Product details
Overview
HZ16-1LTD-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage reference and stabilization in precision analog circuits, featuring a nominal zener voltage of 15.6 V (min 15.3 V, max 15.9 V), dynamic resistance of 14.0 Ω at 1 mA, maximum power dissipation of 400 mW, and low leakage current ≤1 μA at 12.5 V. It is used in stabilized power supplies, sensor excitation circuits, and ADC reference buffers where noise-sensitive regulation is required.
For engineers reviewing the HZ16-1LTD-E datasheet, HZ16-1LTD-E pinout, HZ16-1LTD-E application, or HZ16-1LTD-E equivalent, key selection criteria include zener voltage tolerance (±2.0%), temperature coefficient (−0.04 %/°C typical at 15.6 V), junction temperature limit (175°C), DO-35 package compatibility, and noise performance critical for metrology-grade references.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a silicon planar junction structure. Its low-noise design achieves approximately 1/3–1/10 the noise level of standard HZ-series Zeners, enabled by optimized doping profile and passivation.
It exhibits a negative temperature coefficient near −0.04 %/°C at 15.6 V, confirming operation in the avalanche-dominated region. The 14.0 Ω dynamic impedance at 1 mA ensures stable regulation under moderate load variations, while the 400 mW power rating supports continuous DC operation within thermal limits on standard FR-4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3 V to 15.9 V at IZ = 0.5 mA - defines tight 2.0% tolerance band for precision reference use |
| Dynamic Resistance (rd) | 14.0 Ω at IZ = 1 mA - ensures minimal output voltage shift under load current changes |
| Reverse Leakage Current (IR) | ≤1 μA at VR = 12.5 V - enables ultra-low standby power in battery-backed reference circuits |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports robust operation without forced cooling in compact designs |
| Junction Temperature (Tj) | −55°C to +175°C - allows deployment in industrial environments with wide ambient swings |
| Noise Level | ≈1/3–1/10 of standard HZ series - directly reduces RMS noise in high-resolution data acquisition front-ends |
Pinout & Package
Package: DO-35 (JEITA code GRZZ0002ZB-A, Renesas code SC-40), glass axial leaded case with navy blue cathode band; body color orange; mass 0.13 g; dimensions: φD = 2.0 mm, E = 4.2 mm, L = 26.0 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-potential terminal during reverse bias | Connected to regulated positive rail; polarity marking essential for correct orientation in shunt regulator topology |
| 2 (Anode) | Low-potential terminal during reverse bias | Typically tied to ground or common reference node; forms return path for zener current |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise performance | Reduces broadband RMS noise in voltage references by up to 90% vs. legacy HZ series, critical for 16-bit+ ADC stability |
| Low dynamic impedance | 14.0 Ω enables <1 mV output variation per 100 μA load change-ideal for driving op-amp inputs or DAC references |
| Tight zener voltage tolerance | ±2.0% (15.3–15.9 V) eliminates need for post-assembly trimming in production test flows |
| High junction temperature rating | 175°C maximum allows reliable operation in sealed enclosures or near heat-generating components |
| Low leakage current | ≤1 μA at 12.5 V minimizes error contribution in high-impedance bias networks and battery-powered sensors |
Applications
| Industrial Sensor Signal Conditioning | Precision Data Acquisition Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5245B | Zener voltage 15 V ±5%, rd = 17 Ω, noise not specified, SOD-123 package | Higher voltage tolerance and no published noise spec limit use in metrology-grade systems | Select when cost sensitivity outweighs noise and tolerance requirements; requires PCB footprint redesign |

FAQ
What is the zener voltage tolerance of HZ16-1LTD-E?
The HZ16-1LTD-E has a zener voltage range of 15.3 V to 15.9 V at 0.5 mA test current, corresponding to a ±2.0% tolerance. This tight specification is confirmed in the Renesas REJ03G0182-0300 datasheet, Page 3, and enables direct use in precision reference designs without post-production trimming. The HZ16-1LTD-E achieves this via controlled avalanche breakdown in its silicon planar junction.
Does HZ16-1LTD-E have a documented noise specification?
Yes-the HZ16-1LTD-E datasheet explicitly states its noise level is "approximately 1/3–1/10 lower than the HZ series," verified through comparative spectral analysis in Renesas' characterization lab. This low-noise performance is intrinsic to the HZ-L Series' optimized doping and passivation process, making HZ16-1LTD-E suitable for 16-bit+ data acquisition systems where reference noise dominates total error budget.
What is the maximum power dissipation rating for HZ16-1LTD-E?
The HZ16-1LTD-E is rated for 400 mW maximum power dissipation at 25°C ambient temperature, as specified in the Absolute Maximum Ratings table (Page 2 of REJ03G0182-0300). Derating is required above 25°C per the published curve in Figure 3, reaching ~200 mW at 75°C ambient. This rating supports continuous DC operation in standard FR-4 PCB layouts with 10 mm lead length.
Is HZ16-1LTD-E compatible with DO-35 socket footprints?
Yes-HZ16-1LTD-E uses the standard DO-35 package (JEITA code GRZZ0002ZB-A, Renesas code SC-40), with 2.0 mm diameter body, 4.2 mm lead spacing (E), and 26.0 mm overall length. Its navy blue cathode band and orange body match JEDEC DO-35 mechanical specifications, ensuring full compatibility with existing DO-35 sockets, wave solder pallets, and automated placement feeders.
What is the temperature coefficient of HZ16-1LTD-E?
The HZ16-1LTD-E exhibits a zener voltage temperature coefficient (γZ) of approximately −0.04 %/°C at 15.6 V, as shown in Figure 2 of the REJ03G0182-0300 datasheet. This negative coefficient reflects avalanche-dominated breakdown behavior and provides predictable, linear drift over temperature-enabling compensation in high-accuracy analog systems where reference stability across −40°C to +125°C is required.
