Product details
Overview
HZ30BPTN-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 30.2 V to 31.6 V at 0.5 mA test current, dynamic resistance of 27.0 Ω max, 400 mW power dissipation, and DO-35 glass package with orange body and navy blue cathode band. It serves in stabilized reference supplies for instrumentation amplifiers and sensor signal conditioning.
For engineers reviewing the HZ30BPTN-E datasheet, HZ30BPTN-E pinout, HZ30BPTN-E application, or HZ30BPTN-E equivalent, key selection criteria include zener voltage tolerance (±2.3% at 30.9 V nominal), low noise performance (1/3–1/10 that of standard HZ series), temperature coefficient (−0.04 %/°C typical), and thermal derating above 25°C ambient.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a silicon planar junction, with low leakage current (<1 μA at VR = 27.0 V) and tightly controlled zener impedance to minimize output ripple in low-current bias networks. Its DO-35 package enables through-hole mounting in space-constrained analog PCBs requiring stable DC references.
The HZ30BPTN-E belongs to the HZ-L Series, which employs process enhancements to reduce flicker and thermal noise versus legacy HZ parts-critical for high-resolution ADC references and low-drift op-amp biasing where voltage stability over time and temperature is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30.2 V min to 31.6 V max at IZ = 0.5 mA - defines precise DC reference level for calibration-critical circuits |
| Dynamic Resistance (rd) | 27.0 Ω max at IZ = 0.5 mA - ensures minimal output voltage shift under load variation |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports continuous operation in compact linear regulator stages |
| Reverse Leakage (IR) | 1 μA max at VR = 27.0 V - prevents parasitic current paths in high-impedance reference nodes |
| Junction Temperature (Tj) | 175°C max - enables reliable operation in industrial environments with elevated ambient temperatures |
| Noise Reduction | ≈1/3–1/10 vs. HZ series - directly improves SNR in audio preamps and precision measurement front-ends |
Pinout & Package
Package: DO-35 glass axial lead package (JEITA code GRZZ0002ZB-A, Renesas code SC-40), orange body with navy blue cathode band, mass 0.13 g, dimensions φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-impedance reference node | Connected to regulated output; polarity must be observed to avoid reverse conduction in bias networks |
| 2 (Anode) | Ground or current sink terminal | Biased via series resistor to establish IZ; forms low-noise reference path when decoupled |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener structure | Reduces broadband voltage noise by factor of 3–10 vs. standard HZ diodes-critical for sub-16-bit ADC references |
| Tight zener voltage tolerance | ±2.3% (30.2–31.6 V range) enables single-part replacement without trimming in production calibration |
| Negligible temperature drift | −0.04 %/°C typical coefficient minimizes reference error across −40°C to +125°C operating range |
| Stable low-current operation | Specified at IZ = 0.5 mA-supports ultra-low-power biasing in battery-operated sensor nodes |
| Robust thermal rating | 175°C max junction temperature allows use in sealed enclosures with limited airflow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5262BLT1G | Zener voltage 30 V ±5%, rd = 45 Ω max, SOT-23 package, 350 mW Pd | SMT-compatible but higher impedance and wider tolerance; less suitable for <16-bit precision systems | Select when board space is constrained and ±5% voltage accuracy is acceptable |
| Vishay BZX84-C30 | Zener voltage 30 V ±5%, rd = 50 Ω max, SOT-23, 350 mW Pd, no low-noise optimization | Lacks documented noise reduction; not validated for high-SNR analog signal chains | Use only in non-critical power rail clamping or coarse voltage limiting |
Compared with HZ30BPTN-E, the MMBZ5262BLT1G offers surface-mount convenience but sacrifices 67% higher dynamic resistance and looser voltage tolerance-reducing reference stability in precision analog designs-while the BZX84-C30 lacks low-noise specification entirely and is unsuitable for metrology-grade applications.

FAQ
What is the exact zener voltage range specified for HZ30BPTN-E?
The HZ30BPTN-E has a guaranteed zener voltage range of 30.2 V minimum to 31.6 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This corresponds to a nominal value of 30.9 V with ±2.3% tolerance. The voltage remains stable across its rated current range and is characterized using DC testing per the official Renesas datasheet REJ03G0182-0300 Rev.3.00.
Does HZ30BPTN-E support surface-mount assembly?
No, the HZ30BPTN-E uses a DO-35 glass axial-leaded package (JEITA code GRZZ0002ZB-A) designed exclusively for through-hole mounting. It is not compatible with reflow or wave soldering processes used for SMT components. For surface-mount alternatives, consider the MMBZ5262BLT1G-but note its higher dynamic resistance and lack of low-noise certification compared to HZ30BPTN-E.
What is the maximum allowable reverse current before breakdown for HZ30BPTN-E?
The HZ30BPTN-E specifies a maximum reverse leakage current (IR) of 1 μA at VR = 27.0 V and Ta = 25°C. This low leakage ensures minimal error contribution in high-impedance reference divider networks. Exceeding 27.0 V risks entering unregulated breakdown, and operation above the rated zener voltage should be avoided unless explicitly intended for clamping.
How does the noise performance of HZ30BPTN-E compare to standard Zener diodes?
The HZ30BPTN-E delivers approximately 1/3 to 1/10 the voltage noise of legacy HZ-series Zeners due to proprietary silicon planar processing and junction optimization. This reduction is measured across the 10 Hz–10 kHz bandwidth and directly improves signal-to-noise ratio in precision analog stages-such as those found in 18-bit ADC front-ends where HZ30BPTN-E is commonly deployed.
Can HZ30BPTN-E be used in automotive applications?
The HZ30BPTN-E is not qualified for automotive applications per Renesas documentation. It lacks AEC-Q101 stress testing and is rated for industrial temperature range only (Tstg = −55°C to +175°C, but operational derating begins above 25°C). For automotive-grade Zener references, consult Renesas' dedicated AEC-Q101 qualified portfolio-HZ30BPTN-E remains appropriate for industrial instrumentation, lab equipment, and commercial test systems.
