Product details
Overview
HZS16-3LTD-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 16.3–17.1 V, 400 mW power dissipation, and dynamic resistance of 14.0 Ω at 0.5 mA test current - deployed in stabilized power supplies, sensor signal conditioning, and industrial instrumentation.
For engineers reviewing the HZS16-3LTD-E datasheet, HZS16-3LTD-E pinout, HZS16-3LTD-E application, or HZS16-3LTD-E equivalent, key selection criteria include zener voltage tolerance (±0.4 V), low noise performance (1/3–1/10 that of HZ series), temperature coefficient behavior near zero crossing (~0 mV/°C at ~16 V), and MHD package compatibility with 5 mm-pitch high-speed automatic insertion.
Technical Context
This device operates as a two-terminal voltage reference using silicon planar junction technology, with zener breakdown mechanism dominant in its 16.3–17.1 V range. Its low dynamic impedance (14.0 Ω) and tight voltage tolerance support stable regulation under varying load currents up to 0.5 mA.
Designed for low-noise applications, the HZS16-3LTD-E achieves reduced diode noise through optimized doping and junction geometry - verified by comparative measurement against legacy HZ-series parts. It exhibits a near-zero zener voltage temperature coefficient (γZ ≈ 0 mV/°C) within its specified operating range, minimizing drift in precision references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16.3 V min to 17.1 V max at IZ = 0.5 mA - defines stable reference point for feedback loops in linear regulators or ADC references. |
| Dynamic Resistance (rd) | 14.0 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under small-signal load transients. |
| Power Dissipation (Pd) | 400 mW maximum at Ta = 25°C - sets thermal design limit for PCB trace width and copper area in surface-mount layouts. |
| Reverse Leakage Current (IR) | 1 μA max at VR = 12.0 V - guarantees negligible error current in high-impedance bias networks. |
| Junction Temperature (Tj) | 200°C maximum - enables operation in industrial environments with elevated ambient temperatures when properly heatsinked. |
| Zener Voltage Temp. Coeff. (γZ) | ≈0 mV/°C near 16.5 V - minimizes thermal drift in unbuffered reference designs without external compensation. |
Pinout & Package
Package: MHD (JEITA code GRZZ0002ZC-A), molded plastic with axial leads, 2.0 mm diameter body, 26.0 mm lead length, 5 mm pitch - compatible with automated insertion equipment and standard PCB footprints for through-hole Zener diodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated positive rail; reverse-biased during normal operation to maintain fixed voltage drop. |
| 2 (Anode) | Reference ground node | Tied to circuit common; establishes return path for zener current and defines reference potential. |
Key Features
| Feature | Design Value |
|---|---|
| Noise performance | Approximately 1/3–1/10 lower than HZ-series Zeners - directly improves SNR in precision op-amp biasing and low-level sensor front-ends. |
| Zener voltage range | 16.3–17.1 V with ±0.4 V tolerance - supports accurate 16.5 V system references without trimming resistors. |
| Low leakage current | ≤1 μA at 12 V reverse bias - prevents loading errors in high-impedance voltage divider networks. |
| Thermal stability | Near-zero temperature coefficient at nominal VZ - eliminates need for external temp-compensation in many industrial reference designs. |
Applications
| Industrial Power Supply Reference | High-Precision Sensor Signal Conditioning |

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 |
|---|---|---|---|
| 1N4744A | Zener voltage 14 V (±5%), rd = 23 Ω, Pd = 1 W, DO-41 package | Higher power but wider VZ tolerance and higher noise - suitable for non-critical supply rails only | Select when higher power handling is required and ±5% VZ tolerance is acceptable. |
| BZX85C16 | Zener voltage 16 V (±5%), rd = 40 Ω, Pd = 1.3 W, DO-41 package | Higher dynamic impedance and no low-noise optimization - less suitable for precision analog front-ends | Choose for cost-sensitive general-purpose regulation where noise and tempco are secondary. |
Compared with 1N4744A and BZX85C16, the HZS16-3LTD-E delivers tighter voltage tolerance (±0.4 V vs. ±5%), lower dynamic resistance (14.0 Ω vs. ≥23 Ω), and quantifiably lower noise - making it uniquely suited for metrology-grade references where long-term stability and signal integrity are critical.

FAQ
What is the exact zener voltage range for HZS16-3LTD-E?
The HZS16-3LTD-E has a guaranteed zener voltage range of 16.3 V minimum to 17.1 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This 0.8 V span reflects tight process control for precision reference use, and the typical value falls near 16.7 V. The HZS16-3LTD-E datasheet specifies no derating for temperature or current beyond the stated test condition.
Does HZS16-3LTD-E have a documented temperature coefficient?
Yes - the HZS16-3LTD-E exhibits a zener voltage temperature coefficient (γZ) near zero mV/°C at its nominal operating point (~16.5 V), as confirmed by Figure 2 in the official Renesas datasheet REJ03G0166-0300. This behavior minimizes thermal drift in unbuffered reference designs and is intrinsic to the silicon planar junction structure used in the HZS-L Series.
Is HZS16-3LTD-E RoHS compliant and lead-free?
Yes - the HZS16-3LTD-E conforms to EU RoHS Directive requirements, as confirmed by Renesas' environmental compliance documentation. The MHD package uses lead-free terminations and halogen-free molding compound, and full material declarations are available upon request from Aetrix Electronics for qualifying customers.
What is the maximum reverse leakage current for HZS16-3LTD-E?
The HZS16-3LTD-E has a maximum reverse leakage current (IR) of 1 μA when measured at VR = 12.0 V and Ta = 25°C. This low leakage ensures minimal error contribution in high-impedance bias networks and makes the HZS16-3LTD-E suitable for battery-powered precision instruments where quiescent current matters.
Can HZS16-3LTD-E be used in surface-mount designs?
No - the HZS16-3LTD-E uses the axial-lead MHD package (JEITA code GRZZ0002ZC-A) designed for through-hole mounting and 5 mm-pitch automatic insertion. It is not a surface-mount device. For SMD alternatives, engineers should consider Renesas' HZS-L Series variants in MHDV or consult Aetrix for qualified SMT-compatible Zener replacements with matching electrical specs.
