Product details
Overview
BZT52C5V1-13 from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 5.1 V, ±5% tolerance (4.8–5.4 V), 500 mW power dissipation at TL = +75°C, 60 Ω maximum zener impedance at 5 mA, and −2.7 mV/°C temperature coefficient. It serves as a precision voltage reference or overvoltage clamp in low-power analog and digital supply rails.
For engineers reviewing the BZT52C5V1-13 datasheet, BZT52C5V1-13 pinout, BZT52C5V1-13 application, or BZT52C5V1-13 equivalent, key selection criteria include zener voltage stability under varying temperature, low dynamic impedance for regulation accuracy, SOD123 package compatibility with high-density PCB layouts, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals. Its planar die construction ensures consistent electrical performance and thermal stability, while the −2.7 mV/°C temperature coefficient enables predictable drift compensation in bias networks.
The device delivers 5.1 V regulation at 5 mA test current with 60 Ω dynamic impedance, supporting accurate voltage clamping in signal conditioning, power supply feedback loops, and ESD protection circuits where tight voltage tolerance and low leakage (<2 µA at 3.7 V) are required.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5221BS-7-F | Zener voltage 3.3 V, 300 mW PD, SOT-23 package | Lower voltage and power rating; smaller footprint but higher thermal resistance | Select when space-constrained layout requires SOT-23 and 3.3 V regulation suffices |

FAQ
What is the maximum continuous reverse voltage (VRWM) for BZT52C5V1-13?
The BZT52C5V1-13 does not specify a rated VRWM; instead, its rated reverse voltage is defined by the test condition VR = 3.7 V, at which reverse current is guaranteed ≤2.0 µA. Operation above 5.4 V enters breakdown region and must be current-limited to avoid exceeding 500 mW dissipation.
Can BZT52C5V1-13 be used in parallel for higher power handling?
No-Zener diodes exhibit manufacturing variations in breakdown voltage, causing current imbalance when paralleled. Even matched units risk thermal runaway due to negative temperature coefficient. For higher power, use a single higher-rated Zener or a dedicated voltage regulator IC.
Is the SOD123 package compatible with standard reflow profiles?
Yes-the SOD123 package is qualified for lead-free reflow per JEDEC J-STD-020, with Moisture Sensitivity Level 1. Standard IPC/JEDEC profiles (peak 260°C, 60–90 sec above 217°C) are fully supported without preconditioning.
Does BZT52C5V1-13 meet automotive requirements?
Yes-BZT52C5V1-13 is explicitly qualified to AEC-Q101 standards, including stress tests for high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing (uHAST), making it suitable for under-hood and infotainment applications.
