Product details
Overview
BZT52C2V7S-7-F from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 2.7 V, ±7% tolerance (2.5–2.9 V), 200 mW power dissipation, and 100 Ω dynamic impedance at 5 mA test current. It operates across –65 °C to +150 °C and is qualified to AEC-Q101 for automotive reliability, used in voltage regulation and overvoltage protection circuits on compact PCBs.
For engineers reviewing the BZT52C2V7S-7-F datasheet, BZT52C2V7S-7-F pinout, BZT52C2V7S-7-F application, or BZT52C2V7S-7-F equivalent, key selection criteria include zener voltage accuracy at low current (20 µA reverse leakage at 1.0 V), thermal resistance (625 °C/W), SOD323 package footprint compatibility, and halogen/antimony-free "Green" compliance for automotive and industrial designs.
Technical Context
This Zener diode functions as a precision shunt voltage reference in low-power biasing and clamping applications. Its planar die construction ensures stable breakdown characteristics, while the SOD323 package enables high-density placement and automated reflow assembly.
The device exhibits a negative temperature coefficient of –3.5 mV/°C and maintains ≤1.0 µA reverse current at VR = 1.0 V, supporting accurate low-voltage regulation in battery-powered sensors and microcontroller I/O protection circuits where thermal drift and leakage must be tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal, 2.5–2.9 V range at IZT = 5 mA - defines regulated output level in shunt regulator topologies |
| Power Dissipation (PD) | 200 mW at TA = 25 °C - limits maximum continuous power in ambient-convection cooling |
| Zener Impedance (ZZT) | 100 Ω at f = 1 kHz, IZT = 5 mA - determines regulation stiffness under load transients |
| Reverse Leakage (IR) | 20 µA max at VR = 1.0 V - critical for low-power standby circuits and signal-level clamping |
| Thermal Resistance (RθJA) | 625 °C/W - defines junction-to-ambient temperature rise per watt, guiding PCB copper area design |
| Operating Temperature | –65 °C to +150 °C - supports under-hood automotive and industrial environments without derating |
| Package | SOD323 - 1.3 × 1.7 mm footprint, 0.3 mm typical height, compatible with 0402-class pick-and-place |
Pinout & Package
Two-terminal SOD323 package with cathode band marking; no internal pin numbering-cathode (banded end) and anode (unmarked end) are defined by physical polarity marking only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to reference voltage rail; sinks current during zener conduction |
| Anode (unmarked end) | Reference ground node | Typically tied to system ground or lower-potential rail in shunt configuration |
Key Features

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, same SOD323 package, but 350 mW PD and higher IR (50 µA @ 1 V) | Higher power handling suits transient suppression; higher leakage limits use in nanoamp sensor nodes | Select when surge energy absorption >200 mW is required and leakage tolerance >20 µA is acceptable |
| BZX384-B2V7,115 | Zener voltage 2.7 V, SOD323 package, 250 mW PD, but ±5% tolerance (2.57–2.84 V) and no AEC-Q101 qualification | Commercial-grade only; unsuitable for automotive applications requiring qualification traceability | Select for cost-sensitive consumer electronics where AEC-Q101 is not mandated |
Compared with MMBZ5223BS-7-F and BZX384-B2V7,115, BZT52C2V7S-7-F offers tighter voltage tolerance (±7% vs ±5% or ±10%), guaranteed AEC-Q101 compliance, and lowest reverse leakage-making it optimal for automotive and precision low-power regulation where qualification and leakage are decisive.

FAQ
What is the maximum reverse current at 1.0 V for BZT52C2V7S-7-F?
The maximum reverse current (IR) is 20 µA at VR = 1.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains stable across the full operating temperature range and is critical for low-leakage bias networks in battery-powered systems.
Is BZT52C2V7S-7-F suitable for reflow soldering in lead-free processes?
Yes-its matte tin finish is solderable per MIL-STD-202, Method 208, and the SOD323 package is rated for standard Pb-free reflow profiles (peak 260 °C). Moisture sensitivity level is Grade 1, eliminating pre-bake requirements and supporting direct placement into high-volume SMT lines.
Does this Zener diode have a positive or negative temperature coefficient?
BZT52C2V7S-7-F has a negative temperature coefficient of –3.5 mV/°C, meaning its zener voltage decreases linearly with rising junction temperature. This behavior is consistent across the entire 2.0 V–39 V BZT52C series and must be accounted for in precision reference designs above 50 °C ambient.
Can BZT52C2V7S-7-F replace BZT52C2V4S-7-F in a circuit?
No-while both share identical package and construction, their zener voltages differ (2.7 V vs 2.4 V) and tolerance bands do not overlap. Substitution would shift regulation point by 12.5%, potentially causing undervoltage lockout or ADC reference errors; redesign validation is required if changing voltage grade.
