Product details
Overview
FMMT723QTA from Diodes Incorporated is a 100V PNP low-saturation transistor in SOT23 package, designed for high-side switching and load disconnect applications. It delivers -1A continuous collector current, -330mV VCE(sat) at -1A, and 210mΩ equivalent on-resistance, with AEC-Q101 qualification for automotive reliability.
For engineers reviewing the FMMT723QTA datasheet, FMMT723QTA pinout, FMMT723QTA application, or FMMT723QTA equivalent, key selection criteria include its -100V VCEO, -1A IC, low RCE(SAT), AEC-Q101 compliance, and SOT23 thermal performance under pulsed and DC conditions.
Technical Context
This PNP bipolar junction transistor operates as a high-voltage, high-current switch with characterized hFE up to -1.5A and guaranteed BVCEO ≥ -100V. Its low saturation voltage and on-resistance enable efficient power control in constrained space.
The device uses standard SOT23 packaging with matte tin-plated leads and meets J-STD-020 Level 1 moisture sensitivity. Thermal resistance is 155°C/W (J-A, t ≤ 5s) and 194°C/W (J-L), supporting stable operation from -55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -100 V - Withstands 100V collector-emitter reverse bias without breakdown in switching applications |
| IC (continuous) | -1 A - Supports sustained 1A load current in high-side driver circuits |
| VCE(sat) | < -330 mV @ -1A - Minimizes conduction loss and self-heating during active switching |
| RCE(SAT) | 210 mΩ - Enables precise on-state resistance modeling for power budgeting |
| hFE | 30–250 @ -1A to -1.5A - Provides predictable base drive requirements across full operating range |
| fT | 150–200 MHz - Supports fast switching in motor drive and PWM control loops |
| PD (t ≤ 5s) | 806 mW - Allows short-duration peak power handling beyond steady-state limits |
Pinout & Package
Package: SOT23 - Surface-mount plastic case, 0.008 g weight, UL 94V-0 rated, lead-free and halogen-free "Green" compound.

| 3 (Collector) | Switched output terminal | Connected to load; voltage swings between near-ground and -100V during operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments including temperature cycling, humidity, and vibration stress |
| Low RCE(SAT) | 210mΩ enables <100mW conduction loss at 1A, reducing thermal design margin requirements |
| High VCEO | -100V rating supports 48V and 60V industrial bus systems with safety margin |
| Characterized hFE to -1.5A | Ensures predictable base drive sizing across full load range without gain collapse |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP high-voltage switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FMMT718QTA | VCEO = -60V, IC = -0.5A, VCE(sat) = -200mV @ -0.5A | Limited to lower-voltage 24V systems; reduced current capacity | Select when lower cost and reduced voltage margin are acceptable |
| ZXTN2012ZTA | PNP, VCEO = -100V, IC = -1.5A, but SOT89 package (higher thermal mass) | Requires larger PCB footprint; better steady-state thermal dissipation (RθJA ≈ 100°C/W) | Select when >625mW continuous power or improved thermal management is required |
Compared with FMMT718QTA, FMMT723QTA offers higher voltage and current ratings; compared with ZXTN2012ZTA, it trades thermal performance for compact SOT23 size-ideal for space-constrained automotive modules.

FAQ
What is the maximum continuous collector current for FMMT723QTA?
The maximum continuous collector current is -1 A at TA = +25°C with appropriate PCB copper area. Derating applies above 25°C ambient per the datasheet curve: power dissipation drops linearly to zero at 150°C junction temperature.
Is FMMT723QTA pin-compatible with FMMT718QTA?
Yes-both use identical SOT23 pinout (Emitter-Base-Collector on pins 1-2-3). However, FMMT723QTA has higher VCEO (-100V vs. -60V) and IC (-1A vs. -0.5A), so substitution requires verification of voltage margin and thermal headroom.
Does FMMT723QTA require a heatsink in typical automotive applications?
No external heatsink is required. With RθJA = 155°C/W (t ≤ 5s) and 625mW steady-state power, a standard 25mm × 25mm 1oz copper pad provides sufficient thermal relief for most 1A pulsed or DC loads below 85°C ambient.
What is the base drive requirement to fully saturate FMMT723QTA at -1A collector current?
Full saturation at -1A requires -150mA base current, yielding VCE(sat) ≤ -330mV. Base-emitter saturation voltage is -0.89V typical under this condition, so drive circuitry must sink ≥150mA at ~0.9V forward drop.
