Product details

Overview

HZU5.6GTRF-E from Renesas Electronics is a silicon planar Zener diode designed for voltage stabilization in low-power analog and digital supply rails, featuring a nominal zener voltage of 5.6 V, 200 mW power dissipation, and ultra-small URP (SC-76A) surface-mount package with cathode/anode pinout. It operates within –55°C to +150°C storage range and supports stabilization in precision reference, overvoltage protection, and biasing circuits.

For engineers reviewing the HZU5.6GTRF-E datasheet, HZU5.6GTRF-E pinout, HZU5.6GTRF-E application, or HZU5.6GTRF-E equivalent, key selection criteria include zener voltage tolerance (±5.4% at 5 mA), dynamic resistance (80 Ω max), reverse current (5 µA max at 2.5 V), junction temperature limit (150°C), and tape-and-reel packaging (3,000 pcs/reel) for automated assembly.

Technical Context

This device functions as a two-terminal voltage reference by operating in reverse breakdown mode with controlled zener characteristics. Its planar silicon construction ensures stable voltage regulation under DC or low-frequency transient conditions, with graded B3 tolerance (5.67–5.92 V) specified at I_Z = 5 mA.

The URP package (SC-76A) enables high-density PCB layout with 0.8 mm body height and 1.5 mm × 0.8 mm footprint. Thermal derating follows Fig.3: power dissipation linearly decreases from 200 mW at 25°C to zero at 150°C ambient, requiring thermal design consideration in enclosed or high-Ta environments.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMSZ5232B-TP (Micro Commercial)	Zener voltage 5.6 V (±5%), P_d = 500 mW, SOD-123 package (2.7 × 1.6 mm).	Larger footprint and higher power rating suit higher-current regulation but require more board area.	Select when >200 mW dissipation or legacy SOD-123 layout compatibility is required.
BZX584-C5V6 (Nexperia)	Zener voltage 5.6 V (±5%), P_d = 300 mW, SOD-323 package (1.7 × 1.3 mm), 90 Ω r_d.	Slightly larger footprint than URP and higher dynamic resistance reduce regulation precision in low-current references.	Choose for cost-sensitive designs where 90 Ω r_d and 300 mW rating meet system margin requirements.

Compared with MMSZ5232B-TP and BZX584-C5V6, the HZU5.6GTRF-E offers the smallest PCB footprint (1.5 × 0.8 mm), lowest profile (0.8 mm), and tightest voltage tolerance (±4.5%) among these three, making it optimal for miniaturized, high-accuracy voltage reference designs where space and regulation stability are critical.

FAQ

What is the zener voltage tolerance of HZU5.6GTRF-E?

The HZU5.6GTRF-E has a zener voltage range of 5.67 V to 5.92 V at I_Z = 5 mA, corresponding to ±4.5% tolerance (B3 grade). This tighter specification improves regulation accuracy compared to standard B-grade Zeners and supports precise reference applications where voltage drift must be minimized.

Does HZU5.6GTRF-E support reflow soldering?

Yes, the HZU5.6GTRF-E uses the URP (SC-76A) package qualified for standard lead-free reflow profiles per JEDEC J-STD-020. Its 0.8 mm height and thermally robust silicon planar structure withstand peak temperatures up to 260°C, ensuring reliable solder joint formation without parametric shift or mechanical damage.

What is the maximum reverse current for HZU5.6GTRF-E at 2.5 V?

The maximum reverse current (I_R) for HZU5.6GTRF-E is 5 µA at V_R = 2.5 V and T_a = 25°C. This low leakage supports ultra-low-power applications such as battery-backed sensors and always-on monitoring circuits where standby current must remain below 10 µA.

Can HZU5.6GTRF-E replace a 5.1 V Zener diode in an existing design?

No - the HZU5.6GTRF-E is rated for 5.67–5.92 V, not 5.1 V. Substituting it for a 5.1 V part (e.g., HZU5.1) would raise the regulated voltage by ~10%, potentially causing overvoltage stress on downstream ICs. Always verify target voltage match and dynamic resistance compatibility before replacement.

Is HZU5.6GTRF-E RoHS compliant and halogen-free?

Yes, HZU5.6GTRF-E complies with EU RoHS Directive 2011/65/EU and is halogen-free per Renesas' material declarations. The URP package uses lead-free terminations and environmentally compliant molding compounds, meeting IPC-1752A reporting standards for restricted substances.
