Product details
Overview
VTVS52ASMF-HM3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection of low-voltage DC lines. It features a 52.2 V maximum stand-off voltage (VRWM), 58.9–65.1 V reverse breakdown voltage (VBR) at 1 mA, 89 A peak pulse current (IPPM) under 10/1000 μs waveform, and clamps to ≤89 V at rated current - deployed in automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS52ASMF-HM3-08 datasheet, VTVS52ASMF-HM3-08 pinout, VTVS52ASMF-HM3-08 application, or VTVS52ASMF-HM3-08 equivalent, key selection criteria include its ±5 % VBR tolerance, 242 pF typical junction capacitance at 0 V, AEC-Q101 qualification option, halogen-free construction, and compatibility with SOD-123W footprint constraints.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified breakdown range (58.9–65.1 V). Its low-noise fast-response architecture achieves clamping within nanoseconds, enabling effective suppression of IEC 61000-4-2 ±30 kV contact/air discharge events.
Thermal resistance is rated at 20 K/W (junction-to-lead, infinite heat sink), supporting operation up to +175 °C junction temperature. The SMF package's 1.08 mm height and 3.9 × 1.9 mm outline ensure compatibility with space-constrained PCB layouts while maintaining robust solder joint reliability under wave and reflow processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform; defines maximum transient energy absorption capability) |
| Stand-off Voltage (VRWM) | 52.2 V (maximum continuous reverse voltage before significant leakage; sets operating margin for 48 V systems) |
| Breakdown Voltage (VBR) | 58.9–65.1 V at IT = 1 mA (avalanche initiation range; ±5 % tolerance ensures predictable turn-on behavior) |
| Clamping Voltage (VC) | ≤89 V at IPPM = 89 A (voltage seen by protected circuit during worst-case surge; critical for downstream IC survival) |
| Junction Capacitance | 242 pF at VR = 0 V, f = 1 MHz (impacts high-speed signal integrity; suitable for <10 Mbps data lines) |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 (meets automotive and industrial immunity requirements) |
| Operating Temperature | −55 °C to +175 °C (enables deployment in under-hood automotive and industrial environments) |

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 (Vishay) | Same 58 V VBR range but SMA package (DO-214AC); 400 W rating; 200 pF capacitance | Larger footprint (4.5 × 2.7 mm) and 2.3 mm height limit use in ultra-thin assemblies | Select when legacy SMA layout exists or higher thermal mass is needed for repetitive surge duty cycles |
| TPSMD58A (Texas Instruments) | 58 V VBR, 400 W, DO-214AB package; 220 pF; ±5 % tolerance; not AEC-Q101 qualified | No automotive qualification; slightly lower clamping (85 V) but tighter thermal resistance (15 K/W) | Prefer for cost-sensitive industrial designs where AEC-Q101 is not mandated and lower VC improves margin |
Compared with VTVS52ASMF-HM3-08, SMAJ58A-E3/5A offers greater thermal mass in a larger package, while TPSMD58A trades automotive qualification for marginally better clamping and thermal performance - making VTVS52ASMF-HM3-08 optimal for space-constrained, automotive-grade 48 V rail protection.

FAQ
What is the exact breakdown voltage range for VTVS52ASMF-HM3-08?
The VTVS52ASMF-HM3-08 has a reverse breakdown voltage (VBR) range of 58.9 V to 65.1 V at IT = 1 mA and TJ = 25 °C, with ±5 % tolerance as indicated by the "A" suffix in the part number. This range ensures consistent clamping behavior across production lots and temperature extremes up to +175 °C.
Is VTVS52ASMF-HM3-08 qualified to AEC-Q101?
VTVS52ASMF-HM3-08 itself is not automatically AEC-Q101 qualified - qualification depends on the environmental and quality code suffix. The "HM3-08" suffix indicates halogen-free, RoHS-compliant, lead-free terminations and 3 k per 7″ reel packaging. An AEC-Q101-qualified version would carry an "H" prefix (e.g., VTVS52ASMF-HM3-08 with additional qualification marking), confirmed via Vishay's official datasheet revision history.
What does the "HM3-08" suffix mean in VTVS52ASMF-HM3-08?
In VTVS52ASMF-HM3-08, "H" denotes halogen-free construction, "M3" specifies lead-free, RoHS-compliant tin-plated terminations, and "-08" indicates 3,000 units per 7″ reel (8 mm tape, MOQ = 30,000). This full suffix confirms compliance with JEDEC MSL level 1, J-STD-020 reflow profile (peak 260 °C), and Vishay's material categorization standard.
Can VTVS52ASMF-HM3-08 be used in bidirectional protection circuits?
No - VTVS52ASMF-HM3-08 is a unidirectional TVS diode, intended for DC line protection where polarity is fixed. Bidirectional operation requires symmetrical devices like the VTVS52BSMF series. Using this part in AC or reversible-polarity applications risks failure due to forward conduction during negative half-cycles.
What is the thermal resistance (RthJL) of VTVS52ASMF-HM3-08?
The thermal resistance from junction to lead (RthJL) for VTVS52ASMF-HM3-08 is 20 K/W when mounted on an infinite heat sink, as specified in Vishay's absolute maximum ratings table. This value enables accurate thermal modeling for surge duty cycle derating and ensures safe operation at 175 °C junction temperature under defined PCB copper area conditions.
