Product details
Overview
HZS10NB2TA-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in stabilized power supplies, with a nominal zener voltage of 10.0 V (min 9.82 V, max 10.30 V at IZ = 5 mA), dynamic resistance of 7.0 Ω, and maximum power dissipation of 400 mW. It operates within an ambient temperature range up to +175 °C and features low leakage current (IR ≤ 0.2 μA at VR = 7.0 V), making it suitable for compact, high-reliability DC bias and reference applications.
For engineers reviewing the HZS10NB2TA-E datasheet, HZS10NB2TA-E pinout, HZS10NB2TA-E application, or HZS10NB2TA-E equivalent, this device serves as a stable, low-impedance voltage reference in industrial power management, sensor excitation circuits, and overvoltage protection clamping where tight tolerance and thermal stability are required.
Technical Context
The HZS10NB2TA-E employs a silicon planar junction structure optimized for low zener impedance and minimal temperature drift. Its zener voltage exhibits a positive temperature coefficient near 10 V, resulting in predictable, linear variation across –55 °C to +175 °C operating range.
Designed for through-hole mounting in MHD package (JEITA GRZZ0002ZC-A), it supports high-speed automatic insertion with 5 mm pitch compatibility. The device is rated for junction temperatures up to 200 °C and meets Renesas' Standard quality grade for industrial and office equipment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Zener Voltage (VZ) | 9.82–10.30 V at IZ = 5 mA - defines precise regulation point for feedback loops and reference rails. |
| Dynamic Resistance (rd) | 7.0 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load transients. |
| Reverse Leakage (IR) | ≤ 0.2 μA at VR = 7.0 V - enables low-power standby operation without significant quiescent loss. |
| Power Dissipation (Pd) | 400 mW - supports continuous regulation in compact PCB layouts without forced cooling. |
| Junction Temperature (Tj) | 200 °C max - allows reliable operation in thermally constrained enclosures or high-ambient environments. |

|---|---|
Use Scenario: Providing stable 10 V reference for op-amp-based feedback in 24 V DC-DC converters. IC Role / Device Role / Timing Role: Zener diode acting as shunt voltage reference in error amplifier loop. Use Value: Maintains ±1% output regulation across line/load/temperature due to 7.0 Ω rd and low tempco. |
Use Scenario: Biasing resistive bridge sensors (e.g., strain gauges) requiring precise 10 V excitation. IC Role / Device Role / Timing Role: Fixed-voltage source delivering low-noise, low-drift excitation voltage.

| Overvoltage Clamp Protection | Microcontroller Reset Circuit |
Use Scenario: Clamping transient surges on 12 V supply rail to protect downstream logic ICs. IC Role / Device Role / Timing Role: Shunt protector triggered above 10.3 V to divert excess current. Use Value: Limits peak rail voltage to safe level with 400 mW Pd handling short-duration spikes. |
Use Scenario: Generating clean reset signal for MCU when main supply drops below 9.8 V. IC Role / Device Role / Timing Role: Threshold detector using zener breakdown to trigger reset logic. Use Value: Provides deterministic brown-out detection with B2-grade voltage window (9.82–10.30 V). |
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 = 7 Ω, Pd = 1 W, DO-41 package | Higher power rating but larger footprint; less precise tolerance than HZS10NB2TA-E's B2 grade | Preferred where higher surge energy absorption is needed; not drop-in due to different package and thermal profile. |
| BZX55C10 | Zener voltage 10 V (±5%), rd = 20 Ω, Pd = 500 mW, DO-35 package | Higher dynamic resistance reduces regulation accuracy; smaller glass package limits thermal mass | Acceptable for cost-sensitive, non-critical references; requires layout review due to different lead spacing and thermal decay. |
Compared with 1N4740A and BZX55C10, the HZS10NB2TA-E delivers tighter voltage tolerance (B2 grade), lower dynamic resistance, and optimized thermal performance in the MHD package-making it preferable for space-constrained, high-stability industrial references where precision outweighs raw power handling.

FAQ
What is the zener voltage tolerance for HZS10NB2TA-E?
The HZS10NB2TA-E is specified in B2 grade, with a zener voltage range of 9.82 V to 10.30 V at IZ = 5 mA. This corresponds to approximately ±2.5% tolerance around the nominal 10.0 V rating, verified per Renesas REJ03G0185-0300 Rev.3.00 test conditions. The HZS10NB2TA-E maintains this tolerance across its qualified operating temperature range without derating.
Does HZS10NB2TA-E support automatic insertion in manufacturing?
Yes, the HZS10NB2TA-E uses the MHD package (JEITA GRZZ0002ZC-A) with standardized 5 mm lead pitch and axial orientation, explicitly designed for high-speed automatic insertion equipment. Its mechanical dimensions-including 2.0 mm body diameter and 26.0 mm length-are optimized for pick-and-place and wave solder compatibility, as confirmed in the Renesas package drawing.
What is the maximum reverse leakage current for HZS10NB2TA-E?
The HZS10NB2TA-E has a maximum reverse leakage current (IR) of 0.2 μA at VR = 7.0 V, measured at Ta = 25 °C. This low leakage supports ultra-low-power applications such as battery-backed sensor nodes and standby-mode voltage monitoring circuits where quiescent current must remain below 1 μA.
Can HZS10NB2TA-E be used in automotive under-hood applications?
No-HZS10NB2TA-E is rated for Renesas' Standard quality grade, intended for computers, office equipment, and industrial robots-not transportation equipment. While its junction temperature rating reaches 200 °C, it lacks AEC-Q200 qualification or automotive-specific reliability testing. For under-hood use, Renesas' "High Quality" grade devices (e.g., specific HZS variants with automotive qualification) must be selected instead of HZS10NB2TA-E.
How does the dynamic resistance of HZS10NB2TA-E affect regulation accuracy?
The HZS10NB2TA-E has a maximum dynamic resistance (rd) of 7.0 Ω at IZ = 5 mA, meaning a 1 mA change in zener current causes ≤7 mV output shift. This low rd directly improves load regulation and ripple rejection in feedback networks-critical for maintaining ±0.5% output stability in switching power supplies where the HZS10NB2TA-E serves as reference.
