Product details
Overview
HZS16-3TD-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies, with a nominal zener voltage of 16.3–17.1 V at 5 mA test current, 400 mW power dissipation, and dynamic resistance of 45 Ω - used in voltage reference and overvoltage protection circuits for industrial control modules.
For engineers reviewing the HZS16-3TD-E datasheet, HZS16-3TD-E pinout, HZS16-3TD-E application, or HZS16-3TD-E equivalent, this device serves as a discrete voltage clamp with tight tolerance (±0.4 V), low leakage (<1 µA at 13 V), and high thermal stability (−55 to +175 °C storage range) in compact MHD package for space-constrained PCB designs.
Technical Context
The HZS16-3TD-E operates as a two-terminal voltage reference using silicon planar junction technology, optimized for DC stabilization with specified test conditions of IZ = 5 mA and Ta = 25 °C. Its zener voltage exhibits a positive temperature coefficient near 16 V, enabling predictable drift behavior in ambient-temperature-varying environments.
It features low dynamic impedance (45 Ω), ensuring minimal output voltage variation under load transients, and is rated for junction temperatures up to 200 °C - supporting reliable operation in thermally demanding embedded power rails and sensor interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16.3–17.1 V at IZ = 5 mA - defines stable clamping threshold for 15–18 V supply rails |
| Power Dissipation (Pd) | 400 mW - supports continuous regulation without heatsinking in low-current bias networks |
| Dynamic Resistance (rd) | 45 Ω - limits output voltage shift to ≤225 mV per 5 mA load change |
| Reverse Leakage Current (IR) | <1 µA at VR = 13 V - ensures negligible quiescent current in standby-mode references |
| Junction Temperature (Tj) | 200 °C maximum - enables use in high-ambient industrial enclosures without derating |
| Storage Temperature | −55 to +175 °C - compatible with reflow soldering and extended environmental qualification |
Pinout & Package
Package: MHD (JEITA code GRZZ0002ZC-A), molded plastic with axial leads, 2.0 mm diameter, 26 mm body length, 5 mm lead pitch - optimized for high-speed automatic insertion and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener voltage reference terminal | Connected to regulated node; polarity-sensitive - reverse-biased during normal operation |
| 2 (Anode) | Reference ground return | Provides current path to circuit common; must be tied to lowest potential point in clamp network |
Key Features
| Feature | Design Value |
|---|---|
| Low zener impedance | 45 Ω ensures <±25 mV regulation error across ±2 mA load variation |
| Wide zener voltage range coverage | Part of HZS Series spanning 1.6–38 V - allows single-source selection for multi-rail systems |
| High reliability construction | Silicon planar junction with glass passivation - achieves <100 ppm/1000h failure rate under rated stress |
| Automated assembly compatibility | 5 mm pitch and standardized MHD outline support pick-and-place and inline insertion |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A (ON Semiconductor) | Zener voltage 14 V ±5%, Pd = 1 W, rd = 23 Ω - higher power but lower voltage grade | Used where higher surge energy absorption is required, not for tight 16.5 V regulation | Select only if system requires ≥1 W clamping and can tolerate 14 V threshold |
| BZX84-C16 (Diodes Inc.) | SOT-23 package, VZ = 16 V ±5%, Pd = 350 mW, rd = 40 Ω - surface-mount, lower power rating | Fits dense PCB layouts but lacks axial-leaded mechanical robustness for high-vibration environments | Prefer for space-constrained consumer electronics; avoid in industrial vibration-prone mounts |
Compared with 1N4744A and BZX84-C16, the HZS16-3TD-E delivers tighter voltage tolerance (±0.4 V vs. ±5%), axial-leaded mechanical stability, and exact 16.3–17.1 V range matching legacy Renesas-based designs - making it optimal for replacement in existing industrial power supply revisions.
