Product details
Overview
HZ10BP-JTK-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage reference and stabilization in precision analog circuits, featuring a nominal zener voltage of 10 V (min 9.5 V, max 10.3 V), 400 mW power dissipation, 80 Ω dynamic resistance at 0.5 mA test current, 1 μA maximum reverse leakage at 7.5 V, and DO-35 glass package with orange body and navy-blue cathode band.
For engineers reviewing the HZ10BP-JTK-E datasheet, HZ10BP-JTK-E pinout, HZ10BP-JTK-E application, or HZ10BP-JTK-E equivalent, key selection criteria include zener voltage tolerance (±5% typical), low noise performance (≈1/3–1/10 of standard HZ series), temperature coefficient (−0.04 %/°C at 10 V), junction temperature limit (175°C), and suitability for low-drift reference designs in instrumentation and regulated power supplies.
Technical Context
The HZ10BP-JTK-E operates as a two-terminal voltage reference device using silicon planar Zener breakdown in the 10 V range, where avalanche-dominated conduction yields stable, low-temperature-coefficient regulation. Its design targets low-noise analog systems requiring minimal voltage drift and high impedance stability under varying load and thermal conditions.
It is characterized at DC test conditions (IZ = 0.5 mA), with specified dynamic resistance (rd = 80 Ω) and reverse leakage (IR ≤ 1 μA at VR = 7.5 V), confirming its suitability for high-PSRR, low-current biasing applications such as op-amp reference nodes and sensor excitation circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.5 V min to 10.3 V max at IZ = 0.5 mA - defines stable regulation window for 10 V reference designs |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current (IR) | ≤1 μA at VR = 7.5 V - ensures minimal error current in high-impedance reference paths |
| Junction Temperature (Tj) | 175°C maximum - enables operation in thermally demanding industrial environments |
| Temperature Coefficient (γZ) | −0.04 %/°C at 10 V - quantifies voltage drift per degree Celsius for precision stability budgets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4740A | Zener voltage 10 V ±5%, Pd = 1 W, rd = 17 Ω, DO-41 package, higher power but larger footprint and higher noise | Better suited for higher-current shunt regulation; less optimal for ultra-low-noise analog references | Select when >400 mW dissipation or PCB space allows DO-41; avoid when noise or thermal density is critical |
| BZX55C10 | Zener voltage 10 V ±5%, Pd = 500 mW, rd = 20 Ω, DO-35 package, lower rd but no published noise spec; generic grade | Acceptable for general-purpose regulation; lacks documented low-noise optimization for precision analog use | Choose for cost-sensitive non-critical references; not recommended where HZ-L series noise advantage is required |
Compared with 1N4740A and BZX55C10, the HZ10BP-JTK-E delivers verified low-noise performance and tighter thermal stability in the same DO-35 footprint, making it the preferred choice for instrumentation-grade references where voltage integrity and spectral purity are design-critical.

FAQ
What is the exact zener voltage range for HZ10BP-JTK-E?
The HZ10BP-JTK-E has a guaranteed zener voltage range of 9.5 V minimum to 10.3 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This ±5% tolerance band is confirmed in the Renesas REJ03G0182-0300 datasheet, Page 2, under Electrical Characteristics for the HZ11A1L variant group, which includes HZ10BP-JTK-E as a member of the HZ-L Series 10 V family.
Is HZ10BP-JTK-E suitable for low-noise applications?
Yes, the HZ10BP-JTK-E is explicitly engineered for low-noise operation: Renesas states its noise level is approximately 1/3 to 1/10 that of the standard HZ series. This is achieved through optimized silicon planar Zener structure and process control, making HZ10BP-JTK-E appropriate for precision analog circuits including ADC references and audio preamp biasing.
What package type does HZ10BP-JTK-E use?
HZ10BP-JTK-E uses the DO-35 glass axial package (JEITA code GRZZ0002ZB-A), with orange body color and navy-blue cathode band. Package dimensions are φD = 2.0 mm, E = 4.2 mm, L = 26.0 mm, and typical mass is 0.13 g - fully compliant with SC-40 mechanical standards per Renesas Package Dimensions diagram on Page 5.
What is the maximum power dissipation rating for HZ10BP-JTK-E?
The HZ10BP-JTK-E has a maximum power dissipation (Pd) of 400 mW at ambient temperature Ta = 25°C, as specified in the Absolute Maximum Ratings table (Page 2). Derating is required above 25°C per the "Power Dissipation vs. Ambient Temperature" curve in Figure 3 (Page 4), with zero dissipation at ~150°C.
Does HZ10BP-JTK-E have a specified temperature coefficient?
Yes, the HZ10BP-JTK-E exhibits a zener voltage temperature coefficient (γZ) of −0.04 %/°C at 10 V, as shown in Figure 2 ("Temperature Coefficient vs. Zener Voltage") on Page 4 of the datasheet. This negative coefficient is typical for 10 V Zeners and enables predictable, low-drift behavior across industrial temperature ranges.
