Product details
Overview
BZT52C2V7SQ-7-F from Diodes Incorporated is a surface-mount Zener diode with nominal 2.7 V zener voltage (2.5–2.9 V range), 5 mA test current, 100 Ω maximum zener impedance at 1 kHz, and 200 mW power dissipation in SOD323 package. It provides precision voltage regulation in low-power biasing and reference circuits for automotive sensor interfaces.
For engineers reviewing the BZT52C2V7SQ-7-F datasheet, BZT52C2V7SQ-7-F pinout, BZT52C2V7SQ-7-F application, or BZT52C2V7SQ-7-F equivalent, key selection criteria include zener voltage tolerance (±3.7%), reverse leakage (20 µA @ 1.0 V), temperature coefficient (−3.5 to 0 mV/°C), and AEC-Q101 qualification for automotive reliability.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown when cathode-to-anode voltage exceeds its specified zener voltage. Its planar die construction ensures stable breakdown characteristics and low dynamic impedance across operating temperature (−65 °C to +150 °C).
The SOD323 package enables high-density PCB layouts and compatibility with automated reflow assembly. Thermal resistance of 625 °C/W (junction-to-ambient) requires careful power derating above +25 °C ambient, per the published derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal, 2.5–2.9 V range at 5 mA - defines stable regulation point for low-voltage references |
| Power Dissipation (PD) | 200 mW - limits continuous DC or pulsed power in compact SOD323 footprint |
| Zener Impedance (ZZT) | ≤100 Ω at 1 kHz - ensures minimal AC ripple in regulated output under dynamic load |
| Reverse Leakage (IR) | 20 µA @ 1.0 V - determines quiescent current draw in standby bias networks |
| Temp. Coefficient (TC) | −3.5 to 0 mV/°C - indicates slight negative drift, requiring compensation in precision analog rails |
| Package | SOD323 - 1.3 × 1.7 mm outline, 0.3 mm typical height, compatible with IPC-7351B standard footprints |
Pinout & Package
SOD323 package with cathode band marking; two-terminal device with anode and cathode leads formed from alloy 42 leadframe, matte tin finish, solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Sensor Biasing | Low-Voltage Microcontroller Reset Circuit |
|---|---|
Use Scenario: Providing stable 2.7 V reference to analog front-end of pressure or temperature sensors in engine bay environments. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference, clamping sensor supply rail against transients while maintaining accuracy over −40 °C to +125 °C. Use Value: Enables ±1% sensor output linearity by holding reference within 2.5–2.9 V across temperature and supply variation. | Use Scenario: Generating clean reset threshold for 3.3 V microcontrollers where internal brown-out detection lacks sufficient hysteresis. IC Role / Device Role / Timing Role: Functions as external reset supervisor element, triggering POR when VCC drops below 2.7 V ±0.2 V. Use Value: Reduces false resets by 40% compared to RC-based solutions due to sharp knee and low ZZT. |
| USB-C Port Overvoltage Clamp | Industrial I/O Module Signal Conditioning |
Use Scenario: Protecting USB-C CC line receivers from ESD-induced overvoltage events up to ±8 kV contact discharge. IC Role / Device Role / Timing Role: Fast-acting shunt clamp placed between CC pin and ground, absorbing transient energy before IC input damage occurs. Use Value: Limits peak clamped voltage to ≤3.0 V, staying within receiver absolute maximum rating of 3.6 V. | Use Scenario: Stabilizing 2.7 V bias for op-amp input stages in 4–20 mA loop-powered transmitters operating at 12 V supply. IC Role / Device Role / Timing Role: Supplies precise, low-noise reference to instrumentation amplifier gain-setting network. Use Value: Improves current-loop accuracy to ±0.1% FSR by minimizing reference drift over 0–70 °C industrial range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5223BS-7-F | Zener voltage 2.7 V (2.5–2.9 V), same SOD323 package, but 350 mW PD, higher IZK (200 µA) | Higher power handling suits intermittent surge clamping; less suitable for low-IR bias networks | Select when >200 mW pulse energy absorption is required; verify thermal layout for sustained dissipation |
| BZX384-B2V7,115 | Zener voltage 2.7 V (2.57–2.83 V), SOD323, 300 mW PD, but only commercial qualification (not AEC-Q101) | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules | Acceptable for consumer or industrial non-automotive designs where AEC-Q101 is not mandated |
Compared with BZT52C2V7SQ-7-F, MMBZ5223BS-7-F offers higher surge capability but looser leakage control, while BZX384-B2V7,115 trades automotive reliability for marginally tighter VZ tolerance - making the original optimal for cost-sensitive, AEC-Q101-compliant 2.7 V reference needs.

FAQ
What is the maximum reverse leakage current for BZT52C2V7SQ-7-F at 1.0 V?
The maximum reverse leakage current is 20 µA at 1.0 V, measured at +25 °C ambient. This value remains ≤50 µA across the full operating temperature range (−65 °C to +150 °C), ensuring predictable quiescent behavior in battery-powered systems.
Is BZT52C2V7SQ-7-F suitable for use in a 5 V rail overvoltage clamp?
No - its 2.7 V zener voltage makes it unsuitable as a primary clamp on a 5 V rail. It would conduct prematurely and fail to protect downstream components. For 5 V clamping, select a part with VZ ≥5.6 V (e.g., BZT52C5V6SQ-7-F) to allow normal operation while clamping above the rail.
Does the "Q" in BZT52C2V7SQ-7-F indicate automotive qualification?
Yes - the "Q" suffix denotes AEC-Q101 qualification per Diodes Incorporated's ordering nomenclature. This part meets stress testing requirements for temperature cycling, humidity, mechanical shock, and high-temperature operating life applicable to automotive electronics.
Can BZT52C2V7SQ-7-F replace BZT52C2V4SQ-7-F in a precision reference circuit?
No - the 2.7 V unit has a different zener voltage range (2.5–2.9 V vs. 2.2–2.6 V), resulting in ~12% higher reference level. Substitution would shift bias points, alter gain calibration, and likely cause system-level functional failure unless circuit recalibration is performed.
