Product details
Overview
HZ16BPTN-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, with a nominal zener voltage of 16.0 V (min 15.7 V, max 16.5 V), dynamic resistance of 80 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C. It serves as a stable reference in low-drift power supply feedback paths and sensor biasing networks.
For engineers reviewing the HZ16BPTN-E datasheet, HZ16BPTN-E pinout, HZ16BPTN-E application, or HZ16BPTN-E equivalent, key selection criteria include its low-noise performance (≈1/3–1/10 of standard HZ series), tight VZ tolerance, DO-35 package compatibility, and temperature coefficient behavior across 15–17 V range.
Technical Context
The HZ16BPTN-E operates as a two-terminal shunt regulator using silicon planar junction technology, designed specifically for DC-stabilized references where noise floor and thermal drift are critical. Its zener voltage is specified under DC test conditions at IZ = 0.5 mA, with reverse current limited to ≤1 μA at VR = 15.0 V.
It exhibits a negative temperature coefficient in the 15–17 V range (≈−0.04 %/°C or −6.4 mV/°C), consistent with mid-voltage Zener operation, and maintains low dynamic impedance (80 Ω) to ensure minimal output variation under load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.7 V min / 16.5 V max at IZ = 0.5 mA - defines stable regulation window for feedback loop design |
| 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 thermal derating limit for PCB layout and heatsinking |
| Reverse Current (IR) | ≤1 μA at VR = 15.0 V - ensures minimal leakage error in high-impedance reference nodes |
| Junction Temperature (Tj) | −55°C to +175°C - supports operation in industrial and automotive under-hood environments |
| Package | DO-35 (JEITA GRZZ0002ZB-A) - industry-standard axial leaded package with orange body and navy-blue cathode band |
Pinout & Package
DO-35 glass axial package: cylindrical body (φD ≈ 2.0 mm, L ≈ 26.0 mm), orange-colored body with navy-blue cathode band. Mass ≈ 0.13 g. Lead spacing E = 4.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener anode connection point | Connected to regulated output node; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Zener cathode connection point | Typically tied to ground or common reference; forms shunt path for excess current |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener operation | Diode noise level ≈1/3–1/10 that of standard HZ series - reduces voltage reference jitter in ADC/DAC systems |
| Tight zener voltage tolerance | VZ = 15.7–16.5 V at 0.5 mA - enables accurate closed-loop regulation without trimming |
| Low dynamic impedance | rd ≤ 80 Ω - minimizes output voltage shift under varying load currents |
| High thermal stability | Tj rating up to 175°C - supports reliable operation in compact, thermally constrained layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | VZ = 14.0–15.4 V (nom. 15 V); rd = 14 Ω; Pd = 1 W; DO-41 package | Higher power, lower impedance, but wider VZ tolerance and higher noise than HZ16BPTN-E | Select when higher surge capability and lower rd outweigh low-noise requirement |
| BZX84-C16 | VZ = 15.3–16.7 V; rd = 40 Ω; Pd = 300 mW; SOT-23 package | Surface-mount, lower power, superior rd, but unconfirmed low-noise specification per datasheet | Select for space-constrained PCBs where reflow compatibility and footprint reduction are prioritized |
Compared with 1N4744A and BZX84-C16, the HZ16BPTN-E delivers uniquely low noise and tighter VZ control in a proven through-hole DO-35 package, making it optimal for metrology-grade analog references where spectral purity and long-term stability are non-negotiable.

FAQ
What is the exact zener voltage range for HZ16BPTN-E at 0.5 mA test current?
The HZ16BPTN-E has a guaranteed zener voltage range of 15.7 V minimum to 16.5 V maximum when tested at IZ = 0.5 mA under DC conditions. This 0.8 V span reflects the device's grade B tolerance within the HZ-L family and is verified per Renesas document REJ03G0182-0300 Rev.3.00. The HZ16BPTN-E is not rated for AC or pulsed testing in this specification.
Does HZ16BPTN-E have a documented noise performance specification?
Yes - the HZ-L Series datasheet explicitly states that its diode noise level is approximately 1/3 to 1/10 lower than the legacy HZ series. While no absolute nV/√Hz value is published, this comparative metric is confirmed across all HZ-L variants including the HZ16BPTN-E, and is attributable to optimized silicon planar junction processing. The HZ16BPTN-E inherits this low-noise advantage by design lineage.
What is the temperature coefficient of HZ16BPTN-E, and how is it derived?
The HZ16BPTN-E exhibits a temperature coefficient of approximately −0.04 %/°C (or −6.4 mV/°C) in the 15–17 V range, as shown in Figure 2 of the official datasheet. This value is extrapolated from the published γZ vs. VZ curve and applies directly to the HZ16BPTN-E due to its nominal 16 V rating. It is not a calculated average but a measured characteristic of the specific junction design.
Is HZ16BPTN-E compatible with lead-free soldering processes?
Yes - the DO-35 package of the HZ16BPTN-E is rated for standard lead-free reflow profiles per JEDEC J-STD-020. Its glass body and axial leads tolerate peak temperatures up to 260°C for ≤60 seconds. The HZ16BPTN-E has been qualified for RoHS-compliant assembly and carries no moisture sensitivity level (MSL) restriction due to hermetic glass construction.
Can HZ16BPTN-E be used in place of HZ16-2L?
Yes - HZ16BPTN-E is the updated ordering designation for what was previously labeled HZ16-2L in the same HZ-L Series datasheet (REJ03G0182-0300). Both share identical electrical specs, DO-35 packaging, orange body color, navy-blue cathode band, and Renesas part lineage. The HZ16BPTN-E is the current production version with no functional or parametric deviation from HZ16-2L.
