Product details
Overview
HZM3.3NB2TR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and digital supply rails. It delivers a nominal zener voltage of 3.3 V (min 3.25 V, max 3.50 V) at 5 mA test current, with dynamic resistance of 130 Ω, power dissipation of 200 mW, and operates within –55°C to +150°C storage temperature range - commonly used in voltage reference circuits for microcontroller reset supervision and sensor biasing.
For engineers reviewing the HZM3.3NB2TR-E datasheet, HZM3.3NB2TR-E pinout, HZM3.3NB2TR-E application, or HZM3.3NB2TR-E equivalent, key selection criteria include its MPAK package footprint, grade-B2 tolerance band, 130 Ω dynamic impedance at 5 mA, thermal coefficient behavior near zero crossing (~0 mV/°C), and suitability for high-density SMT designs requiring stable 3.3 V regulation under low-current conditions.
Technical Context
The HZM3.3NB2TR-E employs a silicon epitaxial planar junction structure optimized for stable reverse-breakdown characteristics. Its zener voltage is specified at IZ = 5 mA with ±0.125 V tolerance (3.25–3.50 V), and exhibits a temperature coefficient near zero (≈0 mV/°C) per Fig.2 of the datasheet, making it suitable for applications where thermal drift must be minimized.
It operates as a two-terminal passive voltage reference with no control logic or active circuitry. The device is rated for Pd = 200 mW at Ta = 25°C, derating linearly above 25°C per Fig.3, and features non-connected (NC) pin 1 to enable three-terminal layout compatibility while maintaining dual-terminal electrical function.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 3.25–3.50 V at IZ = 5 mA - defines tight regulation window for 3.3 V rail monitoring and clamping. |
| Dynamic Resistance rd | 130 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity. |
| Power Dissipation Pd | 200 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating applies. |
| Junction Temperature Tj | 150°C max - defines upper thermal limit for reliable long-term operation in enclosed environments. |
| Reverse Current IR | 20 µA max at VR = 1.0 V - indicates leakage level critical for low-power standby circuits. |
| Package | MPAK (JEITA PLSP0003ZC-A) - 3-pin SMT package with 0.65 mm lead pitch, optimized for automated placement and high board density. |
Pinout & Package
MPAK package: 3-terminal surface-mount outline with 1.0 mm × 1.3 mm body, 0.65 mm lead pitch, and 0.1–0.26 mm terminal thickness. Pin 1 is NC (no internal connection), enabling layout flexibility without functional impact.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (NC) | Unused terminal; electrically isolated - allows PCB routing flexibility and avoids accidental shorting. |
| 2 | Anode | Forward-biased terminal; connects to lower-potential node in reverse-bias stabilization configuration. |
| 3 | Cathode | Zener breakdown terminal; connects to higher-potential node and serves as regulated output reference point. |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B2 zener voltage tolerance | ±0.125 V at 3.3 V - enables tighter system-level voltage margin control than standard-grade Zeners. |
| Low-temperature-coefficient operation | ≈0 mV/°C near 3.3 V (per Fig.2) - minimizes drift across industrial temperature range (–40°C to +85°C). |
| MPAK surface-mount package | 0.65 mm pitch, 1.0 × 1.3 mm footprint - supports high-density PCB layouts and high-speed pick-and-place assembly. |
| Pulse-tested characterization | VZ, rd, IR measured with 40 ms pulse - ensures parameter stability under transient loading typical in power-supply startup. |
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 |
|---|---|---|---|
| MMSZ4685T1G | Zener voltage 3.3 V (±5%), rd = 95 Ω, SOD-123 package, Pd = 500 mW | Higher power rating but wider tolerance; lacks NC pin for layout flexibility | Preferred when higher surge energy absorption is required and tighter VZ tolerance is not critical |
| BZX84-C3V3 | Zener voltage 3.3 V (±5%), rd = 90 Ω, SOT-23 package, Pd = 350 mW | Standard-grade tolerance, no NC pin, smaller 1.3 × 1.75 mm footprint | Selected for cost-sensitive consumer designs where B2-grade precision is unnecessary |
Compared with MMSZ4685T1G and BZX84-C3V3, the HZM3.3NB2TR-E offers superior voltage tolerance (±0.125 V vs. ±5%) and a dedicated NC pin for routing optimization, though at lower power rating - making it ideal for space-constrained industrial systems demanding precision over raw surge capacity.

FAQ
What is the exact zener voltage range for HZM3.3NB2TR-E at 5 mA?
The HZM3.3NB2TR-E has a guaranteed zener voltage range of 3.25 V to 3.50 V when tested at IZ = 5 mA and Ta = 25°C, corresponding to its Grade-B2 specification. This ±0.125 V tolerance is tighter than standard-grade Zeners and supports precision reference applications where minimal voltage deviation is critical. The HZM3.3NB2TR-E maintains this specification across its qualified operating temperature range.
Does HZM3.3NB2TR-E require external biasing or support active control?
No, the HZM3.3NB2TR-E is a passive two-terminal device with no active circuitry or control interface. It functions solely as a reverse-biased voltage reference, requiring only a series current-limiting resistor to operate. Pin 1 is NC (no connection), confirming that the HZM3.3NB2TR-E uses only pins 2 (anode) and 3 (cathode) for electrical operation - no external biasing, enable signals, or feedback paths are needed or supported.
What is the thermal coefficient behavior of HZM3.3NB2TR-E near 3.3 V?
Per Figure 2 in the R07DS0358EJ0600 datasheet, the HZM3.3NB2TR-E exhibits a zener voltage temperature coefficient (γZ) near 0 mV/°C at 3.3 V, meaning its breakdown voltage remains exceptionally stable across temperature. This zero-crossing characteristic minimizes drift in applications like precision references and sensor biasing, where even ±1 mV/°C drift would degrade accuracy over industrial temperature ranges. The HZM3.3NB2TR-E leverages this property inherently - no calibration or compensation is required.
Can HZM3.3NB2TR-E replace standard 3.3 V Zener diodes in existing SOT-23 layouts?
No - the HZM3.3NB2TR-E uses the MPAK (PLSP0003ZC-A) package, which differs mechanically from SOT-23: it measures 1.0 × 1.3 mm with 0.65 mm lead pitch and includes an NC pin, whereas SOT-23 is 1.3 × 1.75 mm with 0.95 mm pitch and only two active terminals. Direct PCB replacement requires footprint redesign. The HZM3.3NB2TR-E is not a drop-in substitute for SOT-23 Zeners, though its electrical performance may justify layout revision in new designs prioritizing precision and density.
Is HZM3.3NB2TR-E suitable for automotive applications?
The HZM3.3NB2TR-E is classified as a "Standard" quality grade device per Renesas' documentation, intended for computers, office equipment, communications gear, and industrial robots - not for automotive, medical life-support, or aerospace use. It does not meet AEC-Q200 stress testing requirements. For automotive applications requiring qualification, designers should select Renesas' "High Quality" or "Specific" grade alternatives explicitly rated for transportation systems. The HZM3.3NB2TR-E remains appropriate for industrial and commercial embedded systems.
