Product details
Overview
SMA5J6.0AHE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on DC power rails and signal lines. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), 48.5 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is AEC-Q101 qualified and used in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMA5J6.0AHE3/61 datasheet, SMA5J6.0AHE3/61 pinout, SMA5J6.0AHE3/61 application, or SMA5J6.0AHE3/61 equivalent, key selection criteria include clamping voltage under 10.3 V at 48.5 A, unidirectional polarity with cathode band marking, AEC-Q101 qualification status, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device during transients, leveraging an avalanche junction to divert surge energy away from protected ICs. Its glass-passivated chip junction ensures stable breakdown behavior and low leakage (<800 µA at 6.0 V), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
The SMA5J6.0AHE3/61 delivers 500 W peak pulse power per 10/1000 µs waveform with <1 ns response time and low incremental surge resistance. Thermal resistance is 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), enabling reliable operation up to +150 °C junction temperature in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche onset range; ensures predictable turn-on across production lot. |
| VC @ IPPM | ≤10.3 V at 48.5 A - Clamping voltage under full-rated surge; determines maximum stress on downstream MOSFET or IC. |
| PPPM | 500 W (10/1000 µs) - Peak transient energy handling capacity; defines protection level against IEC 61000-4-5 surges. |
| IFSM | 40 A (8.3 ms half-sine) - Forward surge rating; supports inrush current immunity in power supply input stages. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments. |
| Polarity | Unidirectional - Cathode marked by band; requires correct orientation in series with positive rail or signal line. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); cathode band denotes terminal 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry during forward conduction or surge shunting | Connected to ground or low-side return path; must handle full IPPM surge current without trace fusing. |
| Cathode (banded end) | Current exit during reverse-biased clamping | Connected to protected line (e.g., 5 V rail); polarity reversal causes catastrophic failure. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; required for ECU and ADAS modules. |
| Glass-passivated junction | Ensures stable VBR over lifetime and humidity exposure; eliminates parameter drift in harsh industrial environments. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without popcorn cracking or delamination; no pre-bake needed. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients (e.g., ISO 7637-2 pulse 5a); improves clamping precision. |
| 5.0 mm × 5.0 mm pad layout | Optimized thermal dissipation for 500 W pulses; reduces risk of PCB carbonization during repeated surges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0A-E3/61 | No AEC-Q101 qualification; commercial grade only; identical electrical specs and package. | Not suitable for automotive OEM designs requiring PPAP or AEC validation; acceptable for consumer or industrial prototypes. | Select SMA5J6.0AHE3/61 when automotive qualification is mandatory; choose E3/61 for cost-sensitive non-automotive volume builds. |
| SMA6J6.0AHE3/61 | 600 W PPPM rating (vs. 500 W); same VWM/VBR/VC; larger thermal mass but identical SMA footprint. | Higher surge margin for IEC 61000-4-5 Level 4 testing; may require updated thermal pad design for full 600 W dissipation. | Choose SMA6J6.0AHE3/61 if system-level surge testing exceeds 500 W requirements; retain SMA5J6.0AHE3/61 for validated 500 W designs. |
Compared with SMA5J6.0A-E3/61, the SMA5J6.0AHE3/61 adds AEC-Q101 qualification without altering electrical performance; versus SMA6J6.0AHE3/61, it trades 100 W peak power for tighter thermal constraints and proven fit in legacy 500 W layouts.

FAQ
What is the clamping voltage of the SMA5J6.0AHE3/61 under full-rated surge current?
The SMA5J6.0AHE3/61 clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 48.5 A (10/1000 µs waveform). This value is measured at the device terminals under standardized test conditions with 0.2" × 0.2" copper pads. The clamping voltage directly limits stress on downstream components like microcontrollers or interface ICs, making it a critical parameter for system-level surge immunity design. Always verify layout thermal performance to maintain this spec in production.
Is the SMA5J6.0AHE3/61 suitable for automotive applications?
Yes, the SMA5J6.0AHE3/61 is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation revision 09-Jan-2024. It meets stress test requirements for temperature cycling, high-temperature reverse bias, and mechanical shock-making it appropriate for engine control units, body electronics, and ADAS modules. Its MSL Level 1 rating also supports lead-free reflow in automotive manufacturing lines without pre-baking.
How does the SMA5J6.0AHE3/61 differ from the SMA5J6.0A-E3/61?
The SMA5J6.0AHE3/61 and SMA5J6.0A-E3/61 share identical electrical specifications (VWM = 6.0 V, VBR = 6.67–7.37 V, VC ≤ 10.3 V, PPPM = 500 W) and SMA (DO-214AC) packaging. The sole difference is qualification: HE3 denotes AEC-Q101 compliance for automotive use, while E3 is commercial-grade only. Both use RoHS-compliant matte tin plating and meet JESD 201 Class 2 whisker resistance. No PCB layout changes are needed when upgrading from E3 to HE3.
What is the maximum operating temperature for the SMA5J6.0AHE3/61?
The SMA5J6.0AHE3/61 has a maximum junction temperature (TJ max.) of +150 °C, as specified in Vishay's datasheet Document Number 88875. This rating allows operation in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. Derating curves in Figure 2 show that peak pulse power decreases linearly above 25 °C ambient, requiring thermal design consideration-especially when mounted on minimal copper area.
Does the SMA5J6.0AHE3/61 have polarity markings, and how is it oriented in circuit?
Yes, the SMA5J6.0AHE3/61 is unidirectional and features a visible cathode band on the SMA (DO-214AC) package body. During circuit placement, the banded end connects to the protected line (e.g., 5 V rail), and the unmarked end connects to ground. Reversing polarity prevents clamping action and risks catastrophic failure under surge. The band aligns with standard diode marking conventions and is verified in Vishay's mechanical drawings and application notes.
