Product details
Overview
HZS16-2JTA-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized DC power supplies. It delivers a nominal zener voltage of 16.3–17.1 V at 5 mA test current, with dynamic resistance of 12.0 Ω, maximum power dissipation of 400 mW, and junction temperature rating up to 200°C - enabling use in compact industrial power rails and reference circuits.
For engineers reviewing the HZS16-2JTA-E datasheet, HZS16-2JTA-E pinout, HZS16-2JTA-E application, or HZS16-2JTA-E equivalent, key selection criteria include its 16.7 V typical zener voltage, low leakage current (≤1 µA at VR = 12.0 V), tight ±0.4 V tolerance across grade -2, MHD package compatibility with 5 mm-pitch automated insertion, and thermal stability over −55°C to +175°C storage range.
Technical Context
The HZS16-2JTA-E operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse-biased current above its specified zener breakdown threshold. Its planar silicon construction ensures reproducible breakdown characteristics and low noise performance suitable for analog references.
It exhibits a negative zener voltage temperature coefficient of approximately −0.04 %/°C (−4 mV/°C) near 16.7 V, requiring thermal compensation only in high-precision applications. The device is rated for continuous DC operation only - no AC or pulse-rating data is specified.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16.3–17.1 V at IZ = 5 mA - defines regulated output voltage window under standard bias |
| Dynamic Resistance (rd) | 12.0 Ω max at IZ = 5 mA - determines load regulation sensitivity and ripple rejection |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets upper limit for safe continuous DC power handling |
| Reverse Leakage (IR) | ≤1 µA max at VR = 12.0 V - ensures minimal quiescent current in standby or low-current bias networks |
| Junction Temperature (Tj) | 200°C max - supports operation in thermally constrained enclosures or high-ambient industrial environments |
| Storage Temperature | −55°C to +175°C - enables use in wide-range environmental deployments including automotive under-hood proximity |
Pinout & Package
The HZS16-2JTA-E is housed in the MHD package (JEITA code GRZZ0002ZC-A), a miniature axial-lead glass-encapsulated diode format with 2.0 mm body diameter, 26.0 mm lead length, and 5 mm pitch - optimized for high-speed automatic insertion on PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to higher-potential node; reverse-bias terminal where zener breakdown occurs |
| 2 (Non-banded End) | Anode | Connected to lower-potential node (typically circuit ground or return); completes shunt regulation path |
Key Features
| Feature | Design Value |
|---|---|
| Low zener impedance | 12.0 Ω max ensures tight voltage regulation under varying load currents |
| High power density | 400 mW in MHD package enables space-constrained voltage reference design without heatsinking |
| Tight voltage tolerance | Grade -2 designation guarantees 16.3–17.1 V range - ideal for ±2% regulated supply targets |
| Automated assembly compatibility | 5 mm pitch and standardized MHD dimensions support high-throughput SMT-compatible through-hole insertion |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A (ON Semiconductor) | 14 V nominal zener voltage, 1 W power rating, DO-41 package | Higher power but lower voltage; requires PCB layout change due to larger DO-41 footprint | Select when >400 mW surge absorption is needed and 14 V regulation suffices |
| BZX55C16 (Vishay) | 16 V nominal, ±5% tolerance (15.2–16.8 V), 500 mW, DO-35 package | Wider voltage tolerance and higher power, but larger DO-35 body and different lead spacing | Choose for cost-sensitive designs where ±5% regulation tolerance is acceptable and DO-35 insertion is supported |
Compared with 1N4744A and BZX55C16, the HZS16-2JTA-E offers tighter voltage control (±0.4 V vs. ±0.7–0.8 V), smaller MHD footprint for dense layouts, and guaranteed 12.0 Ω dynamic resistance - making it preferable for precision low-power references where board space and regulation accuracy are critical.

FAQ
What is the exact zener voltage range for HZS16-2JTA-E?
The HZS16-2JTA-E has a guaranteed zener voltage range of 16.3 V to 17.1 V when tested at 5 mA DC current, per Renesas datasheet REJ03G0184-0500 Rev.5.00. This corresponds to the "-2" grade designation in the HZS16 family and reflects a ±0.4 V tolerance around the typical 16.7 V value. The HZS16-2JTA-E is not rated for AC or pulsed operation.
Is HZS16-2JTA-E RoHS compliant?
Yes, the HZS16-2JTA-E meets EU RoHS Directive requirements as confirmed by Renesas Electronics' environmental compliance documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits. Full substance declarations are available upon request from Aetrix Electronics.
What is the maximum reverse leakage current for HZS16-2JTA-E?
The maximum reverse leakage current for HZS16-2JTA-E is 1 µA at VR = 12.0 V and Ta = 25°C, as specified in the Electrical Characteristics table on page 4 of the official datasheet. This low leakage supports energy-efficient biasing in battery-powered or always-on reference circuits where standby current must be minimized.
Can HZS16-2JTA-E be used in surface-mount designs?
No - the HZS16-2JTA-E uses the axial-lead MHD package (JEITA GRZZ0002ZC-A) and is intended for through-hole mounting with 5 mm pitch. It is not a surface-mount device. For SMT-compatible alternatives, consider Renesas' HZ3 series in SOD-323 or similar Zener families from other manufacturers with compatible voltage and power ratings.
What is the thermal resistance junction-to-ambient for HZS16-2JTA-E?
The datasheet does not specify junction-to-ambient thermal resistance (RθJA) for the HZS16-2JTA-E. Instead, it provides a derating curve (Fig.3, Page 5) showing power dissipation drops linearly from 400 mW at 25°C ambient to zero at ~150°C. Designers should use this curve - not RθJA - to determine safe operating power at elevated temperatures for the HZS16-2JTA-E.
