Product details
Overview
BZT52C2V7-13-F from Diodes Incorporated is a surface-mount 2.7 V Zener diode in SOD123 package, rated for 500 mW peak power dissipation at TL = +75°C and 370 mW at TA = +25°C, with 100 Ω maximum Zener impedance at 5 mA test current and ±0.2 V zener voltage tolerance (2.5–2.9 V). It serves as a precision voltage reference or overvoltage clamp in low-power analog sensor signal conditioning circuits.
For engineers reviewing the BZT52C2V7-13-F datasheet, BZT52C2V7-13-F pinout, BZT52C2V7-13-F application, or BZT52C2V7-13-F equivalent, key selection criteria include its 2.7 V nominal breakdown voltage, 20 µA maximum reverse leakage at 1.0 V, -3.5 mV/°C temperature coefficient, SOD123 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage across load variations and supply fluctuations. Its planar die construction ensures consistent breakdown characteristics and low dynamic impedance (100 Ω @ 5 mA), while the SOD123 package supports automated placement and reflow soldering with JEDEC-compliant thermal performance.
Designed for medium-current general-purpose regulation, it delivers predictable clamping behavior under transient conditions-e.g., ESD protection in I/O lines or bias stabilization in op-amp feedback networks-with verified thermal resistance of 338 °C/W (junction-to-ambient) on FR-4 PCBs.

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 VZ, but SOT-23 package (3-pin, smaller footprint); 350 mW PD @ TA; 120 Ω ZZT | Higher board density possible, but lower power handling and no AEC-Q101 qualification | Select when space-constrained PCB layout outweighs automotive qualification and thermal margin needs |
| BZX84-C2V7 | 2.7 V VZ, SOT-23 package, 300 mW PD @ TA, 150 Ω ZZT, non-AEC-Q101 | Limited to commercial temperature range (-55°C to +150°C not guaranteed); higher impedance reduces regulation fidelity | Acceptable for cost-sensitive consumer electronics where long-term stability and automotive stress testing are not required |
Compared with MMBZ5223BS-7-F and BZX84-C2V7, BZT52C2V7-13-F provides superior thermal robustness (370 mW vs. ≤350 mW), tighter impedance (100 Ω vs. ≥120 Ω), and AEC-Q101 validation-making it the preferred choice for automotive and industrial designs demanding field reliability and stable reference performance.

FAQ
What is the maximum reverse current at 1.0 V for BZT52C2V7-13-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 confirms low leakage in standby mode, critical for battery-operated systems where quiescent current must remain below 100 µA.
Is BZT52C2V7-13-F suitable for automotive applications?
Yes-BZT52C2V7-13-F is qualified to AEC-Q101 standards and rated for operating temperatures from -65°C to +150°C. Its SOD123 package, lead-free plating, and green molding compound meet automotive electronics requirements for under-hood and cabin modules.
How does the -13-F suffix affect packaging and ordering?
The "-13-F" suffix indicates commercial-grade qualification, SOD123 package, and 10,000-unit tape-and-reel packaging. The "F" denotes lead-free and RoHS-compliant finish; "13" specifies the reel size and orientation per Diodes' ordering convention.
What is the thermal resistance from junction to ambient for this device?
RθJA is 338 °C/W when mounted on an FR-4 PCB with a 1-inch copper pad layout, per Note 8 in the datasheet. This value governs derating curves-e.g., usable power drops to ~250 mW at +75°C ambient-and informs heatsinking decisions in compact enclosures.
