Product details
Overview
ZRC330QF01TA from Diodes Incorporated is an automotive-grade, bandgap-based precision voltage reference delivering 3.3 V ±1% at +25°C with 15 µA typical knee current, 0.6 Ω typical slope resistance, and operation from −40°C to +125°C - used as a stable reference in automotive instrumentation and data acquisition systems.
For engineers reviewing the ZRC330QF01TA datasheet, ZRC330QF01TA pinout, ZRC330QF01TA application, or ZRC330QF01TA equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, capacitor-free stability, low-power operation (20 µA–5 mA), and 3.3 V reference tolerance under automotive thermal and transient stress.
Technical Context
The ZRC330QF01TA implements a bandgap reference architecture optimized for low-knee-current startup and high-temperature stability, achieving ±15 ppm/°C to ±50 ppm/°C temperature coefficient over −40°C to +125°C. It operates without external stabilization capacitance and maintains regulation under capacitive loads up to 25 mA.
Its rugged design supports transient currents up to 200 mA and achieves stable output within microseconds. The device uses a two-terminal configuration (VR and GND) with Pin 1 floating or tied to GND, enabling compact SOT23 layout in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 3.3 V ±1% at +25°C - ensures accurate ADC/DAC biasing in automotive sensor interfaces |
| Knee Current | 15 µA typical - enables reliable startup in ultra-low-power wake-up circuits |
| Slope Resistance | 0.6 Ω typical - minimizes load-induced voltage shift across 20 µA–5 mA operating range |
| Temp Coefficient | 15–50 ppm/°C - maintains <±3 mV drift over full −40°C to +125°C automotive range |
| Operating Current | 20 µA to 5 mA - supports both battery-backed standby and active measurement modes |
| ESD Rating | HBM 4 kV - meets automotive board-level ESD robustness requirements |
| Qualification | AEC-Q100 Grade 1 - validated for under-hood applications up to +125°C ambient |
Pinout & Package
Supplied in SOT23 package (3-pin, 2-terminal configuration), with Pin 1 unused (floating or tied to Pin 2), Pin 2 as GND, and Pin 3 as VR output terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | No-connect / optional GND tie | Not electrically active; left floating or shorted to Pin 2 for mechanical stability |
| Pin 2 | GND | Reference ground return path; must be low-impedance for noise immunity |
| Pin 3 | VR (Output) | 3.3 V regulated output; drives ADC references, sensor excitation, or comparator thresholds |
Key Features
| Feature | Design Value |
|---|---|
| Capacitor-free operation | Stable without external bypass cap - reduces BOM count and PCB area in instrument clusters |
| Low knee current | 15 µA typical - enables use in always-on vehicle subsystems with microamp quiescent budgets |
| Fast turn-on | Microsecond-scale stabilization - supports burst-mode sensing and rapid system wake-up |
| AEC-Q100 Grade 1 | Qualified from −40°C to +125°C junction - suitable for engine control and transmission modules |
| Transient robustness | Withstands 200 mA surge - survives load-dump and jump-start events in 12 V automotive systems |
Applications

Use Value: ±1% tolerance and <50 ppm/°C drift prevent audible distortion during cabin temperature cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV431AIDBZR | Adjustable shunt reference (2.5 V min), 1.5% initial tolerance, higher 600 mV dropout at 100 µA | Requires external resistors for 3.3 V setting; less stable at ultra-low current | Choose when adjustable output or higher current (>10 mA) is needed |
| MAX6033AESA+ | Fixed 3.3 V series reference, ±0.2% initial tolerance, 75 ppm/°C TC, requires 1 µF output cap | Higher precision but capacitor-dependent stability; not qualified to AEC-Q100 | Choose when tighter tolerance outweighs automotive qualification needs |
Compared with TLV431AIDBZR and MAX6033AESA+, the ZRC330QF01TA uniquely combines AEC-Q100 Grade 1 qualification, capacitor-free operation, and 15 µA knee current - making it optimal for space- and power-constrained automotive modules where reliability and simplicity are critical.
