Product details

Overview

BZT52C2V0S-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 portable electronics and sensor interfaces.

For engineers reviewing the BZT52C2V0S-7-F datasheet, BZT52C2V0S-7-F pinout, BZT52C2V0S-7-F application, or BZT52C2V0S-7-F equivalent, key selection criteria include zener voltage tolerance (±4.5%), low dynamic impedance (100 Ω at 5 mA), cathode-band polarity marking, AEC-Q101 qualification, and RoHS-compliant green packaging.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under controlled current conditions. Its planar die construction ensures consistent breakdown characteristics, while the SOD323 package enables high-density PCB layouts and compatibility with automated reflow assembly.

The device exhibits a negative temperature coefficient of −3.5 mV/°C, enabling predictable drift compensation in temperature-sensitive references. With 150 µA maximum reverse leakage at 1.0 V and 100 Ω typical zener impedance at 5 mA, it delivers tight regulation in low-current (<10 mA) applications.

Zener Impedance (Z_ZT)	100 Ω max at 1 kHz, 5 mA - determines regulation stiffness under load transients
Reverse Leakage (I_R)	150 µA max at V_R = 1.0 V - impacts quiescent current in high-impedance bias networks

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBZ5221BS-7-F	Zener voltage 2.0 V (same tolerance), but 350 mW P_D, SOT-23 package	Larger footprint and higher thermal mass; less suitable for ultra-dense layouts	Select when higher power margin or legacy SOT-23 board compatibility is required
BZX384-B2V0,115	Zener voltage 2.0 V, 250 mW P_D, SOD-323 package, but ±5% tolerance (vs. ±4.5%)	Higher leakage (200 µA @ 1 V) and no AEC-Q101 qualification	Select for cost-sensitive industrial applications where automotive qualification is unnecessary

Compared with MMBZ5221BS-7-F and BZX384-B2V0,115, BZT52C2V0S-7-F offers tighter voltage tolerance, automotive qualification, and optimal thermal performance in minimal area-making it preferred for space-constrained, safety-aware designs.

FAQ

What is the maximum reverse leakage current for BZT52C2V0S-7-F at 1.0 V?

The maximum reverse leakage current is 150 µA at V_R = 1.0 V and T_A = +25°C, as specified in the Electrical Characteristics table. This value increases slightly with temperature but remains below 300 µA up to +85°C, ensuring minimal loading in high-impedance reference networks.

Is BZT52C2V0S-7-F suitable for use in automotive applications?

Yes - it is qualified to AEC-Q101 standards, including stress tests for temperature cycling, high-temperature reverse bias, and humidity resistance. Its SOD323 package and green material set meet automotive PCB assembly and environmental compliance requirements.

How does the −3.5 mV/°C temperature coefficient affect circuit design?

This negative coefficient means the zener voltage decreases by 3.5 mV per °C rise in junction temperature. In precision references, designers compensate using series resistors or complementary positive-TC components to achieve net zero drift across the operating range.

What is the recommended pad layout for SOD323 mounting?

Diodes Incorporated specifies a pad layout with X = 0.590 mm, Y = 0.450 mm, X1 = 2.700 mm, and thermal relief for the cathode pad. The layout follows IPC-7351B generic SOD323 footprint and supports reflow profiles compliant with J-STD-020 Level 1 moisture sensitivity.
