Product details

Overview

TSZU52C6V2 from Taiwan Semiconductor is a surface-mount silicon Zener diode with nominal zener voltage 6.2 V (min 5.89 V, max 6.51 V), 150 mW power dissipation, 10 Ω dynamic impedance at 5 mA test current, and operating junction temperature range of −55 °C to +125 °C. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.

For engineers reviewing the TSZU52C6V2 datasheet, TSZU52C6V2 pinout, TSZU52C6V2 application, or TSZU52C6V2 equivalent, key selection criteria include zener voltage tolerance (±5%), low dynamic impedance for stable regulation under varying load, RoHS- and halogen-free compliance, and 0603 package suitability for high-density PCB layouts.

Technical Context

The TSZU52C6V2 operates as a single-die, cathode-banded Zener diode optimized for reverse-bias voltage regulation. Its electrical behavior is defined at 5 mA test current (IZ), with specified rising operating resistance (10 Ω) and leakage current ≤0.1 µA at 2.0 V reverse bias.

It features gold-plated terminals compatible with MIL-STD-750 Method 2026 soldering, a 3.00 mg mass, and thermal derating beginning at 25 °C ambient-full 150 mW rating applies only up to 75 °C ambient, decreasing linearly to zero at 125 °C junction temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX584C6V2	Same 6.2 V nominal zener voltage, but 300 mW P_D, 15 Ω Z_ZT, SOD-523 package (1.2 × 0.8 mm)	Larger footprint and higher power capability; less suitable for ultra-dense 0603-only layouts	Select when higher surge tolerance or thermal margin is required beyond 150 mW limits
MMBZ5234BS	6.2 V zener, 200 mW P_D, 12 Ω Z_ZT, SOT-323 package (2.2 × 1.35 mm)	Three-terminal SOT-323 offers dual-diode configuration; not a direct single-diode replacement	Choose only if dual-Zener topology or board space permits larger footprint and dual-device integration

Compared with BZX584C6V2 and MMBZ5234BS, the TSZU52C6V2 delivers optimal fit for space-constrained, low-power regulation where strict 0603 footprint adherence and ≤150 mW thermal envelope are mandatory design constraints.

FAQ

What is the exact zener voltage range for TSZU52C6V2?

The TSZU52C6V2 has a guaranteed zener voltage range of 5.89 V to 6.51 V at a test current of 5 mA, representing a ±5% tolerance around the nominal 6.2 V rating. This specification is verified per Taiwan Semiconductor's G2009 datasheet revision and applies under standard 25 °C ambient conditions. The TSZU52C6V2 maintains this voltage stability across its rated junction temperature range of −55 °C to +125 °C, with temperature coefficient data provided in the characteristics curves section.

Is TSZU52C6V2 suitable for use in automotive applications?

The TSZU52C6V2 is not AEC-Q200 qualified and is not recommended for automotive safety-critical or under-hood applications. While its junction temperature range (−55 °C to +125 °C) overlaps with some automotive ambient requirements, Taiwan Semiconductor does not list it in their AEC-Q200-certified portfolio. For automotive use, engineers should select explicitly qualified alternatives such as the TSC AEC-Q200-compliant TZM series. The TSZU52C6V2 remains appropriate for industrial, consumer, and portable electronics where extended temperature operation is needed without formal qualification.

What is the maximum reverse leakage current for TSZU52C6V2?

The maximum reverse leakage current for TSZU52C6V2 is 0.1 µA at a reverse voltage (V_R) of 2.0 V, as specified in the Electrical Specifications table of the G2009 datasheet. This value is measured at 25 °C ambient and reflects the device's ability to maintain high impedance in non-conducting states-critical for low-power bias networks and precision reference applications. Leakage remains below 1 µA up to the rated zener voltage and increases predictably with temperature, as shown in Figure 5 of the datasheet.

Does TSZU52C6V2 have a specified forward voltage?

Yes, the TSZU52C6V2 has a typical forward voltage (V_F) of 0.9 V at a forward current (I_F) of 10 mA, per the Absolute Maximum Ratings table. This parameter is relevant when the device is used in forward conduction mode-for example, as a low-voltage clamp or protection diode in bidirectional signal paths. Forward characteristics are further detailed in Figure 4 (Typical Forward Voltage) of the datasheet, showing V_F variation across temperature and current.

What packaging option is available for TSZU52C6V2?

The TSZU52C6V2 is supplied in 0603 (1608 metric) surface-mount package on 4,000-piece 7-inch reels, identified by ordering code TSZU52C6V2 RGG. The package features gold-plated terminations compliant with MIL-STD-750 Method 2026 for robust solderability, and polarity is marked by a cathode band. No tape-and-reel variants for smaller quantities (e.g., cut tape or sample trays) are documented in the official G2009 datasheet or Taiwan Semiconductor's ordering information.
