Product details
Overview
BZT52C13-G from Taiwan Semiconductor is a 13 V ±5% tolerance surface-mount Zener diode in SOD-123 package, rated for 350 mW power dissipation, 30 Ω dynamic impedance at 5 mA test current, and operating junction temperature up to +150°C. It provides precise voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the BZT52C13-G datasheet, BZT52C13-G pinout, BZT52C13-G application, or BZT52C13-G equivalent, key selection criteria include nominal Zener voltage (13 V), tight 5% tolerance, low leakage current (≤0.1 µA at 8.0 V), thermal stability (7.0 mV/°C tempco), and SOD-123 footprint compatibility with automated PCB assembly.
Technical Context
The BZT52C13-G operates as a single-die, cathode-banded Zener diode optimized for stable reverse-breakdown regulation. Its 13 V nominal Zener voltage is specified at 5 mA test current (IZT), with dynamic impedance (ZZT) of 30 Ω and knee impedance (ZZK) of 170 Ω at 1 mA, ensuring predictable clamping behavior across load transients.
Designed for ambient temperatures from –55°C to +150°C, it features a junction-to-ambient thermal resistance of 357°C/W and meets JESD201 Class 1A whisker resistance, supporting reliable operation in industrial control and automotive body electronics where thermal cycling and long-term stability are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5242B-7-F | 13 V nominal, ±5%, 350 mW, SOT-23 package, 30 Ω ZZT, but higher leakage (≤1 µA at 8 V) | Same regulation function but larger SOT-23 footprint; less suitable for ultra-high-impedance bias networks | Select when SOT-23 is already standardized in design and slightly higher leakage is acceptable |
| 1N4742A | 12 V nominal, ±5%, 1 W, DO-41 through-hole package, 9 Ω ZZT, but no RoHS/halogen-free compliance | Higher power rating but incompatible with SMT-only production; unsuitable for space-constrained PCBs | Choose only for legacy through-hole designs requiring >350 mW dissipation and no environmental compliance mandates |
Compared with MMBZ5242B-7-F and 1N4742A, the BZT52C13-G offers optimal balance of SOD-123 compactness, 0.1 µA ultra-low leakage, and full RoHS/halogen-free compliance-making it preferred for modern industrial and automotive SMT designs where board area, power efficiency, and regulatory alignment are jointly critical.

FAQ
What is the nominal Zener voltage and tolerance of the BZT52C13-G?
The BZT52C13-G has a nominal Zener voltage of 13 V with a guaranteed tolerance of ±5%, meaning its actual breakdown voltage falls between 12.4 V and 14.1 V when tested at 5 mA (IZT). This tight tolerance enables accurate voltage referencing without external calibration, and the specification is validated per Taiwan Semiconductor's C2007 datasheet revision.
What package type does the BZT52C13-G use, and is it compatible with standard reflow profiles?
The BZT52C13-G uses the SOD-123 surface-mount package with matte tin-plated leads compliant with J-STD-002 solderability standards. It is rated at moisture sensitivity level 1 per J-STD-020, meaning it can be placed directly onto PCBs without baking-even after extended storage-making it fully compatible with standard lead-free reflow profiles used in high-volume SMT lines.
What is the maximum power dissipation and thermal resistance of the BZT52C13-G?
The BZT52C13-G has a maximum power dissipation (PD) of 350 mW at 25°C ambient, derating linearly above that temperature. Its junction-to-ambient thermal resistance (RθJA) is 357°C/W, meaning each watt of dissipated power raises the junction temperature by 357°C above ambient-critical for thermal design in enclosed or high-temperature environments like automotive BCMs.
How does the leakage current of the BZT52C13-G compare to other 13 V Zener diodes?
The BZT52C13-G exhibits exceptionally low leakage current: ≤0.1 µA at 8.0 V reverse bias (VR), significantly lower than alternatives like MMBZ5242B-7-F (≤1 µA). This ultra-low leakage preserves signal integrity in high-impedance analog circuits and extends battery life in always-on IoT nodes-directly confirmed in Taiwan Semiconductor's C2007 datasheet electrical specifications table.
Is the BZT52C13-G RoHS and halogen-free compliant?
Yes, the BZT52C13-G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and all plating and materials are certified to meet global environmental directives-making it suitable for export to EU, China, and other regulated markets without compliance risk.
