Product details
Overview
HZS3.6NB1TA-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies. It delivers a nominal zener voltage of 3.62 V to 3.83 V at 5 mA test current, with dynamic resistance of 10 Ω max, reverse leakage ≤1.0 μA at 1.0 V, and 400 mW power dissipation in an MHD package.
For engineers reviewing the HZS3.6NB1TA-E datasheet, HZS3.6NB1TA-E pinout, HZS3.6NB1TA-E application, or HZS3.6NB1TA-E equivalent, this device serves as a compact, high-stability reference element in analog sensing circuits, voltage clamping networks, and biasing stages where tight tolerance (±5.6% zener voltage spread) and low temperature coefficient are critical.
Technical Context
The HZS3.6NB1TA-E operates as a two-terminal shunt regulator, maintaining stable output voltage across varying load currents by conducting excess current to ground when input exceeds its breakdown threshold. Its planar construction ensures consistent junction characteristics and low noise performance.
Designed for operation at 5 mA nominal zener current, it exhibits a zener voltage temperature coefficient near zero (≈0 mV/°C) within the 3.6 V range, minimizing drift over ambient temperature changes from –55°C to +175°C storage and up to +200°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.62 V to 3.83 V at IZ = 5 mA - defines precise clamping/reference level for feedback loops or voltage references |
| Dynamic Resistance (rd) | ≤10 Ω at IZ = 5 mA - ensures minimal output voltage variation under changing load conditions |
| Reverse Leakage Current (IR) | ≤1.0 μA at VR = 1.0 V - guarantees low standby power loss in battery-sensitive applications |
| Power Dissipation (Pd) | 400 mW - supports continuous regulation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | +200°C maximum - enables reliable operation in high-temperature industrial environments |
| Package | MHD (JEITA GRZZ0002ZC-A) - surface-mount compatible, 5 mm pitch for high-speed automated insertion |
Pinout & Package
MHD package: axial-leaded, cylindrical glass body, cathode band marked, dimensions L = 26.0 mm (max), φD = 2.0 mm (nom), mass ≈ 0.084 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener terminal accepting regulated input | Connected to higher-potential node; conducts when forward-biased or during transient overvoltage |
| 2 (Anode) | Reference/ground return path | Typically tied to system ground or common reference; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low zener impedance | 10 Ω max ensures stable regulation under dynamic load transients |
| Wide operating temperature range | –55°C to +175°C storage and +200°C junction rating suit harsh industrial deployments |
| Tight zener voltage tolerance | B1 grade (±5.6%) enables predictable circuit behavior without post-production trimming |
| Low leakage current | ≤1.0 μA at 1.0 V reduces quiescent power draw in always-on monitoring systems |

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 |
|---|---|---|---|
| 1N4728A (ON Semiconductor) | Zener voltage 3.3 V ±5%, Pd = 1 W, DO-41 package, rd = 10 Ω | Higher power rating but larger footprint; less suitable for space-constrained SMT designs | Choose when higher surge energy handling is required and board area permits axial leaded DO-41 |
| BZX55-C3V6 (Vishay) | Zener voltage 3.6 V ±5%, Pd = 500 mW, DO-35 package, rd = 90 Ω | Higher dynamic resistance degrades regulation accuracy under fast load steps | Acceptable for basic voltage referencing where ±2% output stability suffices and cost is primary constraint |
Compared with 1N4728A and BZX55-C3V6, the HZS3.6NB1TA-E offers tighter voltage tolerance within a compact MHD package optimized for automated assembly, lower leakage, and superior thermal robustness-making it preferred for precision industrial and automotive subsystems requiring long-term stability.

FAQ
What is the exact zener voltage range specified for HZS3.6NB1TA-E?
The HZS3.6NB1TA-E has a guaranteed zener voltage range of 3.62 V to 3.83 V when tested at IZ = 5 mA and Ta = 25°C. This B1-grade tolerance (±5.6%) is confirmed in the Renesas REJ03G0185-0300 datasheet, page 2, and applies specifically to the HZS3.6NB1TA-E variant-not the broader HZS3.6N series.
Does HZS3.6NB1TA-E support surface-mount assembly?
No-HZS3.6NB1TA-E uses the MHD package, which is an axial-leaded glass-body configuration designed for through-hole mounting and high-speed automatic insertion at 5 mm pitch. It is not a surface-mount device; Renesas does not list an SMD variant for this specific part number in the HZS-N Series documentation.
What is the maximum junction temperature rating for HZS3.6NB1TA-E?
The HZS3.6NB1TA-E has a maximum junction temperature (Tj) rating of +200°C, as specified in the Absolute Maximum Ratings table on page 2 of the Renesas REJ03G0185-0300 datasheet. This enables operation in high-ambient environments such as motor control enclosures or under-hood automotive modules.
How does the dynamic resistance of HZS3.6NB1TA-E affect regulation performance?
The HZS3.6NB1TA-E specifies dynamic resistance (rd) ≤10 Ω at IZ = 5 mA. This low value means the output voltage varies by no more than 50 mV for a 5 mA load step-critical for maintaining ADC reference stability or protecting sensitive logic inputs from ripple-induced errors in the HZS3.6NB1TA-E's target applications.
Is HZS3.6NB1TA-E compliant with RoHS and halogen-free requirements?
Yes-Renesas confirms environmental compliance for the HZS-N Series in accordance with EU RoHS Directive (2011/65/EU) and halogen-free standards. The REJ03G0185-0300 datasheet states compliance on page 6, and Renesas product change notices confirm material content conformity for HZS3.6NB1TA-E under standard manufacturing lots.
