Product details

Overview

ZX5T853GTA from Diodes Incorporated is a 100V NPN medium-power low-saturation transistor in SOT223 package, rated for 6A continuous collector current and 10A peak pulse current, with V_CE(sat) < 35mV at 5A and h_FE ≥ 10 at 10A - deployed as high-side switch in automotive motor drivers and industrial line-switching circuits.

For engineers reviewing the ZX5T853GTA datasheet, ZX5T853GTA pinout, ZX5T853GTA application, or ZX5T853GTA equivalent, key selection criteria include verified AEC-Q101 qualification, low R_SAT = 36mΩ at 6A, thermal resistance R_θJA = 42°C/W (on 52mm × 52mm PCB), and complementary PNP pairing with ZX5T953G.

Technical Context

This NPN bipolar junction transistor operates in linear and switching modes with BV_CEO = 100V and BV_CBO = 200V, enabling robust operation in 24–48V industrial power rails. Its h_FE remains ≥10 up to I_C = 10A, supporting stable gain under high-current saturation conditions.

V_CE(sat) is specified at 21–35mV (typ/max) across I_C = 100mA–5A with corresponding base drive, and f_T = 130MHz ensures adequate bandwidth for fast-switching applications such as PWM-controlled DC motors and solenoid drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	100 V - supports operation in 48V nominal systems with 2× safety margin
I_C (continuous)	6 A - enables direct drive of small DC motors and relay coils without heatsinking
V_CE(sat) @ 5A	≤ 220 mV - yields < 1.1W conduction loss at full load, reducing thermal stress
h_FE @ 10A	≥ 10 - ensures sufficient current gain for reliable saturation with moderate base drive
R_θJA	42 °C/W - requires minimal copper area (52mm × 52mm, 2oz) for ≤100°C junction rise at 3W
f_T	130 MHz - supports switching frequencies up to ~10 MHz with acceptable gain roll-off
ESD HBM	4000 V - meets IEC 61000-4-2 Level 3 for board-level ESD robustness

Pinout & Package

Package: SOT223 - surface-mount plastic case with exposed collector tab for thermal enhancement; 0.112g mass; UL 94V-0 rated molding compound; moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	Current sink terminal	Connected to ground or low-side return path; electrically isolated from tab
Pin 2 (Base)	Control input	Receives current-limited drive (IB ≈ IC/10); requires series resistor for TTL/CMOS interfacing
Pin 3 (Collector)	High-current output	Internally bonded to exposed metal tab - must be soldered to PCB copper for thermal conduction
Tab (Collector)	Thermal & electrical node	Primary heat path to PCB; electrically identical to Pin 3; requires isolation if mounted to heatsink

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22
Low V_CE(sat)	21 mV typ @ 5A - reduces conduction loss by >40% vs. standard general-purpose transistors
High I_CM	10 A peak - sustains short-duration inrush currents in motor startup and solenoid actuation
Green construction	Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - compliant with EU ELV and RoHS 2
Exposed collector tab	Thermal resistance R_θJL = 10.5°C/W - enables efficient heat transfer to PCB without external heatsink

Applications

Automotive Motor Drivers

Industrial Line Switching

Use Scenario: Driving 12–48V brushed DC motors in seat adjusters, window lifts, and HVAC actuators.

IC Role / Device Role / Timing Role: High-side NPN switch controlling motor voltage rail with PWM duty cycle modulation.

Use Value: Low V_CE(sat) minimizes self-heating during 100% duty-cycle hold; AEC-Q101 rating ensures 15-year field reliability.

Use Scenario: Solid-state replacement for electromechanical relays in PLC output modules and building automation panels.

IC Role / Device Role / Timing Role: Load switch isolating AC/DC loads up to 6A with fast turn-on/turn-off (t_on = 41ns, t_off = 1010ns).

Use Value: Eliminates contact wear and bounce; 100V V_CEO accommodates 75V transients on 48V lines per IEC 61000-4-5.

High-Side Power Switches

Power Supply OR-ing Circuits

Use Scenario: Controlling power delivery to subsystems (e.g., infotainment, ADAS sensors) from main battery rail.

IC Role / Device Role / Timing Role: NPN-based high-side switch with base resistor network for controlled slew rate and shoot-through prevention.

Use Value: 6A continuous rating supports multi-rail power domains; R_θJA = 42°C/W allows operation at +85°C ambient without derating.

Use Scenario: Diode-replacement OR-ing in redundant 24V DC power supplies for telecom and server backplanes.

IC Role / Device Role / Timing Role: Low-V_CE(sat) NPN used in active OR-ing configuration with external control logic.

Use Value: 35mV max V_CE(sat) cuts forward drop by >85% vs. Schottky diodes, improving efficiency and reducing thermal footprint.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN medium-power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZX5T953G	Complementary PNP device; same package, V_CEO = 100V, I_C = 6A, V_CE(sat) ≤ 45mV	Used in push-pull or H-bridge topologies requiring matched NPN/PNP pairs	Select when designing bidirectional current control or dual-rail switching stages
MJD127	TO-220 package; V_CEO = 100V, I_C = 8A, V_CE(sat) = 1.5V @ 4A - significantly higher saturation voltage	Requires heatsink; suited for lower-frequency, higher-current legacy designs	Choose only if SOT223 footprint is incompatible and thermal budget permits higher loss

Compared with ZX5T953G, this part provides NPN polarity and tighter V_CE(sat); versus MJD127, it delivers 95% lower conduction loss in SMT form factor but trades off maximum current headroom for thermal efficiency.

FAQ

What is the maximum allowable junction temperature for ZX5T853GTA?

The absolute maximum operating junction temperature is +150°C, with storage range matching at –55°C to +150°C. Derating begins above +25°C ambient at 24 mW/°C (for 52mm × 52mm PCB layout), ensuring safe operation up to +125°C ambient at 1.6W dissipation.

Can ZX5T853GTA be used in parallel configurations?

Parallel operation is not recommended due to positive temperature coefficient of V_CE(sat) - unlike MOSFETs, BJTs exhibit current hogging under thermal imbalance. If required, forced current sharing via individual emitter resistors and matched layout is mandatory, with derating of total current by ≥30%.

Is the exposed collector tab electrically isolated from the PCB copper pour?

No - the SOT223 collector tab is internally bonded to Pin 3 and is electrically identical to the collector terminal. When soldered to a PCB copper pour, that pour becomes part of the collector net and must be routed accordingly; insulation is required if mounting to an external heatsink.

Does ZX5T853GTA support 100% duty cycle operation at 6A?

Yes, provided thermal design meets R_θJA ≤ 42°C/W: at 6A and V_CE(sat) = 220mV, power dissipation is 1.32W, resulting in ΔT_J-A = 55.4°C - keeping T_J ≤ 80°C at +25°C ambient. Derating is required above +70°C ambient.
