Product details
Overview
HZM9.1NB3JTR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, with a nominal zener voltage of 9.15 V to 9.55 V at 5 mA test current, 6.0 Ω dynamic resistance, and 200 mW power dissipation in the MPAK (SC-59A) surface-mount package.
For engineers reviewing the HZM9.1NB3JTR-E datasheet, HZM9.1NB3JTR-E pinout, HZM9.1NB3JTR-E application, or HZM9.1NB3JTR-E equivalent, this part supports stable voltage reference design in space-constrained industrial sensors, power supply feedback loops, and analog signal conditioning where ±4% zener tolerance, low temperature coefficient (≈+0.03 mV/°C), and high-density SMT assembly are required.
Technical Context
The HZM9.1NB3JTR-E operates as a two-terminal shunt regulator, maintaining a stable reverse-biased breakdown voltage across its cathode–anode terminals under controlled current conditions. Its epitaxial planar structure ensures tight VZ distribution and low dynamic impedance (rd = 6.0 Ω at IZ = 5 mA).
It is rated for 200 mW maximum power dissipation at Ta = 25°C, with junction temperature limited to 150°C and storage range from –55°C to +150°C. The device exhibits a positive zener voltage temperature coefficient of approximately +0.03 mV/°C near 9.1 V, confirmed in Figure 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.15 V to 9.55 V at IZ = 5 mA - defines stable regulation point for feedback or reference use |
| Dynamic Resistance (rd) | 6.0 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous thermal budget on PCB |
| Reverse Current (IR) | ≤2 μA at VR = 7.0 V - ensures minimal leakage before breakdown onset |
| Junction Temperature (Tj) | 150°C maximum - constrains thermal design margin for long-term reliability |
| Package | MPAK (SC-59A), JEITA code PLSP0003ZC-A - enables 0.8 mm × 1.0 mm footprint and automated placement |
| Temperature Coefficient (γZ) | +0.03 mV/°C near 9.1 V - enables predictable drift compensation in precision references |
Pinout & Package
MPAK (SC-59A) surface-mount package: 3-terminal plastic molded case with gull-wing leads; dimensions per Page 6: D = 2.7–3.1 mm, E = 1.35–1.65 mm, L = 0.65 mm, mass ≈ 0.011 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Anode | Forward-biased terminal; connects to lower-potential node in shunt regulation configuration |
| 3 | Cathode | Breakdown terminal; connects to regulated voltage node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|

| Low Dynamic Impedance | 6.0 Ω at 5 mA - minimizes output voltage variation under load transients |
| High-Density MPAK Package | 0.8 mm × 1.0 mm footprint - supports miniaturized PCB layouts and high-speed pick-and-place |
| Controlled Temperature Drift | +0.03 mV/°C near 9.1 V - enables stable operation across –25°C to +85°C ambient ranges |
| Low Leakage Performance | ≤2 μA at 7.0 V reverse bias - reduces error in high-impedance reference divider networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1,115 | Same nominal VZ (9.1 V), SOT-23 package, 350 mW Pd, ±5% tolerance, rd = 10 Ω | Higher power rating but larger footprint; less suitable for ultra-dense layouts | Select when higher surge capability or legacy SOT-23 compatibility is required |
| MMSZ5240B-TP | VZ = 10 V (min 9.5 V, max 10.5 V), SOD-123, 500 mW Pd, rd = 17 Ω | 10 V nominal rating shifts reference point; higher rd degrades regulation under load | Choose only if system tolerates 10 V reference and requires higher power handling |
Compared with BZX84-C9V1,115 and MMSZ5240B-TP, the HZM9.1NB3JTR-E offers superior regulation stability (6.0 Ω rd) and compact MPAK footprint, making it optimal for space-constrained, precision-referenced designs where exact 9.1 V stabilization is critical.

FAQ
What is the zener voltage range for HZM9.1NB3JTR-E at 5 mA test current?
The HZM9.1NB3JTR-E has a guaranteed zener voltage range of 9.15 V to 9.55 V when tested at IZ = 5 mA, corresponding to Grade B3 tolerance per the R07DS0358EJ0600 datasheet. This 4.4% spread ensures predictable regulation behavior in feedback and reference circuits where HZM9.1NB3JTR-E is deployed.
Is Pin 1 of HZM9.1NB3JTR-E electrically connected internally?
No - Pin 1 of HZM9.1NB3JTR-E is designated NC (No Connect) and is not bonded internally. It must be left unconnected on the PCB; routing or soldering to Pin 1 may cause mechanical stress or unintended coupling but will not affect electrical performance of the HZM9.1NB3JTR-E.
What is the maximum allowable power dissipation for HZM9.1NB3JTR-E at 70°C ambient temperature?
Per Figure 3 in the HZM-N Series datasheet, the HZM9.1NB3JTR-E derates linearly from 200 mW at 25°C to approximately 140 mW at 70°C ambient. This reflects its thermal resistance profile in the MPAK package and must be observed to maintain junction temperature ≤150°C during continuous operation of the HZM9.1NB3JTR-E.
Does HZM9.1NB3JTR-E meet RoHS compliance requirements?
Yes - HZM9.1NB3JTR-E is manufactured by Renesas Electronics in accordance with EU RoHS Directive 2011/65/EU, as confirmed in the product's environmental compliance documentation and packaging markings. All homogeneous materials in the HZM9.1NB3JTR-E device comply with restricted substance thresholds.
How does the temperature coefficient of HZM9.1NB3JTR-E compare to other 9.1 V Zener diodes?
The HZM9.1NB3JTR-E exhibits a measured temperature coefficient of approximately +0.03 mV/°C near its 9.1 V operating point (Figure 2, R07DS0358EJ0600), which is significantly lower than typical 9.1 V Zeners with coefficients >+2 mV/°C. This makes the HZM9.1NB3JTR-E especially suitable for stable reference applications where thermal drift must be minimized.
