Product details
Overview
BZT52C2V0SQ-7-F from Diodes Incorporated is a surface-mount Zener diode with nominal 2.0 V zener voltage (1.91–2.09 V at 5 mA), 200 mW power dissipation, and SOD323 package. It provides precision voltage regulation in low-power biasing, reference, and overvoltage protection circuits for automotive and industrial control modules.
For engineers reviewing the BZT52C2V0SQ-7-F datasheet, BZT52C2V0SQ-7-F pinout, BZT52C2V0SQ-7-F application, or BZT52C2V0SQ-7-F equivalent, key selection criteria include zener voltage tolerance (±4.5%), low dynamic impedance (100 Ω at 5 mA), temperature coefficient (−3.5 to 0 mV/°C), cathode-band polarity marking, and AEC-Q101 qualification for automotive reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying current loads. Its planar die construction ensures consistent breakdown characteristics, while the SOD323 package supports high-density PCB layouts and automated reflow assembly.
It delivers regulated reference voltage with 150 µA maximum reverse leakage at VR = 1.0 V and exhibits a thermal resistance of 625 °C/W (junction-to-ambient) on FR-4 board with recommended pad layout. The device is halogen- and antimony-free, qualified to AEC-Q101, and rated for operation from −65 °C to +150 °C.
Key Specifications

Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Voltage reference for analog-to-digital converter input scaling in door module microcontrollers. IC Role / Device Role / Timing Role: Provides stable 2.0 V reference to offset and scale thermistor or potentiometer signals. Use Value: Enables ±1% measurement accuracy over −40 °C to +125 °C ambient due to low TC and AEC-Q101 stability. | Use Scenario: Overvoltage clamp protecting 3.3 V I/O pins of PLC analog input ICs from transient surges. IC Role / Device Role / Timing Role: Shunts excess energy above 2.09 V to ground before damage occurs to downstream logic. Use Value: Limits clamping voltage to ≤2.09 V with 100 Ω dynamic impedance, reducing risk of latch-up in 3.3 V CMOS interfaces. |
| USB-C Power Delivery Monitor | Low-Power Wearable Battery Management |
Use Scenario: Biasing network for voltage divider feeding USB PD controller feedback pin. IC Role / Device Role / Timing Role: Sets accurate 2.0 V threshold for VBUS presence detection and fault reporting. Use Value: Maintains detection accuracy within ±0.09 V over full temperature range, avoiding false disconnect events. | Use Scenario: Reference source for lithium-ion cell voltage monitoring in hearable devices. IC Role / Device Role / Timing Role: Supplies stable reference to comparator detecting end-of-charge or over-discharge thresholds. Use Value: Delivers 2.0 V reference with <150 µA leakage at 1.0 V reverse bias, minimizing standby current drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Zener voltage 2.0 V (same nominal), but 350 mW PD, SOT-23 package, non-AEC-Q101 | Higher power handling; unsuitable for automotive-grade designs requiring AEC validation | Select when board space allows larger SOT-23 and automotive qualification is not required |
| BZX384-B2V0,115 | Zener voltage 2.0 V, 250 mW PD, SOD-323 package, AEC-Q101 qualified, but ±5% tolerance (vs. ±4.5%) | Same footprint and qualification; slightly wider VZ spread impacts precision reference use | Acceptable where ±5% regulation tolerance meets system error budget |
Compared with MMBZ5221BS-7-F and BZX384-B2V0,115, BZT52C2V0SQ-7-F offers tighter voltage tolerance (±4.5%), identical SOD323 footprint, and AEC-Q101 validation-making it optimal for space-constrained automotive and industrial reference designs demanding high repeatability.

FAQ
What is the maximum reverse leakage current for BZT52C2V0SQ-7-F at 1.0 V?
The maximum reverse leakage current (IR) is 150 µA at VR = 1.0 V and TA = +25°C, per the Electrical Characteristics table in DS30093 Rev. 20-2. This value ensures minimal loading on high-impedance bias networks in precision reference applications.
Is BZT52C2V0SQ-7-F suitable for reflow soldering?
Yes-it is qualified for standard lead-free reflow profiles per J-STD-020 Level 1 moisture sensitivity, with matte tin finish on Alloy 42 leadframe ensuring reliable solderability. The SOD323 package withstands peak temperatures up to 260°C for ≤10 seconds.
How does the temperature coefficient affect regulation accuracy?
The temperature coefficient ranges from −3.5 to 0 mV/°C, meaning VZ may decrease by up to 0.35 V over a 100°C rise (e.g., −40°C to +60°C). For applications requiring <1% drift, this must be factored into reference circuit error budgets.
What does the 'Q' in BZT52C2V0SQ-7-F signify?
The 'Q' denotes automotive qualification per AEC-Q101 standards, distinguishing it from commercial-grade variants like BZT52C2V0S-7-F. This includes extended temperature testing, reliability stress screening, and traceability requirements mandated for automotive electronics.
