Product details
Overview
HZS5.6NB1TA-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 5.6 V (min 5.29 V, max 5.52 V), dynamic resistance of 2.5 Ω at 5 mA test current, and maximum power dissipation of 400 mW in the MHD package. Its low leakage and tight voltage tolerance support reliable reference and clamp functions in consumer and industrial power rails.
For engineers reviewing the HZS5.6NB1TA-E datasheet, HZS5.6NB1TA-E pinout, HZS5.6NB1TA-E application, or HZS5.6NB1TA-E equivalent, key selection criteria include zener voltage accuracy (B1 grade ±4.5%), thermal coefficient behavior near 5.6 V, junction temperature limit of 200°C, and compatibility with 5 mm-pitch automated insertion processes.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction. Its B1-grade specification ensures tighter zener voltage tolerance than B2/B3 variants, with reverse current limited to ≤5 μA at VR = 1.0 V and dynamic impedance measured at 5 mA DC test current.
The HZS5.6NB1TA-E exhibits a positive temperature coefficient near 5.6 V (≈+2 mV/°C per Fig.2), enabling stable regulation across –55°C to +175°C storage range. It is rated for continuous operation up to 200°C junction temperature and requires no external biasing - functioning solely as a passive shunt regulator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.29 V to 5.52 V at IZ = 5 mA - defines regulated output voltage window under nominal bias |
| Dynamic Resistance (rd) | 2.5 Ω max at IZ = 5 mA - determines load regulation sensitivity and ripple rejection capability |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets absolute thermal limit before derating per Fig.3 |
| Reverse Current (IR) | ≤5 μA at VR = 1.0 V - ensures minimal quiescent current in standby/clamp modes |
| Junction Temperature (Tj) | 200°C max - enables operation in high-ambient industrial environments with appropriate PCB copper area |
| Package | MHD (JEITA GRZZ0002ZC-A) - 2-pin axial leaded package optimized for 5 mm-pitch auto-insertion |
Pinout & Package
The HZS5.6NB1TA-E uses the MHD axial-leaded package (JEITA code GRZZ0002ZC-A), with cathode identified by a black band. Total mass is 0.084 g; lead spacing is 5 mm nominal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Banded End) | Cathode | Connected to regulated voltage node; carries reverse-biased current during regulation |
| 2 (Non-banded End) | Anode | Connected to ground or lower-potential rail; completes shunt path for excess current |
Key Features
| Feature | Design Value |
|---|---|
| Low zener impedance | 2.5 Ω max ensures <10 mV output shift per 25 mA load change at 5 mA bias |
| B1-grade voltage tolerance | ±4.5% zener voltage spread enables tighter system-level reference accuracy vs. B2/B3 grades |
| 400 mW power rating | Supports ≥100 mA short-circuit clamping current at 5.6 V without thermal runaway |

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 |
|---|---|---|---|
| 1N4734A (ON Semiconductor) | Zener voltage 5.6 V ±5%, Pd = 1 W, DO-41 package, rd = 5 Ω | Higher power rating but larger footprint and looser voltage tolerance | Select when >400 mW dissipation or through-hole hand-soldering is required |
| BZX55-C5V6 (Vishay) | Zener voltage 5.6 V ±5%, Pd = 500 mW, DO-35 package, rd = 10 Ω | Higher power and standard DO-35 form factor, but higher impedance and wider tolerance | Select when legacy DO-35 board compatibility or marginally higher power is needed |
Compared with 1N4734A and BZX55-C5V6, the HZS5.6NB1TA-E offers tighter B1-grade voltage control and lower dynamic impedance in a compact MHD package optimized for automated assembly - making it preferable for space-constrained, high-accuracy, high-volume production where 400 mW suffices.

FAQ
What is the zener voltage tolerance for HZS5.6NB1TA-E?
The HZS5.6NB1TA-E has a B1-grade zener voltage specification of 5.29 V minimum to 5.52 V maximum at 5 mA test current, corresponding to ±4.5% tolerance around the nominal 5.6 V rating. This tighter tolerance than B2/B3 grades supports higher-accuracy voltage references in regulated power supplies and sensing circuits where HZS5.6NB1TA-E is deployed.
Does HZS5.6NB1TA-E require a series current-limiting resistor in operation?
Yes, HZS5.6NB1TA-E must be used with an external series current-limiting resistor to ensure its operating current remains within safe bounds - typically between 1 mA and 50 mA depending on power dissipation and thermal design. The resistor value is calculated based on input voltage, desired zener current, and the 5.6 V regulation point; exceeding 400 mW dissipation risks thermal failure of the HZS5.6NB1TA-E.
What is the thermal resistance characteristic of HZS5.6NB1TA-E?
The HZS5.6NB1TA-E does not specify junction-to-ambient thermal resistance (RθJA) directly, but its power derating curve (Fig.3) shows linear reduction from 400 mW at 25°C ambient to zero at ~150°C on a standard 100 × 180 × 1.6 mm paper-phenol PCB. Effective thermal management requires adequate copper pour on both anode and cathode pads to sustain continuous operation - critical for reliability when HZS5.6NB1TA-E regulates in high-temperature industrial environments.
Is HZS5.6NB1TA-E suitable for automotive applications?
HZS5.6NB1TA-E is classified as a "Standard" quality grade device per Renesas documentation, intended for computers, office equipment, communications gear, and industrial robots - not for automotive safety-critical systems. It lacks AEC-Q200 qualification and is not recommended for under-hood or ADAS applications; for such use cases, Renesas offers qualified alternatives like the RZ series, not the HZS-N family including HZS5.6NB1TA-E.
How does the temperature coefficient of HZS5.6NB1TA-E affect regulation stability?
HZS5.6NB1TA-E exhibits a positive temperature coefficient of approximately +2 mV/°C near 5.6 V (per Fig.2), meaning its zener voltage increases linearly with junction temperature. This behavior improves stability when compensating for components with negative tempcos (e.g., LEDs or bipolar transistors), but requires thermal-aware layout to minimize self-heating effects - especially important in sealed enclosures where HZS5.6NB1TA-E may operate above 85°C ambient.
