Product details
Overview
HZU15B2JTRF from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for hard-knee, low-noise voltage reference applications. It delivers a nominal Zener voltage of 15 V at 0.5 mA, with dynamic resistance of 380 Ω (typ), temperature coefficient of −1.5 mV/°C, and ultra-low noise voltage-approximately 1/3 to 1/10 that of standard HZU-series diodes. It is used in precision analog front-ends and low-drift reference circuits.
For engineers reviewing the HZU15B2JTRF datasheet, HZU15B2JTRF pinout, HZU15B2JTRF application, or HZU15B2JTRF equivalent, key selection criteria include its hard-knee Vz–Iz linearity (1 nA to 1 mA), ultra-small URP package (SC-76A), low thermal drift, and suitability for noise-sensitive voltage regulation and calibration references.
Technical Context
The HZU15B2JTRF operates as a two-terminal, DC-biased Zener reference with semi-logarithmic linear Vz–Iz characteristics across an exceptionally wide reverse current range (1 nA to 1 mA). Its hard-knee behavior ensures stable regulation onset without soft turn-on ambiguity.
Designed for surface-mount use, it leverages Renesas' URP (Ultra small Resin Package) with SC-76A footprint and JEITA code PTSP0002ZA-A. The device exhibits a junction temperature limit of 150°C and maximum power dissipation of 150 mW at 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.9 V (min) to 15.3 V (max) at IZ = 0.5 mA - defines tight regulation band for precision references |
| Dynamic Resistance (ZZT) | 380 Ω (typ) at IZT = 0.5 mA - low impedance ensures minimal output perturbation under load transients |
| Temperature Coefficient (γZ) | −1.5 mV/°C (typ) - half that of legacy HZU series, enabling improved thermal stability |
| Reverse Current (IR) | ≤100 nA at VR = 12 V - supports ultra-low leakage bias networks |
| Noise Voltage | ≈1/3 to 1/10 lower than HZU series - critical for high-resolution ADC/DAC reference buffering |
| Power Dissipation (Pd) | 150 mW (max) at Ta = 25°C - constrains usable current in compact PCB layouts |
| Junction Temperature (Tj) | 150°C (max) - sets thermal derating boundary for sustained operation |
Pinout & Package
Package: Ultra small Resin Package (URP), SC-76A footprint per JEITA code PTSP0002ZA-A; dimensions 1.55 × 0.80 × 0.45 mm (L × W × H); mass ≈ 0.004 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity mark on package surface identifies this terminal |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Hard-knee Zener characteristic | VZ–IZ curve remains semi-logarithmically linear from 1 nA to 1 mA - eliminates ambiguity in regulation threshold definition |
| Low-noise voltage generation | Reduction to 10–33% of standard HZU-series noise - directly improves SNR in precision measurement signal chains |
| Reduced temperature coefficient | γZ ≈ −1.5 mV/°C (typ), ~50% lower than HZU series - lowers drift-induced error in wide-temperature-range instruments |
| Surface-mount ultra-miniature package | SC-76A (URP) footprint enables high-density layout in space-constrained analog modules and portable test equipment |
| Stable low-current regulation | Validated operation down to 1 nA reverse current - supports micropower biasing and battery-operated reference designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15LT1G | Zener voltage tolerance ±5%; TC ≈ −2.5 mV/°C; noise not specified; SOT-23 package (larger than URP) | General-purpose regulation where tighter TC and noise specs are non-critical | Select when cost sensitivity outweighs precision requirements and board area permits SOT-23 |
| MMSZ5245B-TP | 15 V nominal, ±5% tolerance; TC ≈ −2.0 mV/°C; no published noise data; SOD-123 package | Consumer-grade power rails and basic voltage clamping | Choose for high-volume, non-precision applications where URP size and low-noise performance are unnecessary |
Compared with BZX84-C15LT1G and MMSZ5245B-TP, the HZU15B2JTRF provides superior thermal stability (−1.5 mV/°C), quantified low-noise performance, and a 40% smaller footprint-making it uniquely suited for miniaturized, high-accuracy analog subsystems where drift and spectral purity are design-critical.

FAQ
What is the Zener voltage tolerance of the HZU15B2JTRF at 0.5 mA?
The HZU15B2JTRF has a Zener voltage range of 14.9 V (minimum) to 15.3 V (maximum) at IZ = 0.5 mA, corresponding to ±1.3% tolerance about the nominal 15 V rating. This tight tolerance is confirmed in the Electrical Characteristics table of Renesas document REJ03G1216-0500 Rev.5.00 and applies specifically to the HZU15B2JTRF variant within the HZU-LL family.
Does the HZU15B2JTRF support operation below 1 µA reverse current?
Yes, the HZU15B2JTRF maintains semi-logarithmic linear VZ–IZ characteristics down to 1 nA, as explicitly stated in the Features section of the datasheet. This enables reliable use in micropower bias networks and energy-harvesting circuits where current is constrained to nanoampere levels-distinct from conventional Zeners that degrade below 10 µA.
What is the package type and JEITA code for the HZU15B2JTRF?
The HZU15B2JTRF uses the Ultra small Resin Package (URP), also known as SC-76A, with JEITA package code PTSP0002ZA-A. Its physical dimensions are 1.55 mm × 0.80 mm × 0.45 mm, and it weighs approximately 0.004 g-verified in the Package Dimensions table on page 4 of REJ03G1216-0500 Rev.5.00.
How does the noise performance of the HZU15B2JTRF compare to standard Zener diodes?
The HZU15B2JTRF delivers approximately 1/3 to 1/10 the noise voltage of standard HZU-series Zeners, as stated in the Features section of the datasheet. This quantified improvement is achieved through epitaxial planar process optimization and is critical for preserving signal integrity in high-resolution data converters and low-level analog measurement paths where HZU15B2JTRF serves as the primary reference source.
Is the HZU15B2JTRF rated for automotive or safety-critical applications?
No, the HZU15B2JTRF is classified as a Standard-grade Renesas product intended for industrial, test equipment, and consumer applications-not for automotive, aerospace, medical life-support, or other safety-critical systems. This is confirmed in the Colophon and Notice sections of REJ03G1216-0500 Rev.5.00, which explicitly restrict such use without prior written consent from Renesas Electronics.
