Product details
Overview
HZ16-2J-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 15.7–16.5 V, 400 mW power dissipation, 14.0 Ω dynamic resistance at 0.5 mA test current, and DO-35 glass package with navy-blue cathode band. It serves as a stable reference in instrumentation amplifiers and low-drift sensor signal conditioning.
For engineers reviewing the HZ16-2J-E datasheet, HZ16-2J-E pinout, HZ16-2J-E application, or HZ16-2J-E equivalent, key selection criteria include zener voltage tolerance (±0.4 V), temperature coefficient (−0.02 %/°C at ~16 V), low noise performance (1/3–1/10 of standard HZ series), and DO-35 mechanical compatibility in space-constrained PCB layouts.
Technical Context
This device operates as a two-terminal shunt regulator with DC-tested zener characteristics, specified at IZ = 0.5 mA and VR ≤ 2.0 V. Its low leakage current (<1 μA at VR = 2.0 V) and tight VZ tolerance support high-accuracy biasing in op-amp feedback networks and ADC reference buffers.
The HZ16-2J-E exhibits a negative temperature coefficient of −0.02 %/°C near 16 V, confirmed by Figure 2 in REJ03G0182-0300, and maintains stable regulation up to Tj = 175°C, enabling use in industrial ambient environments where thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.7–16.5 V at IZ = 0.5 mA - defines precise regulation point for 16 V reference designs |
| Dynamic Resistance (rd) | 14.0 Ω max at IZ = 0.5 mA - ensures minimal output impedance under small-signal AC load variations |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports continuous operation in compact through-hole layouts without forced cooling |
| Zener Temperature Coefficient | −0.02 %/°C - enables predictable, low-drift behavior across −55°C to +125°C operating range |
| Reverse Leakage Current | ≤1 μA at VR = 2.0 V - minimizes error current in high-impedance reference nodes |
| Junction Temperature (Tj) | 175°C maximum - allows reliable operation in thermally demanding industrial enclosures |
Pinout & Package
Package: DO-35 glass axial package (JEITA code GRZZ0002ZB-A), orange body with navy-blue cathode band, mass 0.13 g, dimensions per SC-40 standard (φD = 2.0 mm, L = 26.0 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener voltage reference terminal | Connected to regulated output node; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Reference ground return path | Completes shunt regulation loop; low-inductance PCB trace recommended for noise-sensitive applications |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener operation | Diode noise level ≈1/3–1/10 that of standard HZ series - critical for audio preamps and precision data acquisition |
| Stable low-impedance regulation | rd = 14.0 Ω max at 0.5 mA - reduces sensitivity to load transients in feedback references |
| Wide VZ tolerance control | ±0.4 V absolute window (15.7–16.5 V) - enables binning for matched reference pairs in differential systems |
| High thermal reliability | Tj rating of 175°C - supports long-term stability in sealed industrial modules without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | VZ = 15 V ±5%, rd = 14 Ω, Pd = 1 W, DO-41 package | Higher power but looser tolerance (±5% vs. ±0.4 V) and higher noise | Select when higher power margin is needed and tighter VZ tolerance is not required |
| BZX84-C16 | VZ = 16 V ±5%, rd = 40 Ω, Pd = 300 mW, SOT-23 package | Surface-mount, higher dynamic resistance, no low-noise specification | Select for automated assembly where DO-35 axial lead is incompatible with layout |
Compared with 1N4744A and BZX84-C16, the HZ16-2J-E delivers superior voltage accuracy and lower noise in a proven through-hole package, making it preferred for metrology-grade analog signal chains where reference stability dominates over power handling or mounting method.

FAQ
What is the exact zener voltage range for HZ16-2J-E?
The HZ16-2J-E has a guaranteed zener voltage range of 15.7 V to 16.5 V when tested at IZ = 0.5 mA and Ta = 25°C, as specified in Table on page 3 of REJ03G0182-0300. This ±0.4 V window reflects tight binning for high-accuracy reference use, distinct from broader-tolerance alternatives like 1N4744A.
Is HZ16-2J-E suitable for surface-mount assembly?
No, the HZ16-2J-E uses a DO-35 axial glass package with 26 mm lead length and is intended for through-hole mounting only. For surface-mount equivalents, consider BZX84-C16 or MMBZ5245B, though neither matches the HZ16-2J-E's low-noise performance or tight VZ tolerance.
What is the maximum reverse leakage current for HZ16-2J-E?
The HZ16-2J-E specifies a maximum reverse leakage current of 1 μA at VR = 2.0 V and Ta = 25°C. This low leakage supports high-impedance reference nodes in op-amp circuits and prevents loading errors in precision voltage divider networks using the HZ16-2J-E.
Does HZ16-2J-E have a documented temperature coefficient?
Yes, the HZ16-2J-E exhibits a zener voltage temperature coefficient of −0.02 %/°C near 16 V, as shown in Figure 2 of REJ03G0182-0300. This value is confirmed for the HZ-L family and applies directly to HZ16-2J-E, enabling accurate drift prediction in temperature-varying environments.
Can HZ16-2J-E replace standard HZ-series diodes in existing designs?
Yes, the HZ16-2J-E is a direct functional upgrade within the same DO-35 package and pinout, offering significantly lower noise (1/3–1/10 of standard HZ series) and tighter VZ tolerance. No PCB changes are required, but designers should verify thermal margin given identical 400 mW Pd rating.
