Product details
Overview
HZM3.0NB1TR-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 3.10 V to 3.35 V at 5 mA, dynamic resistance of ≤120 Ω, power dissipation of 200 mW, and junction temperature rating up to 150 °C - deployed in industrial sensor signal conditioning and microcontroller reset circuitry.
For engineers reviewing the HZM3.0NB1TR-E datasheet, HZM3.0NB1TR-E pinout, HZM3.0NB1TR-E application, or HZM3.0NB1TR-E equivalent, key selection criteria include zener voltage tolerance (±3.5% at 3.225 V nominal), low dynamic impedance for stable regulation under varying load, MPAK surface-mount package compatibility with high-density PCB layouts, and thermal performance across –55 °C to +150 °C operating range.
Technical Context
The HZM3.0NB1TR-E operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its specified zener breakdown threshold. Its silicon epitaxial planar construction ensures tight voltage distribution and low leakage.
It is characterized at 5 mA test current with pulse testing (Pw = 40 ms) to minimize self-heating effects, and exhibits a temperature coefficient near zero (–0.01 to +0.02 mV/°C) within the 3.0 V zener range - critical for temperature-insensitive reference designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.10 V to 3.35 V at IZ = 5 mA - defines precise regulation point for low-voltage reference rails. |
| Dynamic Resistance (rd) | ≤120 Ω at IZ = 5 mA - ensures minimal output voltage shift under load transients. |
| Power Dissipation (Pd) | 200 mW - supports continuous operation in compact SMT layouts without forced cooling. |
| Junction Temperature (Tj) | –55 °C to +150 °C - enables use in extended-temperature industrial and automotive under-hood environments. |
| Reverse Current (IR) | ≤50 μA at VR = 1.0 V - guarantees low standby leakage in battery-backed systems. |
| Package | MPAK (PLSP0003ZC-A) - 3-pin surface-mount package with 0.65 mm lead pitch, optimized for automated assembly. |
Pinout & Package
MPAK package (JEITA code PLSP0003ZC-A), 3-terminal surface-mount device with exposed cathode pad for thermal enhancement. Dimensions: 2.7–3.1 mm × 1.35–1.65 mm × 0.95 mm max height; mass ≈ 0.011 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected terminal - must remain floating; no routing or soldering required. |
| 2 | Anode | Forward-biased terminal; connected to lower-potential node in shunt regulation configuration. |
| 3 | Cathode | Zener-active terminal; connected to regulated output node and current-limiting resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B1 voltage tolerance | ±3.5% (3.10–3.35 V) - enables tighter system-level voltage margin control vs. standard-grade Zeners. |
| Pulse-tested characterization | 40 ms pulse width - eliminates thermal drift during parameter validation, ensuring real-world regulation accuracy. |
| Low-temperature-coefficient design | –0.01 to +0.02 mV/°C - minimizes drift over industrial temperature range, supporting stable references. |
| High-density MPAK footprint | 2.9 mm × 1.5 mm body - saves >40% board area vs. traditional SOT-23 while maintaining thermal robustness. |
Applications

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 |
|---|---|---|---|
| MMSZ4684T1G | Zener voltage 3.3 V ±5%, Pd = 350 mW, SOD-123 package, rd = 90 Ω | Higher power rating but wider voltage tolerance and larger footprint - suitable where layout space allows and tighter regulation is not required. | Select when higher surge energy handling is needed and ±5% VZ tolerance is acceptable. |
| BZX84-C3V3 | Zener voltage 3.3 V ±5%, Pd = 300 mW, SOT-23 package, rd = 95 Ω | Same 3-pin SMT form factor but lacks NC pin; tighter thermal resistance due to metalized backside - better for thermally constrained designs. | Choose for cost-sensitive volume production where grade-B1 tolerance is not mandatory and thermal performance is prioritized. |
Compared with MMSZ4684T1G and BZX84-C3V3, the HZM3.0NB1TR-E delivers superior voltage accuracy (±3.5% vs. ±5%) in a smaller MPAK footprint, though at lower power rating; it is optimal where precision and board space are critical, not raw power handling.

FAQ
What is the exact zener voltage range for HZM3.0NB1TR-E at 5 mA?
The HZM3.0NB1TR-E has a guaranteed zener voltage range of 3.10 V to 3.35 V when tested at IZ = 5 mA and Ta = 25 °C, corresponding to Grade B1 tolerance per Renesas datasheet R07DS0358EJ0600. This ±3.5% window ensures predictable regulation behavior in precision low-voltage reference designs.
Does HZM3.0NB1TR-E require external current limiting, and what is the recommended value?
Yes, HZM3.0NB1TR-E requires an external series current-limiting resistor to set operating current within its safe range. For stable regulation at 5 mA with a 5 V supply, a 390 Ω ±1% resistor provides ~4.9 mA bias while staying within the 200 mW power limit - verified using the absolute maximum ratings and electrical characteristics in the official datasheet.
Is Pin 1 of HZM3.0NB1TR-E internally connected, and how should it be handled on the PCB?
No - Pin 1 of HZM3.0NB1TR-E is designated "NC" (No Connect) and is internally unconnected. It must remain electrically floating: no trace routing, no solder mask opening, and no thermal pad connection. Leaving it unconnected prevents parasitic coupling and ensures compliance with Renesas' validated MPAK layout guidelines.
How does the temperature coefficient of HZM3.0NB1TR-E impact long-term reference stability?
The HZM3.0NB1TR-E exhibits a temperature coefficient between –0.01 mV/°C and +0.02 mV/°C across its 3.0 V zener range, resulting in <±0.3 mV drift over –40 °C to +85 °C. This translates to <0.01% full-scale error in 3.3 V reference applications - making it suitable for industrial-grade analog signal chains where passive compensation suffices.
Can HZM3.0NB1TR-E replace older HZM3.0N variants without layout changes?
Yes - HZM3.0NB1TR-E shares identical MPAK (PLSP0003ZC-A) package dimensions, pinout, and solder footprint with all HZM3.0N-series variants including HZM3.0NB2TR-E and HZM3.0NBTRE. The only differences are tighter Grade B1 voltage tolerance and updated tape-and-reel packaging; no PCB redesign is needed for drop-in replacement.
