Product details
Overview
HZS10NB3TA-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 9.82–10.30 V at 5 mA test current, with dynamic resistance of 20 Ω, maximum power dissipation of 400 mW, and junction temperature rating up to 200°C. It is used in voltage reference and overvoltage protection circuits for industrial control modules and sensor signal conditioning.
For engineers reviewing the HZS10NB3TA-E datasheet, HZS10NB3TA-E pinout, HZS10NB3TA-E application, or HZS10NB3TA-E equivalent, this page provides verified electrical specifications, package dimensions, thermal derating behavior, zener voltage tolerance grade (B3), and validated alternative parts for supply continuity and design flexibility.
Technical Context
The HZS10NB3TA-E operates as a two-terminal shunt regulator, maintaining stable output voltage across varying load currents by conducting reverse-biased current above its breakdown threshold. Its B3-grade zener voltage tolerance (±2.5% at 10 V) and low dynamic resistance (20 Ω at IZ = 5 mA) support tight regulation in feedback loops and reference buffers.
It features a low leakage current (≤0.2 μA at VR = 7.0 V), high thermal stability (zener voltage temperature coefficient near zero crossing at ~5.6 V, extrapolated to ±0.03%/°C range for 10 V), and is qualified for standard industrial applications per Renesas quality grading - not rated for automotive, medical, or safety-critical use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.82–10.30 V at IZ = 5 mA - defines precise clamping/reference level for 10 V rail stabilization |
| Dynamic Resistance (rd) | 20 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load transients |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - sets maximum continuous DC power handling on standard PCB |
| Reverse Current (IR) | ≤0.2 μA at VR = 7.0 V - guarantees negligible standby leakage in battery-backed or low-IQ systems |
| Junction Temperature (Tj) | 200°C max - enables operation in high-ambient environments such as enclosed industrial enclosures |
| Storage Temperature | –55 to +175°C - supports extended logistics and reflow-compatible assembly processes |

Applications
| Industrial Power Monitor | Embedded Sensor Reference |
|---|---|
|
Use Scenario: Monitoring 12 V DC input rail in PLC I/O modules using resistive divider + ADC. IC Role / Device Role / Timing Role: Zener diode provides stable 10 V reference for ADC full-scale calibration and rail health detection. Use Value: B3-grade tolerance (±2.5%) and 20 Ω rd ensure <±0.5% reference error across temperature and load variations. |
Use Scenario: Biasing analog front-end of temperature/humidity sensor in HVAC controller. IC Role / Device Role / Timing Role: Supplies clean, low-drift 10 V reference to op-amp gain stage and sensor excitation circuit. Use Value: ≤0.2 μA leakage prevents loading of high-Z sensor outputs; 200°C Tj rating supports sealed enclosure operation. |
| Overvoltage Clamp | Linear Regulator Feedback |
|
Use Scenario: Protecting microcontroller GPIO pins from transient surges on 5 V logic lines. IC Role / Device Role / Timing Role: Shunt clamp activated above 10.3 V to divert surge current away from sensitive inputs. Use Value: 400 mW Pd sustains short-duration transients; fast response due to planar silicon construction. |

IC Role / Device Role / Timing Role: Provides accurate 10 V reference to regulator feedback network for stable 15 V output. Use Value: Low rd maintains regulation despite varying feedback current; B3 grade ensures consistent setpoint across batches. |
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 |
|---|---|---|---|
| 1N4740A | Zener voltage 10 V ±5%, rd = 17 Ω, Pd = 1 W, DO-41 package | Higher power rating but looser tolerance; larger footprint and higher thermal mass | Preferred where higher surge energy absorption is required and board space permits DO-41 |
| BZX55-C10 | Zener voltage 10 V ±5%, rd = 20 Ω, Pd = 500 mW, DO-35 package, ±5% grade only | Same package outline but wider voltage tolerance; no B3-equivalent grade available | Suitable for cost-sensitive non-critical references where ±5% tolerance is acceptable |
Compared with HZS10NB3TA-E, the 1N4740A offers higher power handling but sacrifices precision and compactness, while the BZX55-C10 matches the DO-35 form factor but lacks the tighter B3 tolerance needed for mid-accuracy references - making HZS10NB3TA-E optimal for space-constrained industrial designs requiring ±2.5% stability.

FAQ
What is the zener voltage tolerance grade of HZS10NB3TA-E?
The HZS10NB3TA-E carries the B3 grade, specifying a zener voltage range of 9.82–10.30 V at 5 mA test current, corresponding to ±2.5% tolerance around the nominal 10 V rating. This tighter tolerance than B1/B2 grades makes HZS10NB3TA-E suitable for applications demanding improved reference accuracy without resorting to more expensive precision references.
What is the maximum power dissipation of HZS10NB3TA-E at 75°C ambient?
Per Figure 3 in the official Renesas datasheet REJ03G0185-0300 Rev.3.00, the HZS10NB3TA-E's power dissipation derates linearly from 400 mW at 25°C to approximately 280 mW at 75°C ambient when mounted on a standard 100 × 180 × 1.6 mm paper-phenol PCB. This derating must be applied in thermal design to avoid exceeding the 200°C junction limit.
Is HZS10NB3TA-E suitable for automotive applications?
No. HZS10NB3TA-E is classified as a "Standard" quality grade device per Renesas documentation and is explicitly intended for computers, office equipment, industrial robots, and test equipment - not transportation or safety-critical systems. It is not AEC-Q200 qualified, and Renesas prohibits its use in automotive ECUs, ADAS, or any application where failure could endanger human life.
What does the "TA-E" suffix indicate in HZS10NB3TA-E?
The "TA-E" suffix denotes tape-and-reel packaging per JEDEC standard: "TA" indicates 7-inch reel, and "E" specifies embossed carrier tape with 2 mm pitch and 1000 units per reel. This format is optimized for SMT placement equipment and high-volume automated assembly, distinct from bulk or ammo-pack variants.
How does the dynamic resistance of HZS10NB3TA-E affect voltage regulation performance?
The HZS10NB3TA-E's dynamic resistance of 20 Ω (max at 5 mA) directly determines how much its zener voltage shifts under changing load current - for example, a 1 mA change in zener current causes ≤20 mV output variation. This low rd enables stable regulation in feedback networks and reference dividers where load current varies dynamically, improving overall system accuracy.
