Product details
Overview
BZT52C16-13-F from Diodes Incorporated is a surface-mount 16 V Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C and 370 mW at TA = +25°C, with ±5% zener voltage tolerance (15.3–17.1 V), 40 Ω maximum zener impedance at 5 mA, and 0.1 µA maximum reverse leakage at 12.8 V. It serves as a precision voltage reference or overvoltage clamp in low-power DC supply rails and signal conditioning circuits.
For engineers reviewing the BZT52C16-13-F datasheet, BZT52C16-13-F pinout, BZT52C16-13-F application, or BZT52C16-13-F equivalent, key selection criteria include zener voltage accuracy, thermal resistance (RθJA = 338 °C/W), cathode-band polarity marking, SOD123 footprint compatibility, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under controlled current conditions. Its planar die construction ensures consistent breakdown characteristics, while the SOD123 package supports automated pick-and-place assembly and provides defined thermal performance on FR-4 PCBs with 1-inch copper pad layout.
The device exhibits a positive temperature coefficient of +11.2 mV/°C near 16 V, enabling predictable drift compensation in temperature-sensitive references. Reverse leakage remains ≤0.1 µA at VR = 12.8 V, supporting low-quiescent-current designs where standby power is critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5245B-7-F | Zener voltage 16 V, but ±5% tolerance only at 20 mA test current; RθJA = 350 °C/W; SOD123 package | Higher test current shifts operating point-less suitable for low-current bias networks | Select when higher power handling at elevated ambient is prioritized over low-Iz stability |
| BZX84-C16 | SOT-23 package; 16 V nominal, ±5% at 5 mA; 350 mW max power; RθJA = 300 °C/W | Smaller footprint but higher thermal resistance limits sustained power in compact layouts | Prefer for space-constrained PCBs where thermal margin allows reduced copper area |
Compared with MMSZ5245B-7-F and BZX84-C16, BZT52C16-13-F offers tighter low-current regulation (5 mA test point), superior AEC-Q101 qualification, and optimized thermal performance on standard FR-4-making it ideal for automotive and industrial applications demanding reliability at moderate power levels.

FAQ
What is the maximum reverse voltage (VR) at which BZT52C16-13-F guarantees IR ≤ 0.1 µA?
The datasheet specifies 0.1 µA maximum reverse leakage current at VR = 12.8 V. This value is measured under standard test conditions (TA = +25°C) and defines the upper limit of applied reverse bias before leakage rises significantly-critical for low-power bias networks where leakage must remain below 100 nA.
Can BZT52C16-13-F be used in place of a 15 V Zener diode in a voltage reference circuit?
No-its nominal zener voltage is 16.0 V with a guaranteed range of 15.3–17.1 V, making it unsuitable as a direct replacement for a 15 V part like BZT52C15. Substituting would shift reference level by ≥0.3 V, potentially violating system accuracy requirements in precision analog circuits.
Is the SOD123 package of BZT52C16-13-F compatible with standard reflow profiles for lead-free soldering?
Yes-the device uses matte tin-plated leads and is rated for moisture sensitivity Level 1 per J-STD-020, meaning it can be subjected directly to standard Pb-free reflow profiles (e.g., JEDEC J-STD-020 Class 3) without pre-baking or special handling.
Does BZT52C16-13-F have a specified capacitance value relevant for high-frequency noise suppression?
No-capacitance is not characterized in the datasheet for this part. Figure 5 shows typical total capacitance vs. nominal zener voltage, but no discrete value is given for 16 V. For RF filtering applications, a dedicated TVS or capacitor-coupled Zener network is recommended instead.
