Taiwan Semiconductor Corporation TSZU52C11 RGG

Overview

TSZU52C11 RGG from Taiwan Semiconductor is a 150 mW, 10.45–11.55 V Zener diode in a 0603 surface-mount package, designed for precision voltage regulation and reference functions in space-constrained PCBs. It features 20 Ω dynamic impedance at 5 mA test current, 0.1 µA leakage at 8.5 V reverse bias, and operates across –55°C to +125°C junction temperature.

For engineers reviewing the TSZU52C11 RGG datasheet, TSZU52C11 RGG pinout, TSZU52C11 RGG application, or TSZU52C11 RGG equivalent, key selection criteria include zener voltage tolerance (±5%), low leakage at rated VR, thermal stability in compact layouts, and compatibility with automated 0603 placement and reflow processes.

Technical Context

This device implements a single-die silicon Zener structure optimized for stable reverse-breakdown operation at nominal 11 V. Its 0603 footprint enables integration into high-density power management and signal conditioning circuits where board area is constrained.

Electrical behavior is defined by tight V_Z tolerance (±5% at I_Z = 5 mA), low dynamic impedance (20 Ω max), and controlled temperature coefficient - critical for maintaining regulation accuracy under varying thermal loads and input conditions.

FAQ

What is the zener voltage tolerance of TSZU52C11 RGG?

The TSZU52C11 RGG has a zener voltage range of 10.45 V to 11.55 V at I_Z = 5 mA, corresponding to a ±5% tolerance. This specification is verified per Taiwan Semiconductor's G2009 datasheet and applies strictly under standard test conditions (T_A = 25°C). The tolerance remains stable across its –55°C to +125°C operating junction temperature range, making TSZU52C11 RGG suitable for precision reference applications where thermal drift must be minimized.

Does TSZU52C11 RGG support automated SMT assembly?

Yes, TSZU52C11 RGG is qualified for standard surface-mount technology processes. Its 0603 package (1.6 × 0.8 mm) and gold-plated terminals meet MIL-STD-750 Method 2026 solderability requirements. The component is supplied on 7-inch reels with 4,000 units per reel, enabling compatibility with high-speed pick-and-place equipment and lead-free reflow profiles up to 260°C peak temperature. TSZU52C11 RGG's cathode band marking also supports optical recognition during placement verification.

What is the maximum leakage current for TSZU52C11 RGG?

The maximum leakage current for TSZU52C11 RGG is 0.1 µA at V_R = 8.5 V and T_A = 25°C, as specified in the Electrical Specifications table of the official datasheet. This low leakage value is critical for battery-powered systems and high-impedance reference nodes. Leakage remains below 1 µA up to 10 V reverse bias, ensuring minimal parasitic loading in precision analog circuits using TSZU52C11 RGG as a voltage clamp or reference source.

Can TSZU52C11 RGG be used in automotive under-hood applications?

Yes, TSZU52C11 RGG is rated for junction temperatures from –55°C to +125°C and is constructed in a thermally robust 0603 package with gold-plated terminations. Its specified electrical parameters - including V_Z, Z_ZT, and I_R - are guaranteed across this full range. These characteristics make TSZU52C11 RGG appropriate for non-safety-critical automotive under-hood functions such as sensor biasing, ECU power rail supervision, and LIN bus voltage referencing, provided derating per Fig.7 (Steady State Power Derating) is applied.

How does the dynamic impedance of TSZU52C11 RGG affect regulation stability?

TSZU52C11 RGG exhibits a maximum dynamic impedance (Z_ZT) of 20 Ω at I_Z = 5 mA, which directly determines how tightly it maintains output voltage under varying load current. Lower Z_ZT yields smaller ΔV_OUT for a given ΔI_LOAD, improving regulation accuracy in shunt configurations. This 20 Ω value enables stable 11 V reference generation in low-noise analog signal chains and feedback loops where TSZU52C11 RGG serves as the primary voltage-setting element.
