Product details

Overview

TSZU52C5V6 from Taiwan Semiconductor is a surface-mount 5.6 V ±5% zener diode in 0603 package, rated for 150 mW power dissipation, 5 mA test current, and 40 Ω dynamic impedance at 5 mA, used for precision voltage regulation in low-power analog circuits and reference biasing.

For engineers reviewing the TSZU52C5V6 datasheet, TSZU52C5V6 pinout, TSZU52C5V6 application, or TSZU52C5V6 equivalent, key selection criteria include zener voltage tolerance (±5%), low dynamic impedance (40 Ω), leakage current (0.1 µA @ 1.0 V), and RoHS/halogen-free compliance in ultra-thin 0603 footprint.

Technical Context

This device operates as a single-die, cathode-banded zener diode with reverse-breakdown regulation. It maintains stable 5.6 V reference under 5 mA test current, exhibits 40 Ω dynamic impedance at I_ZT, and supports junction temperatures from –55°C to +125°C.

Its 0603 package uses gold-plated terminals compliant with MIL-STD-750 Method 2026, enabling reflow soldering on compact PCBs. Leakage current is specified at 0.1 µA when reverse-biased at 1.0 V, confirming tight low-voltage blocking performance.

Pinout & Package

TSZU52C5V6 is a two-terminal surface-mount zener diode in JEDEC-standard 0603 package. Polarity is marked by a cathode band on the component body; terminal 1 (anode) and terminal 2 (cathode) are defined by orientation relative to this band.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX584-C5V6 (Nexperia)	Same 5.6 V ±5%, 150 mW, 0603 package; 50 Ω Z_ZT vs. TSZU52C5V6's 40 Ω	Slightly higher dynamic impedance may reduce regulation tightness in high-precision feedback	Preferred where Nexperia supply chain alignment or AEC-Q200 qualification is required
MMBZ5232BS (ON Semiconductor)	5.6 V ±5%, 200 mW rating, SOT-323 package (larger than 0603); 30 Ω Z_ZT	Higher power rating but incompatible 3-pin SOT-323 footprint requires PCB redesign	Selected when thermal margin >150 mW is needed and board space permits larger package

Compared with BZX584-C5V6 and MMBZ5232BS, TSZU52C5V6 offers the lowest dynamic impedance (40 Ω) in the smallest standard 0603 footprint, making it optimal for space-constrained, low-drift voltage reference designs where 150 mW suffices.

FAQ

What is the zener voltage tolerance of TSZU52C5V6?

The TSZU52C5V6 has a zener voltage range of 5.32 V to 5.88 V at 5 mA test current, corresponding to a ±5% tolerance about the nominal 5.6 V rating. This tolerance is verified per the Electrical Specifications table in the official TSC datasheet Version G2009 and applies under standard test conditions (T_A = 25°C).

What is the maximum power dissipation for TSZU52C5V6?

The TSZU52C5V6 is rated for 150 mW maximum power dissipation at 25°C ambient temperature. Derating is required above 25°C per the Steady State Power Derating curve (Fig.7), reaching zero dissipation at 125°C junction temperature. The 0603 package limits thermal capacity, so design must ensure adequate PCB copper area or airflow.

Does TSZU52C5V6 have RoHS and halogen-free certification?

Yes, TSZU52C5V6 is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the TSC datasheet. The device uses gold-plated terminals and lead-free solder-compatible construction, meeting environmental requirements for consumer and industrial end equipment.

What is the dynamic impedance of TSZU52C5V6 and why does it matter?

The dynamic impedance (Z_ZT) of TSZU52C5V6 is 40 Ω at 5 mA test current. This value quantifies how much the zener voltage changes with small variations in current - lower Z_ZT means tighter regulation. In practice, it directly impacts stability in feedback loops and reference accuracy under dynamic load conditions.

How is polarity indicated on the TSZU52C5V6 package?

Polarity on TSZU52C5V6 is indicated by a visible cathode band printed on the component body. When mounted on PCB with the band aligned toward the designated cathode pad, the terminal adjacent to the band is the cathode; the opposite terminal is the anode. This marking conforms to JEDEC 0603 orientation standards and is confirmed in the MECHANICAL DATA section.
