Renesas HZU13B1JTRF

Overview

HZU13B1JTRF from Renesas Electronics is a silicon planar Zener diode designed for voltage stabilization in low-power analog and reference circuits, with a nominal Zener voltage of 13.5 V (min 13.84 V, max 14.46 V at I_Z = 5 mA), 2 mW reverse current limit at V_R = 10 V, and dynamic resistance of 10 Ω - suitable for precision biasing in sensor signal conditioning and power supply feedback loops.

For engineers reviewing the HZU13B1JTRF datasheet, HZU13B1JTRF pinout, HZU13B1JTRF application, or HZU13B1JTRF equivalent, key selection criteria include its URP (SC-76A) surface-mount package, 200 mW power dissipation, ±5% Zener voltage tolerance (Grade B1), junction temperature rating up to 150°C, and compatibility with automated SMT assembly on space-constrained PCBs.

Technical Context

The HZU13B1JTRF operates as a two-terminal voltage reference device using silicon planar Zener breakdown at reverse bias. Its electrical behavior is defined under pulsed test conditions (PW = 40 ms) to minimize self-heating, with specified parameters valid at T_a = 25°C and derated linearly above 25°C per Fig.3.

It exhibits a negative Zener voltage temperature coefficient (γ_Z) near –0.02%/°C (≈ –2.7 mV/°C) per Fig.2, indicating stable regulation over temperature when used within its 2 mA to 5 mA operating current range and ambient limits of –55°C to +150°C.

FAQ

What is the Zener voltage tolerance of HZU13B1JTRF?

The HZU13B1JTRF has a Grade B1 Zener voltage specification of 13.84 V minimum to 14.46 V maximum at 5 mA test current, corresponding to a ±2.3% tolerance around the nominal 13.5 V rating. This tighter tolerance than standard Grade B (±5%) is confirmed in the Electrical Characteristics table on page 2 of R07DS0423EJ1000 Rev.10.00 and directly applies to the HZU13B1JTRF part number.

Does HZU13B1JTRF support continuous DC operation?

Yes, HZU13B1JTRF supports continuous DC operation up to its absolute maximum power dissipation of 200 mW at T_a = 25°C, with linear derating above that ambient temperature per Fig.3. Its 150°C maximum junction temperature and –55°C to +150°C storage range make it suitable for sustained biasing in industrial and automotive environments - verified in the Absolute Maximum Ratings table on page 2 of the datasheet.

What is the package type and dimensions of HZU13B1JTRF?

HZU13B1JTRF uses the URP (Ultra small Resin Package), also known as SC-76A, with dimensions of 0.8 mm × 0.8 mm × 0.45 mm max height and a typical mass of 0.004 g. The package code STSP0002ZA-A and JEITA designation URP are explicitly assigned to HZU13B1JTRF in the Ordering Information section and Package Dimensions table on pages 1 and 6 of R07DS0423EJ1000 Rev.10.00.

How does the dynamic resistance of HZU13B1JTRF affect regulation performance?

The HZU13B1JTRF has a maximum dynamic resistance (r_d) of 10 Ω at I_Z = 5 mA, meaning its output voltage changes by ≤10 mV per 1 mA change in Zener current. This low r_d ensures minimal regulation error under varying load or supply conditions - critical for precision feedback and reference applications - and is measured per the test condition specified in the Electrical Characteristics table on page 2.

Is HZU13B1JTRF RoHS compliant and lead-free?

Yes, HZU13B1JTRF is RoHS compliant and lead-free. Renesas Electronics confirms environmental compliance in the "Notice" section on page 6 of R07DS0423EJ1000 Rev.10.00, stating adherence to the EU RoHS Directive and recommending compliance verification via their website. The device carries no lead-based finishes and meets JEDEC J-STD-609 Category 1 marking requirements for lead-free terminations.
