Product details
Overview
SMPC54ANHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the TRANSZORB® family, designed for high-energy surge protection on DC power rails and signal lines. It features a 54 V stand-off voltage (VWM), 60–66.3 V breakdown voltage (VBR), 1500 W peak pulse power (10/1000 μs), 17.2 A peak pulse current, and clamps to ≤87.1 V at rated surge. Used in automotive sensor interfaces and industrial power supplies to protect MOSFETs and ICs from inductive switching transients.
For engineers reviewing the SMPC54ANHM3/I datasheet, SMPC54ANHM3/I pinout, SMPC54ANHM3/I application, or SMPC54ANHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMPC (TO-277A) package dimensions, thermal resistance data, and real-world protection use cases - all confirmed from Vishay Document #89116 (Rev. 17-Sep-2021).
Technical Context
This device operates as a unidirectional avalanche diode with cathode-band polarity marking, optimized for fast response (<1 ns) to ESD and lightning-induced surges. Its low incremental surge resistance and tight VBR tolerance (±5%) ensure consistent clamping behavior across production lots.
Mounted on FR4 PCB with 2 oz copper, it delivers 1.25 W steady-state power dissipation at 25 °C and supports junction temperatures up to +150 °C. Thermal resistance junction-to-mount (RθJM) is 2.5–3.0 °C/W, enabling effective heat transfer when cathode is soldered to a heatsink pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VBR min/max | 60.0 / 66.3 V at 1.0 mA - ensures reliable avalanche conduction onset within tight tolerance band |
| VC @ IPPM | ≤87.1 V at 17.2 A - defines worst-case clamping voltage during 10/1000 μs surge, limiting protected circuit stress |
| PPPM | 1500 W - peak pulse power handling capability under standardized 10/1000 μs waveform |
| TJ max | +150 °C - enables operation in under-hood automotive and industrial environments |
| RθJM | 2.5–3.0 °C/W - quantifies thermal path efficiency from junction to mounting pad, critical for sustained surge duty cycles |
| MSL Level | Level 1 (J-STD-020) - supports lead-free reflow up to 260 °C peak without moisture-related failure |
Pinout & Package

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and Hall-effect sensors from load-dump and ISO 7637-2 pulses in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor signal line and chassis ground to clamp transients while preserving DC bias integrity. Use Value: With 54 V VWM and 87.1 V VC, it safeguards against 24 V system load-dump spikes without interfering with normal 5–12 V sensor output levels. | Use Scenario: Guarding microcontroller I/O pins and gate drivers in PLC output modules exposed to relay coil flyback and motor commutation noise. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V DC input rails, shunting surge energy directly to common ground before reaching regulation stage. Use Value: 1500 W PPPM rating and 17.2 A IPPM enable single-device protection of 24 V industrial supplies without derating or parallel staging. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
Use Scenario: Secondary-side surge suppression in USB-C PD adapters and AC/DC wall adapters subjected to conducted EMI and lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional clamping device on +5 V or +9 V output rails, positioned after DC-DC converter but before USB port controller. Use Value: 1.1 mm height allows integration into ultra-thin adapter PCBs; MSL Level 1 ensures compatibility with high-temperature lead-free assembly. | Use Scenario: Protecting Ethernet PHY interface circuits (e.g., RJ45 magnetics secondary side) from induced surges in building-wide LAN installations. IC Role / Device Role / Timing Role: TVS array element on differential pair lines (TX+/TX−), referenced to local ground plane with low-inductance layout. Use Value: Tight VBR tolerance (60–66.3 V) guarantees consistent clamping across temperature, preventing false triggering during nominal 48 V PoE voltage swings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ54A-M3/5A | Same VWM (54 V) and PPPM (1500 W), but SMA package (higher RθJA = 140 °C/W vs. 85 °C/W), no AEC-Q101 qualification | Not suitable for automotive under-hood use due to lower thermal performance and qualification gap | Select SMPC54ANHM3/I when board space permits and AEC-Q101 compliance or superior thermal management is required. |
| SMCJ54A-HM3 | Same VWM and AEC-Q101 qualification, but SMC package (7.11 × 6.22 mm), higher RθJM (5.0 °C/W), 10% larger footprint | Acceptable where PCB area is available and higher thermal mass is beneficial for repetitive surge events | Choose SMPC54ANHM3/I for compact designs needing minimal height (1.1 mm) and optimal junction-to-mount thermal path. |
Compared with SMAJ54A-M3/5A and SMCJ54A-HM3, SMPC54ANHM3/I offers the lowest profile (1.1 mm), best thermal resistance to mount (2.5 °C/W), and guaranteed AEC-Q101 qualification - making it the preferred choice for space- and thermal-critical automotive and industrial TVS deployments.

FAQ
What is the exact breakdown voltage range for SMPC54ANHM3/I?
The SMPC54ANHM3/I has a specified breakdown voltage (VBR) range of 60.0 V to 66.3 V at 1.0 mA test current, per Vishay Document #89116. This ±5.5% tolerance ensures predictable avalanche initiation across temperature and production lots, critical for repeatable clamping performance in automotive and industrial systems using the SMPC54ANHM3/I.
Is SMPC54ANHM3/I qualified for automotive applications?
Yes, SMPC54ANHM3/I is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Document #89116, Rev. 17-Sep-2021). The "HM3" suffix denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction - making SMPC54ANHM3/I suitable for under-hood and body-control module applications where reliability under thermal and mechanical stress is mandatory.
What does the "I" suffix mean in SMPC54ANHM3/I?
The "I" suffix in SMPC54ANHM3/I indicates the preferred packaging option: 13-inch diameter plastic tape and reel, with a base quantity of 6500 units. This differs from the "H" suffix (7-inch reel, 1500 units). Both share identical electrical and thermal specifications; the "I" variant supports high-volume automated assembly for production programs using the SMPC54ANHM3/I.
How does the SMPC (TO-277A) package improve thermal performance over SMA or SMC?
The SMPC (TO-277A) package used by SMPC54ANHM3/I achieves RθJM of 2.5–3.0 °C/W - significantly lower than SMA (≈140 °C/W) and SMC (≈5.0 °C/W) - due to its dual-anode, low-inductance layout and optimized thermal pad design. This allows SMPC54ANHM3/I to dissipate surge energy more efficiently into the PCB copper, enhancing reliability during repetitive transient events.
Can SMPC54ANHM3/I be used in bidirectional configurations?
No, SMPC54ANHM3/I is strictly unidirectional, as confirmed by its polarity marking (cathode band), datasheet designation "AN", and electrical characteristics table listing only VBR and VC for reverse-biased operation. For bidirectional protection, Vishay offers separate "CA" variants (e.g., SMPC54CANHM3/I); the SMPC54ANHM3/I must be oriented with cathode toward the protected line's reference potential.
