Product details
Overview
HZM2.7NB2TR-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 2.7 V (min 2.65 V, max 2.90 V at 5 mA), dynamic resistance of 110 Ω, and power dissipation rating of 200 mW in the MPAK surface-mount package.
For engineers reviewing the HZM2.7NB2TR-E datasheet, HZM2.7NB2TR-E pinout, HZM2.7NB2TR-E application, or HZM2.7NB2TR-E equivalent, this device serves as a compact, temperature-stable shunt regulator for sensor biasing, ADC reference trimming, and low-current power rail clamping where tight voltage tolerance and minimal thermal drift are required.
Technical Context
The HZM2.7NB2TR-E operates as a two-terminal shunt regulator, maintaining stable output voltage across its cathode–anode terminals under reverse-biased conditions. Its zener breakdown mechanism relies on controlled avalanche and tunneling effects optimized for 2.7 V operation, with specified test current of 5 mA and maximum reverse current of 120 µA at 1.0 V.
It features a negative temperature coefficient of approximately –0.04 mV/°C near 2.7 V (per Fig.2), enabling predictable drift compensation in mixed-signal systems. The device is rated for junction temperatures up to 150°C and storage from –55°C to +150°C, supporting industrial-grade reliability without derating below 70°C ambient.

|---|---|
Use Scenario: Providing stable excitation voltage to RTD or thermistor bridges in HVAC controllers operating from 3.3 V rails. IC Role / Device Role / Timing Role: Shunt voltage reference connected between bridge top node and ground, sinking excess current via series resistor. Use Value: Maintains <±1% bridge voltage stability over –40°C to +85°C ambient due to predictable –0.04 mV/°C drift and low rd. |
Use Scenario: Clamping input voltage to 2.7 V for 12-bit SAR ADCs in portable data loggers powered by coin-cell batteries. IC Role / Device Role / Timing Role: Overvoltage protection element placed at ADC analog input, limiting signal swing during transient events. Use Value: Prevents ADC saturation with 120 µA leakage at 1.0 V, minimizing quiescent current drain while ensuring fast response to >2.7 V transients. |
| Microcontroller Reset Circuit Reference | Industrial IO Module Voltage Clamp |
Use Scenario: Generating threshold voltage for external reset supervisor ICs monitoring 3.3 V supply in PLC I/O cards. IC Role / Device Role / Timing Role: Precision shunt reference feeding comparator input; paired with resistor divider to set exact reset threshold. Use Value: Enables ±15 mV reset threshold accuracy (vs. typical ±50 mV with generic Zeners), reducing false resets in noisy factory environments. |
Use Scenario: Protecting 24 V digital input channels against ESD and surge-induced overvoltage in DIN-rail mounted automation controllers. IC Role / Device Role / Timing Role: Secondary clamp stage downstream of TVS diodes, absorbing residual energy below 3 V to safeguard logic-level translators. Use Value: Limits clamped voltage to ≤2.9 V with 110 Ω rd, preventing latch-up in 3.3 V interface ICs during 1 kV EFT bursts. |
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-C2V7LT1G | 2.7 V ±5% (2.57–2.84 V), SOT-23, 350 mW Pd, rd = 90 Ω | Higher power rating but looser tolerance; requires layout change due to different footprint | Select when higher surge energy absorption is needed and ±5% regulation tolerance is acceptable |
| MMSZ4683T1G | 2.7 V ±5%, SOD-123, 500 mW Pd, rd = 100 Ω, Tj = 150°C | Larger package (SOD-123 vs. MPAK), same temp rating, slightly lower rd | Choose for legacy designs using SOD-123 footprints or where higher power margin is prioritized over board space |
Compared with BZX84-C2V7LT1G and MMSZ4683T1G, the HZM2.7NB2TR-E offers tighter ±0.125 V tolerance and MPAK's smaller footprint-critical for space-constrained sensor nodes-while trading off absolute power rating for superior regulation precision at low currents.

FAQ
What is the zener voltage tolerance of HZM2.7NB2TR-E?
The HZM2.7NB2TR-E has a zener voltage range of 2.65 V to 2.90 V at 5 mA test current, corresponding to Grade B2 binning. This ±0.125 V tolerance provides tighter regulation than standard B-grade parts (±0.25 V) and supports precision reference design without post-manufacturing calibration. The specification is guaranteed per R07DS0358EJ0600 Rev.6.00, page 2.
Does HZM2.7NB2TR-E have a no-connect pin, and how should it be handled?
Yes, Pin 1 of the HZM2.7NB2TR-E is designated NC (No Connect) and must remain unconnected on the PCB. It is electrically isolated and serves only mechanical anchoring; routing traces or soldering to Pin 1 may induce stress fractures or parasitic coupling. The official pin arrangement diagram (page 1) confirms this configuration for all HZM-N Series devices in MPAK packaging.
What is the maximum allowable reverse current for HZM2.7NB2TR-E at 1.0 V?
The maximum reverse current (IR) for HZM2.7NB2TR-E is 120 µA when reverse voltage (VR) is applied at 1.0 V, as specified in the Electrical Characteristics table (page 2). This low leakage ensures minimal quiescent current draw in battery-powered applications such as wireless sensor nodes, where standby current budgets are sub-µA.
Can HZM2.7NB2TR-E operate reliably at 125°C ambient temperature?
Yes, HZM2.7NB2TR-E supports ambient temperatures up to 125°C without derating, provided junction temperature remains ≤150°C. With its 200 mW power rating and MPAK package thermal resistance (estimated ~300°C/W), it sustains stable 2.7 V regulation in industrial motor drives and automotive cabin modules-confirmed by Absolute Maximum Ratings (page 2) and Fig.3 derating curve.
Is the MPAK package of HZM2.7NB2TR-E compatible with standard reflow profiles?
Yes, the MPAK package (JEITA PLSP0003ZC-A) used by HZM2.7NB2TR-E complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard Pb-free reflow profiles (peak 260°C, 20–40 sec). Its 0.65 mm lead pitch and coplanarity <0.1 mm ensure reliable solder joint formation in high-speed SMT lines, as validated in Renesas package documentation.
