Product details
Overview
BZT52C13 RHG from Taiwan Semiconductor is a surface-mount 13 V ±5% Zener diode in SOD-123F package, rated for 500 mW power dissipation and tested at 5 mA zener current (IZT). It provides precise low-voltage regulation with 30 Ω dynamic impedance (ZZT) and 0.09 µA leakage current at 8.0 V reverse bias, commonly used in DC/DC converter voltage references and adapter stabilization circuits.
For engineers reviewing the BZT52C13 RHG datasheet, BZT52C13 RHG pinout, BZT52C13 RHG application, or BZT52C13 RHG equivalent, key selection criteria include verified 13.0 V nominal zener voltage, SOD-123F thermal resistance (350 °C/W), cathode-band polarity marking, moisture sensitivity level 1 compliance, and RoHS/WEEE/halogen-free certification - all critical for industrial power supply design and board-level reliability validation.
Technical Context
The BZT52C13 RHG operates as a single-die, unidirectional voltage reference device with sharp zener breakdown at 13.0 V (±5%) under 5 mA test current. Its 30 Ω zener impedance at IZT and 160 Ω knee impedance at 1 mA ensure stable regulation across load variations in low-power analog and digital supply rails.
Designed for surface-mount assembly, it features matte tin-plated leads compliant with J-STD-002 solderability, UL 94 V-0 molding compound, and a junction temperature range of –65 °C to +150 °C - enabling reliable operation in automotive-grade ambient environments and thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.35–13.65 V (±5% tolerance at 5 mA; ensures tight regulation window for 12 V rail referencing) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5242B | 13 V ±5%, SOD-123, 500 mW, but higher ZZT = 35 Ω and IR = 0.1 µA @ 8 V | Slightly looser regulation stability; identical thermal and mounting specs | Acceptable where 5 Ω higher impedance does not impact loop stability |
| Vishay NZX13A | 13 V ±5%, DO-35 glass package, 500 mW, but MSL Level 2 and higher RθJA (~450 °C/W) | Requires moisture baking pre-reflow; less suitable for high-density SMT layouts | Preferred only for through-hole prototyping or legacy DO-35 footprint reuse |
Compared with MMBZ5242B and NZX13A, the BZT52C13 RHG delivers superior thermal performance (350 °C/W), lower leakage (0.09 µA), and guaranteed Level 1 moisture handling - making it optimal for high-volume, space-constrained, and thermally demanding SMT production.

FAQ
What is the exact zener voltage tolerance and test condition for BZT52C13 RHG?
The BZT52C13 RHG has a nominal zener voltage of 13.0 V with a guaranteed tolerance of ±5%, meaning the actual VZ falls between 12.35 V and 13.65 V when measured at IZT = 5 mA under pulse conditions (30 ms duration). This tolerance is confirmed in the official Taiwan Semiconductor G1804 datasheet revision and applies strictly to the BZT52C13 RHG variant.
Is BZT52C13 RHG suitable for reflow soldering without moisture preconditioning?
Yes, BZT52C13 RHG is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to standard Pb-free reflow profiles (e.g., JEDEC J-STD-020D) without prior dry-pack storage or baking. The SOD-123F package's hermetic molding and low hygroscopicity eliminate popcorning risk during assembly - a key advantage over MSL 2+ alternatives.
What is the maximum power dissipation of BZT52C13 RHG at 70°C ambient temperature?
At TA = 70 °C, the BZT52C13 RHG's maximum allowable power dissipation is reduced from 500 mW (at 25 °C) to approximately 357 mW, calculated using its thermal resistance RθJA = 350 °C/W: PD(max) = (TJ(max) − TA) / RθJA = (150 − 70) / 350 = 0.229 W. Derating curves in the datasheet confirm this linear relationship.
Does BZT52C13 RHG have halogen-free and RoHS compliance documentation?
Yes, BZT52C13 RHG is certified halogen-free per IEC 61249-2-21 and compliant with RoHS Directive 2011/65/EU and WEEE 2002/96/EC. These declarations are published in Taiwan Semiconductor's material compliance reports and referenced in the G1804 datasheet revision - no exemptions apply, and full substance declarations are available upon request.
How does the leakage current of BZT52C13 RHG compare to other 13 V Zeners in the same family?
The BZT52C13 RHG specifies 0.09 µA leakage current (IR) at VR = 8.0 V, matching the values for BZT52C11, BZT52C12, and BZT52C15 in the same datasheet table. This consistency confirms process uniformity across the 11–15 V segment of the BZT52C family, ensuring predictable low-power behavior in high-impedance reference nodes.
