Product details
Overview
SMPC54AN-M3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the TRANSZORB® family, designed for high-energy surge clamping on power 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 87.1 V maximum clamping voltage at IPPM - deployed to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMPC54AN-M3/H datasheet, SMPC54AN-M3/H pinout, SMPC54AN-M3/H application, or SMPC54AN-M3/H equivalent, this page delivers verified electrical parameters, TO-277A package details, AEC-Q101 qualification status, thermal resistance values, and real-world protection use cases - all aligned with Vishay Document #89116 (Rev. 17-Sep-2021).
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified breakdown range (60.0–66.3 V). Its low incremental surge resistance and fast response time enable effective suppression of transients from inductive load switching and ESD events.
Mounted on FR4 PCB with 2 oz copper, it delivers 1.25 W steady-state power dissipation at 25 °C and supports junction temperatures from –55 °C to +150 °C. Thermal resistance is rated at RθJA ≤ 100 °C/W and RθJM ≤ 3 °C/W, confirming suitability for thermally constrained surface-mount applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 60.0 / 66.3 V at 1.0 mA - defines reliable avalanche initiation window under standardized test conditions |
| VC at IPPM | 87.1 V - clamped voltage during 17.2 A 10/1000 μs surge, directly limiting stress on downstream components |
| PPPM | 1500 W - peak pulse power handling capability per standard 10/1000 μs waveform, critical for IEC 61000-4-5 compliance margin |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive and industrial environments |
| RθJA | ≤ 100 °C/W - thermal resistance from junction to ambient on standard FR4 layout, guiding heatsinking requirements |
| MSL Level | Level 1 (J-STD-020) - supports lead-free reflow up to 260 °C peak without moisture-induced failure |

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power rails against load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp surges above 54 V while remaining inert during normal operation. Use Value: Limits peak voltage to 87.1 V during 1500 W surges, preventing damage to 60 V-rated input regulators and LDOs in body control modules. |

IC Role / Device Role / Timing Role: Placed between gate and source terminals to clamp dv/dt-induced overshoot exceeding 54 V. Use Value: Fast response and low clamping voltage prevent unintended turn-on and gate oxide overstress in 650 V Si devices. |
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-E3/5A (Vishay) | Same VWM (54 V) and VC (87.1 V), but SMA package (higher RθJA ≈ 150 °C/W); 400 W PPPM vs. 1500 W | Limited to lower-energy transients; unsuitable for load dump or IEC 61000-4-5 Level 4 | Select only where board space is extremely limited and surge energy remains below 400 W |
| TPSMD54A (Texas Instruments) | Identical VWM (54 V), slightly higher VC (89.2 V), same 1500 W rating; TO-277A package; no AEC-Q101 certification | Acceptable for industrial use but requires additional qualification for automotive deployment | Prefer SMPC54AN-M3/H when AEC-Q101 compliance and traceable Vishay supply chain are mandatory |
Compared with SMAJ54A-E3/5A and TPSMD54A, SMPC54AN-M3/H uniquely combines 1500 W surge capacity, AEC-Q101 qualification, and TO-277A thermal performance - making it the optimal choice for automotive power domain protection where reliability and energy handling are co-critical.

FAQ
What is the clamping voltage of SMPC54AN-M3/H at its rated peak pulse current?
The SMPC54AN-M3/H has a maximum clamping voltage (VC) of 87.1 V when subjected to its rated peak pulse current (IPPM) of 17.2 A under the standard 10/1000 μs waveform. This value is measured with the cathode mounted on a heatsink per Vishay Document #89116, ensuring realistic worst-case system protection margins for the SMPC54AN-M3/H.
Is SMPC54AN-M3/H qualified for automotive applications?
Yes, SMPC54AN-M3/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code structure ("AN" suffix and M3/H packaging). It meets automotive reliability requirements including temperature cycling, mechanical shock, and humidity testing - making SMPC54AN-M3/H suitable for under-hood and chassis-mounted electronic control units.
What does the "H" suffix indicate in SMPC54AN-M3/H?
The "H" suffix in SMPC54AN-M3/H specifies the preferred package code for 7-inch diameter plastic tape and reel delivery, containing 1500 units per reel. This packaging format is optimized for high-volume SMT assembly and aligns with JEDEC-standard handling - a key detail for production planning of SMPC54AN-M3/H.
How does SMPC54AN-M3/H differ from SMPC54A-M3?
SMPC54AN-M3/H is AEC-Q101 qualified and uses an enhanced construction validated for automotive use, whereas SMPC54A-M3 is industrial-grade only. Both share identical electrical specs (VWM = 54 V, VC = 87.1 V), but SMPC54AN-M3/H undergoes additional stress testing and lot traceability - critical for SMPC54AN-M3/H deployment in safety-relevant automotive systems.
What is the thermal resistance junction-to-ambient for SMPC54AN-M3/H?
The maximum thermal resistance junction-to-ambient (RθJA) for SMPC54AN-M3/H is 100 °C/W when mounted on a standard FR4 PCB with 2 oz copper, per JEDEC 51-2A. This value guides thermal design for sustained power dissipation and confirms that SMPC54AN-M3/H remains within safe operating limits up to 1.25 W at 25 °C ambient.
