Product details
Overview
BZT52C2V7-13 from Diodes Incorporated is a surface-mount Zener diode with nominal 2.7 V zener voltage, 5 mA test current, and ±0.2 V tolerance (2.5–2.9 V), rated for 370 mW power dissipation at 25°C ambient and packaged in SOD123. It provides precise low-voltage regulation in power supply feedback paths, voltage reference circuits, and overvoltage protection for microcontroller I/O pins.
For engineers reviewing the BZT52C2V7-13 datasheet, BZT52C2V7-13 pinout, BZT52C2V7-13 application, or BZT52C2V7-13 equivalent, key selection criteria include zener voltage accuracy at 5 mA, low dynamic impedance (≤100 Ω), temperature coefficient (−3.5 mV/°C), reverse leakage (≤20 µA @ 1.0 V), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics and low leakage, while the SOD123 package supports automated placement and offers thermal resistance of 338°C/W (junction-to-ambient) on FR-4 PCB.
The device exhibits a negative temperature coefficient of −3.5 mV/°C, making it suitable for temperature-compensated references when paired with positive-TC components. At 5 mA test current, it achieves zener impedance ≤100 Ω and maintains reverse current ≤20 µA at 1.0 V, enabling reliable clamping in low-power sensing and biasing circuits.

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 | Same 2.7 V nominal, but SOT-23 package (higher thermal resistance: 400°C/W); 200 mW PD rating | Limited to lower-power applications due to reduced power handling and less robust thermal performance | Select when board space is constrained and power <150 mW; avoid in automotive under-hood use |
| BZX384-C2V7 | 2.7 V, SOD-323 package, 300 mW PD, higher ZZT (120 Ω), non-AEC-Q101 qualified | Suitable only for commercial-grade consumer electronics; not validated for automotive stress profiles | Choose for cost-sensitive consumer designs where AEC-Q101 and thermal margin are not required |
Compared with MMBZ5223BS-7-F and BZX384-C2V7, BZT52C2V7-13 delivers superior thermal performance (338°C/W), higher power capability (370 mW), AEC-Q101 qualification, and tighter zener impedance - making it the preferred choice for automotive and industrial applications demanding reliability and stability.

FAQ
What is the maximum reverse current for BZT52C2V7-13 at 1.0 V?
The maximum reverse current (IR) is 20 µA at VR = 1.0 V and TA = +25°C, per the Electrical Characteristics table. This low leakage ensures minimal power loss in always-on monitoring circuits and preserves battery life in portable devices.
Is BZT52C2V7-13 suitable for automotive applications?
Yes - it is qualified to AEC-Q101 standards and rated for operating temperatures from −65°C to +150°C. Its SOD123 package, lead-free plating, and moisture sensitivity Level 1 make it appropriate for under-hood and body electronics modules.
How does the −3.5 mV/°C temperature coefficient affect circuit performance?
This negative coefficient means the zener voltage decreases by 3.5 mV per degree Celsius rise. In precision references, it must be compensated - e.g., by pairing with a forward-biased diode or using in temperature-stable environments like indoor industrial controls.
What is the recommended PCB pad layout for SOD123 mounting?
Per Diodes' package outline, use X = 0.900 mm (pad width), X1 = 4.050 mm (pad length), and Y = 0.950 mm (pad spacing). This layout ensures reliable solder joint formation and thermal dissipation matching the 338°C/W RθJA specification.
