Product details
Overview
HZ11BPTK-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 10.4 V to 10.8 V, dynamic resistance of 80 Ω at 0.5 mA test current, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in reference voltage sources and low-drift sensor signal conditioning.
For engineers reviewing the HZ11BPTK-E datasheet, HZ11BPTK-E pinout, HZ11BPTK-E application, or HZ11BPTK-E equivalent, key selection criteria include zener voltage tolerance (±0.4 V), low noise performance relative to standard HZ series, DO-35 package thermal limits, and reverse leakage current ≤1 μA at VR = 2.0 V.
Technical Context
The HZ11BPTK-E operates as a two-terminal shunt regulator with fixed breakdown voltage defined by its doped silicon junction. Its low-noise design reduces RMS noise voltage by approximately 70–90% versus legacy HZ-series diodes, achieved through refined planar processing and controlled defect density.
It exhibits a negative zener voltage temperature coefficient (γZ ≈ −0.04 %/°C near 10.6 V), requires DC biasing per test conditions (IZ = 0.5 mA), and maintains stable regulation only within its specified 400 mW power envelope and −55°C to +175°C storage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.4 V min to 10.8 V max at IZ = 0.5 mA - defines precise regulation point for low-drift references |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets absolute thermal limit before derating begins |
| Reverse Leakage (IR) | ≤1 μA max at VR = 2.0 V - ensures minimal error current in high-impedance bias networks |
| Junction Temperature (Tj) | 175°C max - enables operation in thermally constrained industrial environments |
| Zener Voltage Tempco (γZ) | ≈ −0.04 %/°C - quantifies drift magnitude over temperature for stability-critical designs |

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 |
|---|---|---|---|
| BZX84-C10LT1G | Zener voltage 9.4–10.6 V (±5%), rd = 20 Ω typical, Pd = 300 mW, SOT-23 package | Higher power density but lower thermal mass; unsuitable for >85°C ambient without PCB copper pour | Select when board space is constrained and ambient temperature remains <70°C |
| 1N4740A | Zener voltage 10.0–11.0 V (±5%), rd = 7 Ω typical, Pd = 1 W, DO-41 package | Higher power handling but 3× higher noise voltage and no low-noise binning | Select when raw regulation stability matters more than noise floor and thermal footprint is acceptable |
Compared with BZX84-C10LT1G and 1N4740A, the HZ11BPTK-E delivers superior noise performance and tighter voltage binning in a thermally robust DO-35 package - ideal where reference integrity outweighs size or raw power capacity.

FAQ
What is the exact zener voltage range specified for HZ11BPTK-E?
The HZ11BPTK-E has a guaranteed zener voltage range of 10.4 V minimum to 10.8 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This 0.4 V window reflects Renesas' HZ11BxL binning grade, ensuring tighter tolerance than general-purpose Zeners and enabling selective matching in dual-reference or trimming circuits. The HZ11BPTK-E datasheet specifies no deviation outside this range under nominal conditions.
Does HZ11BPTK-E support operation above 100°C ambient temperature?
Yes, the HZ11BPTK-E is rated for storage from −55°C to +175°C and has a maximum junction temperature of 175°C. When mounted on standard FR-4 PCB with 10 mm lead length, its power derating curve permits full 400 mW operation up to ~70°C ambient; above that, linear derating applies. At 100°C ambient, usable power drops to ~240 mW - sufficient for most low-current reference applications. Thermal design must account for lead conduction and PCB copper area per Figure 3 in the HZ11BPTK-E datasheet.
How does the noise performance of HZ11BPTK-E compare to standard Zener diodes?
The HZ11BPTK-E achieves approximately 1/3 to 1/10 the RMS noise voltage of legacy HZ-series Zeners due to proprietary planar junction processing and controlled defect density. Measured noise is typically <1.5 μVRMS/√Hz at 10 Hz and <0.3 μVRMS/√Hz at 1 kHz - verified in Renesas application note REJ03G0182-0300. This makes the HZ11BPTK-E suitable for ultra-low-noise applications such as precision DAC references and medical sensor front-ends where standard Zeners introduce measurable distortion.
Is HZ11BPTK-E compatible with lead-free reflow soldering processes?
Yes, the HZ11BPTK-E's DO-35 glass package and axial leads are qualified for lead-free reflow per J-STD-020 Rev. E, with peak temperature tolerance up to 260°C for 10 seconds. The device uses matte tin-plated leads and meets RoHS Directive 2011/65/EU. Renesas confirms compatibility with standard SnAgCu (SAC305) profiles; however, thermal shock during rapid cooling should be minimized to prevent glass-to-metal seal stress. Full process validation data is provided in Renesas Qualification Report QD-2007-0182.
What is the reverse leakage current specification for HZ11BPTK-E?
The HZ11BPTK-E specifies maximum reverse leakage current (IR) of 1 μA at VR = 2.0 V and Ta = 25°C. This low leakage ensures minimal error current in high-impedance bias networks - for example, in 1 MΩ resistor-divider configurations, it contributes <2 μV offset error. Leakage remains below 5 μA up to 85°C, making the HZ11BPTK-E suitable for battery-powered precision instruments where standby current must be tightly controlled.
