Product details
Overview
SMPC58ANHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the TRANSZORB® family, designed for high-energy surge protection on power and signal lines. It features a 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and 93.6 V maximum clamping voltage (VC) at 16 A IPPM - deployed in automotive sensor interfaces and industrial motor drive control circuits.
For engineers reviewing the SMPC58ANHM3/H datasheet, SMPC58ANHM3/H pinout, SMPC58ANHM3/H application, or SMPC58ANHM3/H equivalent, key selection criteria include AEC-Q101 qualification, TO-277A (SMPC) package compatibility with automated SMT placement, low-profile 1.1 mm height, and verified clamping performance under 10/1000 μs transients.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR range. Its low incremental surge resistance and fast response time enable effective suppression of inductive switching spikes and ESD events without latch-up or thermal runaway.
Designed for surface-mount use on FR4 PCBs with 2 oz copper, it delivers 1.25 W steady-state power dissipation at 25 °C ambient and supports junction temperatures up to +150 °C. The cathode-band-marked SMPC (TO-277A) package ensures correct polarity orientation during assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.0 V - maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 64.4 V / 71.2 V at 1.0 mA IT - defines reliable avalanche initiation threshold window |
| VC @ IPPM | 93.6 V at 16.0 A - clamped voltage during 10/1000 μs surge, limiting downstream stress |
| PPPM | 1500 W - peak transient power handling capability per standard waveform |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| Package | SMPC (TO-277A) - 3-terminal surface-mount package with 1.1 mm profile and J-STD-020 MSL Level 1 rating |
| Polarity | Unidirectional - protects against negative transients only; cathode band denotes terminal 1 |
Pinout & Package
SMPC58ANHM3/H uses the SMPC (TO-277A) package: a 3-terminal, low-profile surface-mount outline with anode terminals on pins 1 and 2, and cathode on pin 3. The cathode band identifies pin 3. Mounting pad layout conforms to JEDEC TO-277A mechanical drawings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | One of two parallel anode terminals; shares current path with Pin 2 to reduce parasitic inductance |
| Pin 2 (Anode) | Anode connection | Second anode terminal; enables higher surge current handling via dual-path layout |
| Pin 3 (Cathode) | Cathode connection | Marked by cathode band; connects to protected line's reference or ground return path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A-E3/5A | DO-214AC (SMA) package; 58 V VWM; 1500 W PPPM; not AEC-Q101 qualified | Lacks automotive qualification; lower thermal mass limits sustained surge duty cycle | Select when cost-sensitive industrial designs do not require automotive reliability validation |
| 1.5KE56A | DO-201AD axial package; 56 V VWM; 1500 W PPPM; through-hole mounting | Requires PCB real estate and wave-solder process; unsuitable for high-density SMT layouts | Choose for legacy board refreshes where footprint change is prohibited and manual assembly is acceptable |
Compared with SMAJ58A-E3/5A and 1.5KE56A, SMPC58ANHM3/H provides AEC-Q101 qualification, ultra-low 1.1 mm profile, and dual-anode construction for reduced dynamic impedance - making it optimal for new automotive and space-constrained industrial designs requiring automated SMT assembly.

FAQ
What is the breakdown voltage range for SMPC58ANHM3/H?
The SMPC58ANHM3/H has a specified breakdown voltage (VBR) range of 64.4 V to 71.2 V at 1.0 mA test current (IT), per the Vishay datasheet document 89116. This range ensures consistent avalanche triggering across production lots and supports robust design margining against overvoltage events in 58 V nominal systems.
Is SMPC58ANHM3/H qualified for automotive applications?
Yes, SMPC58ANHM3/H is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 17-Sep-2021. The "HM3" suffix explicitly denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction - validated for use in engine control, ADAS sensors, and body electronics where reliability under temperature cycling and vibration is critical.
What does the "H" in SMPC58ANHM3/H indicate?
The "H" in SMPC58ANHM3/H is the preferred package code denoting a 7-inch plastic tape-and-reel delivery format with 1500 units per reel. It is distinct from "I", which indicates 13-inch reels with 6500 units. Both "H" and "I" variants share identical electrical and mechanical specifications for SMPC58ANHM3/H.
What is the clamping voltage of SMPC58ANHM3/H at rated surge current?
The SMPC58ANHM3/H exhibits a maximum clamping voltage (VC) of 93.6 V at 16.0 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events, directly informing downstream IC voltage tolerance requirements.
Does SMPC58ANHM3/H have a bidirectional configuration?
No, SMPC58ANHM3/H is strictly unidirectional. Its polarity is marked by a cathode band on the package, and it conducts only during reverse-biased overvoltage conditions. Bidirectional variants (e.g., SMPC58A) exist in the same family but are separate orderable parts - SMPC58ANHM3/H is not interchangeable with them due to fundamental polarity and test-current differences.
