Product details
Overview
HZS22-1TD-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 22.3–23.3 V at 2 mA test current, 65 Ω dynamic resistance, and 400 mW maximum power dissipation in an MHD package. It serves as a shunt reference in feedback loops of DC-DC converters and linear regulators for industrial instrumentation.
For engineers reviewing the HZS22-1TD-E datasheet, HZS22-1TD-E pinout, HZS22-1TD-E application, or HZS22-1TD-E equivalent, key selection criteria include zener voltage tolerance (±0.5 V), temperature coefficient (−0.04 %/°C), low leakage (<1 µA at 17.6 V), junction temperature rating (200°C), and compatibility with 5 mm-pitch automated insertion equipment.
Technical Context
The HZS22-1TD-E operates as a two-terminal shunt voltage regulator, maintaining stable output voltage by conducting reverse current when input exceeds its zener breakdown threshold. Its silicon planar construction ensures consistent breakdown characteristics and low noise performance across temperature.
It exhibits a negative temperature coefficient of −0.04 %/°C (≈ −8.8 mV/°C) near 22 V, enabling predictable drift compensation in reference circuits. The device is rated for continuous operation up to 200°C junction temperature and supports storage from −55°C to +175°C.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 22.3–23.3 V at IZ = 2 mA - defines precise regulation point for feedback networks |
| Dynamic Resistance (rd) | 65 Ω max at IZ = 2 mA - determines load regulation sensitivity and ripple rejection |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets thermal derating limit for PCB layout and heatsinking |
| Reverse Leakage (IR) | <1 µA at VR = 17.6 V - ensures minimal quiescent current in standby mode |
| Junction Temperature (Tj) | 200°C max - enables reliable operation in high-ambient industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4747A | Zener voltage 20 V ±5%, rd = 25 Ω, Pd = 1 W, DO-41 package | Higher power but looser tolerance; requires larger PCB footprint | Preferred where higher surge energy handling is needed and 20 V regulation suffices |
| BZX84-C22 | Zener voltage 22 V ±5%, rd = 50 Ω, Pd = 300 mW, SOT-23 package | Surface-mount only; lower power rating limits continuous regulation duty | Selected for space-constrained PCBs where 22 V ±5% tolerance is acceptable |
Compared with 1N4747A and BZX84-C22, the HZS22-1TD-E offers tighter voltage tolerance (±0.5 V vs. ±5%), higher temperature capability (200°C vs. 150–175°C), and axial-leaded MHD packaging optimized for automated through-hole assembly-making it optimal for industrial-grade power monitoring and PLC modules requiring long-term stability.

FAQ
What is the exact zener voltage range specified for HZS22-1TD-E?
The HZS22-1TD-E has a guaranteed zener voltage range of 22.3 V to 23.3 V when tested at IZ = 2 mA and Ta = 25°C. This ±0.5 V tolerance reflects the "-2" grade within the HZS22 series, confirmed in the Electrical Characteristics table on page 4 of REJ03G0184-0500 Rev.5.00. The HZS22-1TD-E is not rated for 22.0 V or 24.0 V endpoints.
Does HZS22-1TD-E support surface-mount assembly?
No, the HZS22-1TD-E uses the MHD axial-leaded package (JEITA code GRZZ0002ZC-A) with 26 mm body length and 5 mm lead pitch, designed exclusively for through-hole mounting and high-speed automatic insertion. It is not compatible with reflow or wave soldering processes intended for SMT packages like SOD-123 or SOT-23. Surface-mount alternatives require different part numbers such as BZX84-C22.
What is the maximum reverse leakage current for HZS22-1TD-E at 17.6 V?
The maximum reverse leakage current for HZS22-1TD-E is 1 µA when measured at VR = 17.6 V (80% of nominal VZ) and Ta = 25°C, as specified in the Electrical Characteristics table on page 4. This low leakage ensures minimal parasitic loading in high-impedance reference circuits and contributes to stable operation in battery-backed systems.
Is HZS22-1TD-E qualified for automotive applications?
No, the HZS22-1TD-E is classified as a "Standard" quality grade device per Renesas' quality grading system (page 1 of REJ03G0184-0500), intended for industrial, office, and consumer equipment-not transportation or safety-critical systems. It lacks AEC-Q101 qualification and is not recommended for under-hood automotive use without additional validation and written consent from Renesas Electronics.
How does the temperature coefficient of HZS22-1TD-E affect circuit design?
The HZS22-1TD-E has a temperature coefficient of −0.04 %/°C (≈ −8.8 mV/°C), meaning its zener voltage decreases predictably with rising temperature. Designers can compensate for this drift using resistor networks or complementary components in precision references. This coefficient is verified in Figure 2 of the datasheet and applies across the full operating temperature range, supporting stable performance in unregulated ambient environments.
