g weight; 2.54 mm pitch. | Better thermal performance in prototyping or low-volume industrial panels where manual soldering or socketing is preferred. | Select TBD62502APG when board-level rework, thermal margin above 1 W, or legacy DIP footprint compatibility is required. |
| ULN2803ADWR | 8-channel Darlington array; 500 mA per channel; built-in clamp diodes; 3–5 V logic compatible; SOIC-18 package. | Direct microcontroller interfacing without level shifters; suited for 5 V systems; lower voltage rating (50 V same, but lower safe operating area). | Choose ULN2803ADWR for 5 V MCU-driven designs needing integrated flyback protection and higher per-channel current, accepting larger footprint and Darlington saturation voltage penalty. |
Compared with TBD62502APG, the TBD62502AFG offers smaller PCB area and automated assembly compatibility but sacrifices thermal headroom; versus ULN2803ADWR, it provides tighter timing and lower on-resistance but requires external protection and 14 V logic - making it optimal for high-reliability 24 V industrial systems with dedicated level-shifted control.

FAQ
What is the minimum input voltage required to turn on an output channel of the TBD62502AFG?
The TBD62502AFG requires a minimum input voltage of 14 V at pins I1–I7 to reliably turn on any output channel. This threshold is specified under conditions of IOUT ≥ 100 mA and VOUT = 2 V. Applying less than 14 V may result in partial or unstable conduction, especially at elevated temperatures or higher load currents. The TBD62502AFG is not compatible with standard 3.3 V or 5 V logic without external level-shifting circuitry.
Does the TBD62502AFG include built-in flyback diodes for inductive load protection?
No, the TBD62502AFG does not include built-in flyback diodes or any internal protection circuits. When driving inductive loads such as relays or solenoids, external flyback diodes must be connected across each load with cathode to the positive supply rail and anode to the corresponding O1–O7 output pin. Failure to provide this protection risks avalanche breakdown and permanent damage to the TBD62502AFG during load turn-off.
What is the maximum continuous output current per channel for the TBD62502AFG at 85°C ambient temperature?
At 85°C ambient temperature and 50% duty cycle, the TBD62502AFG supports a maximum continuous output current of 120 mA per channel in its SOP16 package. This value is derived from thermal derating data: the package's 0.625 W power dissipation limit at 25°C reduces by 5 mW/°C, resulting in ~0.475 W available at 85°C, which - combined with typical RDS(on) of 0.4 V - yields ~120 mA (P = I²R → I = √(P/R)). Exceeding this current risks thermal runaway.
Can the TBD62502AFG be used with a 5 V microcontroller GPIO directly?
No, the TBD62502AFG cannot be driven directly by a 5 V microcontroller GPIO. Its input threshold requires ≥14 V to guarantee output turn-on, and it tolerates a maximum of 7.0 V for reliable turn-off. Connecting a 5 V signal will leave the device in an indeterminate state - neither fully on nor off - leading to excessive power dissipation and potential thermal failure. A dedicated level-shifter stage (e.g., bipolar transistor or MOSFET-based) is mandatory for 5 V MCU interfacing with the TBD62502AFG.
What is the function of Pin 9 (NC) on the TBD62502AFG?
Pin 9 on the TBD62502AFG is designated NC (No Connection) and has no internal electrical connection. It must remain unconnected - neither tied to GND, VCC, nor left floating with stub traces. Routing copper or placing vias near Pin 9 may introduce parasitic coupling or unintended capacitance that affects adjacent signal integrity, particularly for fast-switching inputs I1–I7 or outputs O1–O7. PCB layout guidelines require Pin 9 to be excluded from all metal layers.
