Product details
Overview
TBD62304AFNG,EL from Toshiba Electronic Devices & Storage Corporation is a 7-channel low-active sink-type DMOS transistor array in SSOP-16 package, rated for 50 V output voltage and 500 mA per channel, designed for driving relays, LEDs, and solenoids in industrial control and automation systems.
For engineers reviewing the TBD62304AFNG,EL datasheet, TBD62304AFNG,EL pinout, TBD62304AFNG,EL application, or TBD62304AFNG,EL equivalent, key selection factors include its 0.65 mm pitch SSOP package thermal derating (6.24 mW/°C), 0.525 V typical ON-state voltage at 350 mA, and absence of built-in overcurrent or overvoltage protection circuits requiring external fuse integration.
Technical Context
The TBD62304AFNG,EL integrates seven independent N-channel DMOS sink drivers with common VCC and GND rails. Each channel operates with input logic referenced to VCC, enabling direct interface with microcontroller GPIOs without level-shifting.
It supports input voltage ranges from −20 V to VCC−3.5 V for active-low turn-on and VCC−0.4 V to VCC for turn-off, ensuring robust noise immunity and compatibility with TTL and CMOS logic families across 4.5–5.5 V supply operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Rating | 50 V max - supports driving inductive loads such as 24 V DC relays and solenoids without external clamping diodes |
| Per-Channel Output Current | 400 mA continuous (1 circuit ON, Ta = 25°C) - defines maximum steady-state load per driver under standard PCB thermal conditions |
| ON-State Voltage | 0.525 V typ. at 350 mA - determines power dissipation (≈184 mW/ch) and junction temperature rise during sustained conduction |
| Input Logic Threshold | VIN(ON): −20 V to VCC−3.5 V - enables direct connection to open-collector or negative logic sources |
| Thermal Derating | 6.24 mW/°C above 25°C (SSOP on 50×50 mm PCB) - requires thermal design margining when ambient exceeds 50°C |
| Turn-On/Off Delay | 0.6 μs typ. - suitable for PWM-driven LED dimming up to ~1 MHz with minimal timing skew across channels |
Pinout & Package
Package: SSOP16-P-225-0.65B - 16-pin shrink small-outline package with 0.65 mm lead pitch, 5.3 mm × 6.2 mm body size, and 0.07 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–7 (I1–I7) | Input control terminals | Active-low logic inputs; sinking current when pulled ≤ VCC−3.5 V to enable corresponding output |
| 8 | GND | Common ground reference for all internal DMOS sources and input logic |
| 9 | VCC | Positive supply rail (4.5–5.5 V); powers internal logic and sets output high-voltage reference |
| 10–16 (O7–O1) | Output drain terminals | Open-drain NMOS outputs; each sinks up to 400 mA to GND when corresponding input is active |
Key Features
| Feature | Design Value |
|---|---|
| 7-channel integrated sink driver | Reduces board space and BOM count vs. discrete MOSFET + resistor solutions for multi-load control |
| 50 V output voltage rating | Enables direct interface with 24 V industrial control buses without external voltage translation |
| Low ON-resistance (1.5 Ω typ.) | Minimizes conduction loss and self-heating during sustained 350 mA operation |
| No internal protection circuits | Requires external fuse and flyback diodes for inductive loads-designer retains full control over protection thresholds |

Equivalent & Alternatives
The following parts are listed as comparable options for similar sink-driver array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TBD62783AFNG,EL | 8-channel, same SSOP-16 package, 50 V/500 mA rating, but includes built-in clamp diodes | Reduces external component count for inductive loads; higher channel count increases routing density | Select when flyback protection integration is prioritized over cost and thermal budget |
| ULN2803ADWR | 8-channel, SOIC-18 package, 50 V/500 mA, integrated clamp diodes, TTL-compatible inputs | Larger footprint and different pinout; requires no external pull-up for TTL logic but lacks negative input capability | Select for legacy TTL system compatibility where board space permits SOIC-18 |
Compared with TBD62783AFNG,EL and ULN2803ADWR, the TBD62304AFNG,EL offers 7-channel flexibility in a compact SSOP-16 with negative-input capability, but requires external protection components-making it optimal for space-constrained designs where protection topology is already defined.

FAQ
What is the maximum continuous output current per channel for TBD62304AFNG,EL?
The TBD62304AFNG,EL supports 400 mA per channel continuously when only one channel is active at Ta = 25°C on a standard PCB. At 85°C ambient with all 7 channels active and 10% duty cycle, the limit drops to 300 mA per channel due to thermal derating constraints specified in the datasheet.
Does TBD62304AFNG,EL include built-in protection circuits?
No, the TBD62304AFNG,EL does not incorporate built-in overcurrent, overvoltage, or thermal protection circuits. External fuses must be placed in the VCC line, and flyback diodes are required for inductive loads to prevent damage from back-EMF-per Toshiba's explicit usage precautions.
What is the recommended input voltage range to activate an output on TBD62304AFNG,EL?
To turn on an output, apply VIN ≤ VCC−3.5 V (e.g., ≤1.5 V at VCC = 5.0 V). The device accepts inputs down to −20 V, supporting direct interface with open-collector drivers or negative logic sources without level shifters.
Can TBD62304AFNG,EL drive 24 V relay coils directly?
Yes, the TBD62304AFNG,EL's 50 V output voltage rating allows direct connection to 24 V DC relay coils. However, a flyback diode must be placed across each coil to suppress inductive kickback, as the IC lacks internal clamp diodes.
What is the thermal derating coefficient for TBD62304AFNG,EL in its SSOP package?
The TBD62304AFNG,EL has a thermal derating coefficient of 6.24 mW/°C above 25°C when mounted on a 50 mm × 50 mm × 1.6 mm PCB with 40% copper area. This means its usable power dissipation decreases linearly beyond ambient 25°C, requiring careful thermal margining in enclosed enclosures.
